Yale Unity Slim Smart Lock with Multipoint Locking System

The Yale Unity Slim Smart Lock is a keyless smart lock built for hinged doors with narrow stiles. Its sleek, narrow escutcheon and multi-backset mortice suit both aluminium and timber framed doors, which makes it one of the few genuine smart lock options for the aluminium front doors now common on new Australian homes.

Access is by 6-digit PIN on the built-in keypad or through the Yale Home App over Bluetooth iOS App StoreAndroid Google Play. A built-in Yale module means the lock works with the Yale Home App and Apple HomeKit straight out of the box, with no separate network module to buy. Add the Yale Connect Plus Hub 2 (sold separately) when you want remote access from anywhere plus Amazon Alexa and Google Home voice control.

Security comes from the Induro lift-to-lock mechanism. Lift the handle and the lock throws all of its points at once: latch, deadbolt and, in the 4-Point configuration, the top and bottom shoot bolts. That single action both secures the door and compresses the weather seal, which matters on large aluminium panels. A door position sensor is supplied so the lock knows whether the door is genuinely closed before it locks. It is built in a range of configurations - 30mm, 40mm, 50mm and 60mm backsets, in 4-Point or 2-Point, with short throw or long throw options - so it can be matched to an existing door preparation. This is a 100% key free lock - there is no mechanical key override, so plan a backup before you buy.

Key Features

  • Multipoint locking, lift to lock - one lift of the handle throws every locking point and compresses the door seal.
  • Induro 4-Point configuration for aluminium frames (latch, deadbolt and two shoot bolts) or a 2-Point configuration for timber and for retrofits onto existing Optimum and Induro 2-point systems.
  • Four backsets - 30mm, 40mm, 50mm and 60mm - in 4-Point or 2-Point, with short throw and long throw options.
  • Narrow escutcheon just 37.5mm wide - fits slender aluminium stiles where a standard smart lock cannot.
  • 6-digit keypad entry storing up to 100 user codes, plus a single-use one-time code.
  • Built-in Yale module - Yale Home App over Bluetooth and Apple HomeKit work straight out of the box, with no network module to add.
  • Auto-lock (10 seconds by default) and auto-unlock as you approach, both managed from the app.
  • DoorSense door position sensor supplied - the app tells you whether the door is closed and locked, not just locked.
  • Fake PIN code lets you pad your real code with random digits so it cannot be read over your shoulder.
  • 3-minute lockout after five failed attempts, plus a Security Lockout Mode that disables the outside keypad entirely.
  • Genuine tamper alarm and internal intrusion alarm, with voice prompts guiding set-up.
  • Emergency USB-C power on the underside of the external body if the batteries ever run flat.
  • DualDoor ready - pair with the Yale Unity Security Screen Door Lock through a Connect Plus Hub 2 to work both doors in one action.
  • Weather built: IP55 external module, UV-tested screen, powder-coated diecast body and a stainless-steel faceplate.
  • Tested to AS4145.2.2008 - SL7 security, D7 durability; RCM compliant for Australia and New Zealand, with ASSA ABLOY Cyber Security Declaration Cyber-AU-00030.

  • Households pairing a front door and a security screen door with DualDoor through a Connect Plus Hub 2
Not suitable for
Gates, or any opening where the escutcheon is exposed to the weather - Yale rates this product for residential entry doors only. It is also the wrong choice if you need a mechanical key backup, since there is no key override. On the coastal Gold Coast, read how salt air affects electronic locks and the Yale coastal installation notes.

Available Finish Options

  • Matt Black

    (This Product)
    YURSSL

Matt black powder coat over a diecast body, with a UV-tested screen and a stainless-steel faceplate. Finish selection does not affect functionality, compliance, or performance.

Available Configurations

Three things decide which Unity Slim you need: the backset (door edge to spindle centre), the number of locking points, and the bolt throw. Measure the existing lock before ordering - none of the three can be changed on site. The published part numbers are below.

Locking Points Backset Bolt Throw Part Number
Induro 4-Point 30mm Short throw YURSSL0430400B
Induro 4-Point 30mm Long throw YURSSL0431400B
Induro 4-Point 40mm Short throw YURSSL0440400B
Induro 4-Point 50mm Short throw YURSSL0450400B
Induro 4-Point 50mm Long throw YURSSL0451400B
2-Point 30mm Short throw YURSSL0230400B
2-Point 30mm Long throw YURSSL0231400B
2-Point 40mm Short throw YURSSL0240400B
2-Point 50mm Short throw YURSSL0250400B
2-Point 50mm Long throw YURSSL0251400B
2-Point 60mm Short throw YURSSL0260400B

Every configuration is supplied with a matching stainless steel strike. 4-Point adds a top and a bottom shoot bolt and is the usual choice on aluminium frames and tall or wide panels; 2-Point omits the shoot bolts and is the retrofit option for existing Optimum and Induro 2-point systems. Not sure which throw you need? Read what is bolt throw and why it matters, then confirm your backset. Not every backset and throw combination is published as a stocked trade pack - if the one you need is not listed, or you are unsure, send us a photo of the existing lock and we will match it.

How Multipoint Locking Works

Lifting the handle drives every locking point at once. In the Induro 4-Point configuration that is the latch, the deadbolt and the top and bottom shoot bolts into the frame head and sill. Pulling the handle down retracts them all. The single action is what gives the door both its security and its seal compression, and it is why the Unity Slim suits large aluminium panels that tend to bow.

Yale Unity Slim operational schematic showing the top shoot bolt, latch, deadbolt and bottom shoot bolt engaged by lifting the handle
Induro 4-Point locking: top shoot bolt, latch, deadbolt and bottom shoot bolt, all thrown by one lift of the handle.
Auto-lock does not throw the multipoint bolts
Auto-lock, the inside status indicator button and the app all lock the door, but multipoint locking is only engaged by lifting and releasing a handle. If you leave through the door, lift the outside handle before auto-lock runs; if you have come inside, lift the inside handle. This is a mechanical characteristic of every lift-to-lock system, not a fault.

Battery, Power & Emergency Access

  • Runs on 4 x AA alkaline batteries (included), split two in the top compartment and two in the bottom. Yale rates a set at around 12 months at ten uses a day.
  • The low battery warning begins at 20%: the external LED flashes red, the lock says to replace the batteries, and the app raises a notification. Replace all four batteries together.
  • Use alkaline batteries only. Lithium and rechargeable cells can cause the lock to malfunction.
  • If the batteries do go flat, a USB-C cable and a power bank on the port under the external body will power the keypad long enough to enter a code and get in. There is no mechanical key on this model, so keep a cable and power bank somewhere sensible.
  • Battery life on any electronic lock is mostly a function of how well the door is aligned - a binding door works the motor harder. See what really affects battery life and the Yale low-battery notes.

Remote Access & Smart Home

  • Out of the box the built-in Yale module gives you the Yale Home App over Bluetooth and Apple HomeKit at the lock. There is no separate network module to buy and no Wi-Fi radio inside the lock.
  • Adding the Yale Connect Plus Hub 2 (sold separately) is what turns on remote lock and unlock from anywhere, live activity notifications, remote PIN changes and Amazon Alexa Amazon Alexa and Google Home Google Home voice control.
  • One Hub 2 covers up to 16 Bluetooth Yale devices, so a front door lock, a screen door lock and a keypad can all run from the same gateway. Compare gateways in Chapter 08.
  • DualDoor: pair the Unity Slim with a Yale Unity Security Screen Door Lock through the Hub 2 and one action works both doors. Read Dual Unlock explained and check your screen door clearance first.
  • The Yale Home App is available for iOS and Android iOS App StoreAndroid Google Play. Not sure which ecosystem suits you? Read which app platform is right for you.

Cyber Security Declaration
ASSA ABLOY Australia has issued an Australian Cyber Security Declaration for the Yale Unity Slim Smart Lock: Declaration Cyber-AU-00030, hardware Rev 1, firmware V1.6.0, with a 3-year product support period, covering the Yale Home app on iOS and Android. Confirmed 29 January 2026. Download the Cyber Security Declaration (PDF).

Security Features

Fake PIN code
Type any number of extra digits before or after your real 6-digit code and the lock still finds the genuine code inside the string. It is the simplest defence against someone watching you at the door.
3-minute lockout
Five failed code attempts locks the keypad for three minutes, which makes guessing impractical. Enter a valid user code, or press the button for five seconds, to clear it early.
Security Lockout Mode
Hold the inside status indicator button for four seconds and the external keypad and app control are both disabled until you release it the same way. Useful overnight or while the house is occupied. The LEDs flash blue while it is active.
Internal intrusion alarm
Armed from the keypad with the master code, this sounds if the door is opened from the inside. It is aimed at households wanting to know if a door is being used while they are home.
Tamper alarm
The lock sounds if the external body is separated from the internal body or if the door is forced. As a genuine Yale (ASSA ABLOY) feature these alerts are real, not the phantom triggers seen on some other platforms.
LED status at a glance
Green flash means unlocked, red means locked, blue means Security Lockout Mode is on, and a red flash on the outside only is the low-battery warning.

Frequently Asked Questions

Do I need a hub, and does the lock have its own Wi-Fi?
The lock has no Wi-Fi of its own. Its built-in Yale module is Bluetooth, which is enough for the Yale Home App when you are near the door and for Apple HomeKit at the lock. Buy the Connect Plus Hub 2 only if you want control from anywhere plus Alexa and Google voice control. More in Chapter 08 - do you need a gateway.
What is the difference between the 4-Point and 2-Point configurations?
4-Point adds a top and a bottom shoot bolt to the latch and deadbolt, and is the usual choice on aluminium frames and tall or wide panels because of the extra seal compression. 2-Point drops the shoot bolts and is the retrofit option for existing Optimum and Induro 2-point systems, where no door routing is required, though the strike plate must be swapped because the projection changes to a lift bolt. Both are made across the backset range with short and long throw options - see Available Configurations for the published part numbers.
There is no key - how do I get in if the batteries die?
Plug a power bank into the USB-C port on the underside of the external body and the keypad wakes up long enough for your code. The lock warns you at 20% battery through the LED, a voice prompt and an app notification, so a flat lock should never be a surprise. If a guaranteed mechanical backup matters to you, look at a keyed model such as the Yale ByYou Pro instead.
Can I fit it myself?
Only if you are set up for it. The Induro mortice has to be installed first and the stile routed to the supplied template, then the external and internal bodies, the door position sensor cable and the strike all have to line up. Most owners are better served by a locksmith - misalignment is the single biggest cause of smart lock complaints. See when to DIY and when not to, or book a site survey.
Which configuration do I order?
Three choices decide it: backset (30mm, 40mm, 50mm or 60mm), locking points (4-Point or 2-Point) and bolt throw (short or long). The published part numbers are listed in Available Configurations. Measure from the door edge to the centre of the spindle hole before ordering - none of the three can be adjusted out on site. Help with measuring your backset, bolt throw and Chapter 02.

Additional Information

The master code is keypad-only, and it matters
The master code is set at the lock and can only be changed at the lock, never in the app. Lose it and the only route back is a full factory reset, which wipes every user code. Write it down and store it away from the door. Connecting the lock to the Yale Home App resets every other setting to default but leaves the master code alone.
Once the app is connected, the keypad stops being the control panel
After pairing, user codes, one-time codes, auto-lock, auto-unlock and volume can only be customised in the Yale Home App. That is a deliberate design choice, not a fault, and it catches out owners who set the lock up at the door first. If you never intend to use the app, the lock can be programmed entirely from the keypad instead.
Door alignment is the whole job
A multipoint lock is only as good as the frame it closes into. The shoot bolts, the deadbolt and the latch all have to find their keeps at the same time, and the door position sensor magnet has to sit directly opposite the sensor. Allow for adjustment on a door that has settled, and use the strike packer rather than forcing the door. Common errors are set out in three common installation mistakes.
Coastal exposure and the Yale warranty
The Unity Slim is UV tested and IP55 on the outside module, which suits it to an exposed Gold Coast front door far better than most. Yale's warranty still excludes corrosion from coastal air and salt spray, so a wash-down of the external escutcheon every few months is a sensible habit within a couple of streets of the water. Background: Yale coastal installations.
Where the Unity Slim sits in the Yale range
The Unity Slim is the narrow-stile multipoint lock. For a standard timber hinged door on a single-point latch, the Unity Entrance is the direct sibling; for a security screen door it is the Unity Security Screen Door Lock. If you want fingerprint or a mechanical key, move to the mortice range: ByYou Pro, Kyra Pro or the face-recognition Luna Pro+. The full picture is in the Yale brand profile.

Yale Unity Slim - FAQ, Setup and Owner's Guide

A deep reference for the Yale Unity Slim Smart Lock (SKU YURSSL) covering access, multipoint locking behaviour, remote access, power, fit, programming and troubleshooting. It is written from the Yale Unity Slim User Guide, Installation Instructions, Routing Template, Technical Specifications and the 2025 Yale Smart Locks Catalogue, reworded for Australian buyers. For general questions see Chapter 13 - Smart Lock FAQ, and for the full range read the Ultimate Smart Lock Buyer's Guide.

Access and Credentials

How many codes can the Unity Slim hold?
Up to 100 user codes, plus the master code and a one-time code. User slots are numbered 01 to 100, with slot 100 entered as 00 when you are programming at the keypad.
How long can a PIN code be?
Exactly six digits. Unlike some brands there is no 4 to 8 digit range on this model - user codes, the master code and the one-time code are all six digits. Compare credential types in Chapter 03 - Access Methods.
What is a one-time code and when should I use it?
A single-use six-digit code that the lock deletes automatically the moment it is used. It suits a one-off tradesperson or delivery. Only one one-time code exists at a time.
How do I wake the keypad?
Touch the keypad with your palm. The numbers light up and you can enter your code. This is a wake gesture, not a palm credential.
Can I use a contactless key tag or a card?
No. RFID key tags work on the Unity Entrance and Unity Screen Door locks, not on the Unity Slim. If key tags matter to your household, look at the Unity Entrance range instead.
Is there a fingerprint option?
Not on the Unity Slim. Yale's fingerprint models are the mortice range - the ByYou Pro with its Grab-and-Go sensor in the handle, and the Kyra Pro. The Yale Smart Keypad 2 adds fingerprint to Unity locks that have no keypad of their own; the Unity Slim already has one built in.
How does the Fake PIN feature actually work?
Enter random digits before your real code, after it, or both, then press the confirm button or palm touch. The lock searches the string for a valid code and opens. Anyone watching sees a long meaningless sequence.

Locking Behaviour and Multipoint

How do I lock the door properly when I leave?
Push the handle down to unlock and open the door, step outside, then lift and release the outside handle. That lift is what engages multipoint locking. If auto-lock is enabled, lift the handle before the timer runs.
And when I come home?
Unlock with the keypad, the app or auto-unlock, pull the handle down and open the door. Once inside, lift and release the inside handle to re-engage multipoint locking.
Does auto-lock throw the shoot bolts?
No. Auto-lock, the inside status indicator button and the Yale Home App all secure the door, but only lifting and releasing a handle drives the full multipoint set. After locking by any of those other methods, lift the inside handle to complete the multipoint engagement.
How long is the auto-lock delay?
Ten seconds by default. When auto-lock is on and the lock is not muted, it beeps as the door closes to warn you it is about to lock. Timing is adjusted in the Yale Home App once the lock is paired.
How does auto-unlock know I am home?
It combines your phone's Bluetooth, Wi-Fi and GPS to detect that you left the area and have returned, then unlocks as you reach the door. It can only be switched on and tuned in the app, and it needs location permissions left enabled on the phone.
What does the door position sensor add?
It tells the app whether the door is actually closed, not just whether the lock has thrown. That prevents the lock trying to secure an open door and lets you check from your phone whether the door was left ajar. The magnet sits in the strike, or in the separate heavy duty magnet housing on a retrofit.

Remote Access, Voice and DualDoor

What exactly does the Connect Plus Hub 2 unlock?
Remote lock and unlock from anywhere, remote PIN changes, live activity notifications and voice control through Amazon Alexa and Google Home. Without it the lock is a capable Bluetooth and HomeKit lock, and everything still works at the door. Full spec on the Connect Plus Hub 2 page.
Where should the hub go?
Within Bluetooth reach of the lock and on 2.4GHz Wi-Fi. Brick, stone and concrete internal walls between hub and lock will cut the range, and a large home may need the hub relocated rather than a second one. Placement advice in Chapter 08 - placement.
What happens if the internet drops out?
You lose remote access and voice control only. The keypad, the app over Bluetooth and Apple HomeKit at the lock all keep working, and the hub reconnects by itself when the internet returns. See what happens when the internet is down and why smart locks drop off Wi-Fi.
Does Apple HomeKit need the hub?
No. The built-in Yale module gives HomeKit at the lock straight out of the box, so Siri and the Apple Home app work over Bluetooth. A HomePod or Apple TV acting as a home hub is what extends HomeKit control beyond Bluetooth range.
How does DualDoor work with a screen door?
Pair the Unity Slim and a Yale Unity Security Screen Door Lock to the same Yale Home account with a Connect Plus Hub 2, then link them in the app. One action then works both doors. DualDoor relies on an internet connection, so keep app access and a way into both doors independently. Read Dual Unlock explained.
Can I give someone temporary access from my phone?
Yes. The Yale Home App issues guest access on an always, recurring or temporary schedule, and keeps a 24/7 activity trail of who came and went. Guests need an internet connection on their own phone so the server can check their access window.

Power and Batteries

Which batteries, and how many?
Four AA alkaline cells, two in the top compartment and two in the bottom. Yale is explicit that lithium and rechargeable cells must not be used because they can make the lock malfunction. Replace all four at once, never in pairs.
How will I know the batteries are low?
The external LED flashes red, the lock speaks a replace-the-batteries prompt when you lock or unlock, and the Yale Home App raises a low battery notification. Yale prints the warning threshold at 20%.
What do I do if the lock is completely flat?
Connect a power bank to the USB-C port on the underside of the external body. That powers the keypad temporarily so you can enter a user code and get inside, then change the batteries. There is no mechanical key on this model.
Twelve months sounds optimistic. Is it realistic?
Yale's figure assumes a well-aligned door and around ten operations a day. A door that drags, a stiff multipoint mechanism or heavy traffic will shorten it. Cold and very humid conditions also cost some capacity. Our honest take is in the realities of electronic door locks and the Yale battery life issue.

Fit, Installation and Door Preparation

Will it fit my door?
It suits aluminium or timber hinged doors 35mm to 60mm thick, in 30mm, 40mm, 50mm and 60mm backsets, in 4-Point or 2-Point with short or long throw options, and works on left or right-hand opening doors. The escutcheon is only 37.5mm wide, which is what lets it go on slender stiles. Measure before ordering using Chapter 02 - stile width.
Short throw or long throw - how do I choose?
Bolt throw is how far the bolt projects into the frame. A longer throw resists a kicked door better and suits frames where the gap between door and jamb is wider; a short throw suits a standard, well-fitted aluminium frame. If you are replacing an existing multipoint lock, match what is already there, because the strike and keeps are cut for that projection. Background in what is bolt throw.
Does the door have to be routed?
For a new 4-Point installation, yes - the stile is routed to the supplied 1:1 template, 198mm long for a standard forend plate or 278mm for the extended plate, with the routing set back 28mm, 38mm or 48mm from the face depending on the backset. Replacing an existing Optimum or Induro 2-point system with the 2-Point Unity Slim needs no routing, but the strike plate must be changed because the projection becomes a lift bolt.
How is the handing set?
Both handles are rotated to suit the door's opening direction during installation. On the external body the handing tab sits under the gasket, which has to be peeled back and then refitted properly so the gasket spigots seat in their holes and the weather seal is maintained. Handing explained in door handing in Australia.
Which spindle and screws do I use?
That depends on door thickness: short spindle with short screws for 35-44mm, short spindle with medium screws for 44-48mm, long spindle with medium screws for 48-53mm, and long spindle with long screws for 53-60mm. A compression spring goes into the internal body handle hole in every case. Spares are in the Unity Slim screw pack.
Is there anything easy to get wrong?
Three things. Do not fit the batteries and operate either body before both are mounted on the door - that can make the lock malfunction. Do not pinch the external body cable or the door position sensor cable when you draw the bodies together. And the plugs on the internal circuit board only fit one way, so never force them. Test by lifting and lowering the inside handle before the covers go back on.
What if the old lock has left marks on the door?

Setup and Programming

What is the recommended setup order?
Register the master code at the keypad first, then download the Yale Home App, create or sign in to an account, choose to set up a new device, scan the QR code behind the top battery cover or on the box, put the lock into app pairing mode and finish in the app. Pairing mode stays open for five minutes.
Why did my keypad settings disappear after I connected the app?
Connecting to the Yale Home App restores every lock setting except the master code to default. It is expected behaviour. From that point user codes, one-time codes, auto-lock, volume and auto-unlock are managed in the app only, so set the lock up in the app first and add your codes there.
Can I run the lock without the app at all?
Yes. Everything essential can be programmed at the keypad: register or change the master code, add and delete user codes, set the one-time code, delete all user codes, enable or disable auto-lock and set the volume to high, low or silent. You give up auto-unlock, remote access, the activity trail and guest scheduling.
Where is the registration button?
Under a battery cover on the internal body, marked with an R. It starts and completes programming sessions at the keypad. The status indicator button sits beside it and is used for locking from inside and for Security Lockout Mode.
What happens if I forget the master code?
It cannot be recovered or reset from the app, only from the lock. You will need a full restore of default settings, which erases every user code including the master code, and then create a new master code before anything else can be programmed. Store it somewhere safe. Step-by-step help is in our Unity Slim reset guide.

Troubleshooting and Reset

What is the difference between a factory reset in the app and restoring default settings at the lock?
A factory reset in the Yale Home App disconnects your account from the lock. Restoring default settings at the lock deletes all user codes and the master code and returns every feature to default, but does not disconnect the app account. If you are handing the lock on to a new owner, do both. Our Unity Slim troubleshooting and reset guide walks through each one.
How do I restore default settings at the lock?
Take off the battery covers and batteries, remove the internal body to reach the reset button, hold that button while you reinstall the batteries, and release it when you hear the completed prompt about ten seconds later. Refit the covers, then create a new master code - it is the only option available until you do.
An alarm is sounding. How do I stop it?
For the internal intrusion alarm and the tamper alarm, open the door from the inside with the internal handle and press the button. For a 3-minute lockout, enter a registered user code or press the button for five seconds. To leave Security Lockout Mode, hold the internal status indicator button for four seconds until you hear the prompt.
The handle feels stiff or the bolts will not throw cleanly.
That is nearly always alignment rather than the lock. Check that the door closes flush, that the shoot bolt keeps line up in the head and sill, and that the strike is packed correctly. A door that has dropped on its hinges will fight a multipoint mechanism every time. Start with misalignment.
The keypad is not responding.
Palm touch it first to wake it, then check the LED. A red flash on the outside only means the batteries are low. No response at all usually means flat batteries, so try the USB-C emergency power. If it lights but rejects a known code, the lock may be in Security Lockout Mode or a 3-minute lockout. More at keypad unresponsive.

Suitability, Care and Compliance

Can I use it on a gate?
No. Yale rates the Unity Slim for residential entry doors and specifically excludes openings where the escutcheon is exposed to outdoor elements, such as a gate. The IP55 rating covers the outside module in normal door service, not full weather exposure of the whole assembly.
Is it fire rated?
No. The Unity Slim carries AS4145.2.2008 SL7 security and D7 durability but no fire rating. For a fire door you need the Unity Entrance Fire Rated, or the DDA lever version where accessibility also applies. Background in Chapter 05 - Fire Door Smart Locks.
Is it suitable for an NDIS or accessible project?
The Unity Slim is not a DDA-certified leverset. Where AS1428.1 compliance is specified, the Unity Entrance with DDA lever is the Yale answer. See Chapter 09 - DDA, NDIS and Accessibility.
How should I clean it?
A damp cloth only. Never use solvents, petrol or benzene - they damage the electronics and strip the finish. On a coastal door, rinse salt off the external escutcheon regularly; Yale excludes corrosion from its warranty, and salt air is the single biggest killer of electronic locks on the Gold Coast.
Is it a good choice for a rental or holiday let?
It works well where you want codes instead of keys and no key handover at all - though remember there is no mechanical backup and the guest experience depends on the app for scheduling. Add a Connect Plus Hub 2 if you need to change codes remotely between stays. See Yale for rentals and Chapter 07 - Airbnb and Short-Stay.

Installation & Assembly

Yale Unity Slim exploded assembly showing the internal body, mounting screws, spindle, Induro mortice lock, strike and external body
Exploded assembly: internal body, mounting screws, spindle, Induro mortice lock, strike and external body. The supplied strike may differ from the one shown.

Installation sequence in brief: fit the Induro mortice first, set the handing on both handles, remove the battery covers, feed the door position sensor wire through the mortice hole, choose the spindle and screws for your door thickness, fit the compression spring, mount the external body and then the internal body, plug in the external body and sensor cables, fix the bodies together, test the handle lift, fit the strike so its magnet sits opposite the sensor, then install the batteries.

Do not power the lock before it is on the door
Yale is explicit that the batteries must not be installed and the external or internal body operated before both are mounted on the door. Doing so can make the lock malfunction. Take equal care not to pinch either cable as the bodies are drawn together, and never force the circuit board plugs - they only fit one way.

Full step-by-step detail is in the Installation Instructions and the 1:1 Routing Template. If you would rather not cut the door yourself, book a Terry's installation.
