Borg BL2127 Marine Grade Easicode Pro Deadbolt - Back-to-Back Keypads - Matt Black

At A Glance
PIN codePIN Code
(Both Sides)

The Borg BL2127 is the back-to-back (BTB) version of the Borg BL2107 - a fully mechanical pushbutton deadbolt with Easicode Pro (ECP) on-door code change. Both the outside and inside of the door carry a full keypad, and the correct code is required to retract the deadbolt from either side. There is no free inside egress on this configuration - the inside keypad must be operated to unlock the door from within, so check this suits your application before ordering.

Built from a cast housing with stainless steel buttons and finished in Matt Black marine external grade coating (MG Pro), the BL2127 is tested to 1,000 hours salt spray for coastal, marine and saline environments. Easicode Pro allows the code to be changed while the lock stays installed on the door, and an optional code change disabling plug is included for each keypad, letting you lock out unauthorised code changes from either side independently.

The BL2127 uses a 25mm throw mortice deadbolt with a dual 60mm/70mm backset follower included as standard, so one lock covers two common backset spacings. The inside knob gives codeless locking - the door can be secured from inside with a simple turn, no code required - while unlocking from inside still needs the correct code entered on the inside keypad. Suits doors 35-85mm thick and is rated for external medium duty doors and gates.

Estimated Warehouse Dispatch
Usually same day if ordered before 11am AEST (excluding weekends and Queensland public holidays).
Easicode Pro - On-Door Code Change
The code can be changed while the lock stays installed on the door - no removal needed. Both keypads share one active code, and the change procedure can be performed from either side. See how to change the code below, or read our guide to changing codes on mechanical digital locks.
Back-to-Back Keypads - No Free Inside Egress
Both the outside and inside of the door have a full keypad, and the correct code must be entered to retract the deadbolt from either side. To lock the door from inside without a code, turn the inside knob - this throws the deadbolt directly (codeless locking). To unlock from inside, the correct code must be entered on the inside keypad. Confirm this suits your application and complies with any applicable fire egress or building regulations before purchasing - if you need free exit from inside without a code, the single-sided Borg BL2107 is the better fit. See our guide to how back-to-back keypad locks work.
Marine Grade (MG Pro)
Suitable for coastal and saline environments - tested to 1,000 hours salt spray. Regular monthly silicon-based lubrication (see Maintenance Guide) helps maintain corrosion resistance in exposed locations. Read more about what MG Pro means and how it compares on salt spray testing.

Easicode Pro - How to Change the Code

The code can be changed with the lock installed on the door. The door must be open. You need to know the current code before changing it. The procedure is the same on either keypad - both keypads then operate on the new code.

  1. Enter the existing code on either keypad.
  2. Insert the code change key into the hole in the * button. Press fully and hold until step 5.
  3. Press the C button to clear the existing code.
  4. Enter the new code.
  5. Release the code change key from the * button.
  6. Press C to set the new code.
  7. The new code is now active on both keypads.
  8. Test the new code 5 times on both sides, confirming it withdraws the bolt, before closing the door.

If a mistake is made during code entry while the * button is held, press C to cancel and start again from step 3 - the C button resets during programming without releasing the * button.

Maintenance Guide

Monthly: Apply a light spray of silicon-based lubricant (such as GT85) to both keypad surfaces and all exposed elements of the deadbolt assembly. Remove excess with a soft cloth. Do not use oil-based lubricants such as WD-40 - these attract dirt and can damage internal components.
Annually:
  1. Remove the lock from the door.
  2. Spray the inside of both keypads with GT85 or similar silicon-based lubricant through the tumbler holes on the reverse. Remove excess with a soft cloth.
  3. Spray all fixings, accessories and the deadbolt with silicon-based lubricant.
  4. Push each button on both keypads and operate the deadbolt several times to confirm smooth operation and that all buttons return fully to their outward position.

Frequently Asked Questions

What is the difference between the BL2127 and the BL2107?
The BL2127 is the back-to-back version - it has a full keypad on both sides, requiring a code to unlock from either side. The BL2107 is single-sided - keypad outside only, with a free inside handle that operates the bolt without a code. Choose the BL2127 where controlled access from both sides is required; choose the BL2107 where free inside egress is needed.
Can I open the door from inside without the code?
No. The inside keypad requires the correct PIN to retract the deadbolt. To lock the door from inside, turn the inside knob (codeless locking). To unlock from inside, enter the code on the inside keypad. Confirm this suits your application and complies with any applicable fire egress regulations before installing.
Do both keypads share the same code?
Yes. Both the outside and inside keypads operate on a single active code. The change procedure can be performed from either keypad - once changed, the new code is active on both sides immediately.
Does this lock have a key override?
No. The BL2127 is code-only on both sides - there is no mechanical key backup on this model. If you need a key override as a backup, the Borg BL7701 is a heavier duty option that includes one.
Is the BL2127 suitable for pool gates?
The BL2127 is rated for external medium duty doors and gates and is salt spray tested to 1,000 hours, but requiring a code from inside to exit may conflict with pool safety egress requirements in most Australian jurisdictions - self-latching, self-closing and free-egress rules typically apply. Confirm your local pool gate compliance requirements with a licensed pool safety inspector before specifying this back-to-back model for a pool barrier.

Additional Information

Spindle Orientation: Position the spindle facing towards the top opening edge of the door, viewed from the keypad side. Use the longest spindle supplied - a spindle that is too short can shift out of position if the door is slammed. If the spindle needs to be cut, only cut from the inside handle side; the keypad side must not be cut, as the full bladed portion is required there.
Dual Backset Follower: The deadbolt includes both a 60mm and 70mm follower as standard - select the correct follower to match your door's mortice position on installation. No additional parts are required for either backset. See our guide to measuring your lock backset if you're unsure which you need.
Handing: The BL2127 is fully reversible and suits left and right hand doors with no parts to swap - handing is set on installation, not at time of order.
Choosing Between the BL2107 and BL2127: Both share the same deadbolt body, backset, door-thickness range and marine grade coating - the only functional difference is whether the inside is a free-turning handle (BL2107) or a second keypad (BL2127). If you're not sure which suits your gate or door, our guide to back-to-back locks for gates covers when each configuration makes sense.
Borg Locks Warranty - 12 Months (Australia)
All Borg locks are warranted against mechanical defects in materials and workmanship under normal use and service for a minimum of 12 months from date of sale.

Borg BL2127 - FAQ, Setup and Owner's Guide

Everything below is here to help you buy, install, code and live with your Borg BL2127 back-to-back deadbolt. For the wider mechanical digital category see our Mechanical Digital Locks Buyer's Guide chapter, and for the full Digital Mechanical Locks range see the category page.

Access and Back-to-Back Operation

What does "back-to-back" mean on the BL2127?
It means the lock has a complete, working keypad on both faces of the door - not just a keypad outside with a plain handle inside. Both keypads share one active code, and that code must be entered on whichever side you're operating the lock from, including from inside. Our explainer on double-sided locks covers the concept in more depth, including when it's the right choice for gates.
Why would I choose a lock with no free inside egress?
Back-to-back locks exist for situations where you genuinely want the same level of control on both sides of the door or gate - a side gate to a pool-adjacent yard where you don't want children able to open it freely from either direction, a shared boat shed where both directions need auditing by code, or a commercial gate where staff enter and exit through the same controlled point. If you just want a normal front door where anyone inside can always get out, the single-sided BL2107 is almost always the better fit.
What is codeless locking and how does it differ from holdback?
Codeless locking means you can secure the door from inside with a simple turn of the knob - no code entry needed to lock it, only to unlock it. This is not the same as a holdback (or passage) mode, which some Borg models offer, where the lock is held open and won't lock at all until manually released. The BL2127 always locks when the inside knob is turned; it has no holdback function. See our guide to passage mode vs holdback mode if you're comparing options across the Borg range.

Code Change and Lockout

Do I need to change the code from both keypads?
No - the code change procedure can be started from either keypad and it updates the shared code on both sides at once. You don't need to repeat the process on the second keypad. See the full step-by-step code change guide above, or our general guide to changing codes on Borg ECP models.
What do the code change disabling plugs actually do?
Each keypad has its own disabling plug. Fitted into the * button hole, it physically blocks the code change function from that side only. You might disable the outside plug so tradespeople or staff can use the lock day to day but can't change the code, while keeping the inside plug free for the property owner - or disable both if code changes should only ever be done by a locksmith. Both plugs can be fitted or removed independently at any time.
I've forgotten the code and can't get in - what now?
Because this model has no key override, a forgotten code with both disabling plugs fitted (or a genuinely lost code) will lock you out - there is no mechanical backup entry on this SKU. Keep the code recorded somewhere secure, and consider whether a model with key override (such as the Borg BL7701) is a better fit if a physical backup matters for your application. Contact Terry's Locksmiths for lockout assistance.

Marine Grade, Salt Spray and Weather

What does "MG Pro" and 1,000 hours salt spray actually mean?
MG Pro is Borg's marine grade coating tier, and 1,000 hours is the duration the finish was tested to withstand a continuous salt spray without failing per the relevant test standard - a benchmark for corrosion resistance in coastal air, not a literal hours-of-use figure. Our MG Pro explainer and its salt spray testing section break down how this compares to other Borg coating tiers and to AS 4145.2 classes.
How often should I lubricate a coastal installation?
Monthly, minimum, in exposed coastal or marine locations - see the full Maintenance Guide above for the exact steps and the annual deeper-clean procedure. A silicon-based lubricant such as GT85 is recommended; oil-based products like WD-40 attract salt-laden dirt and grit rather than repelling it.

Installation and Fitting

How do I know whether I need the 60mm or 70mm backset?
You don't need to choose at time of order - both followers are included in the box, and you select the correct one to match your door's existing mortice position during installation. Not sure how to measure? See our guide to measuring your lock backset.
My door or gate is right at the edge of the 35-85mm range - what should I check?
The lock body and standard fixings suit 35-85mm door thicknesses with the supplied 120mm spindle. If you're specifying for a heavier gate frame outside this range, contact Terry's Locksmiths to confirm fit before ordering rather than guessing - our advice and installation service can help.
Does the spindle need to be cut for a thinner door?
Possibly. Use the longest spindle supplied and only trim from the inside handle side if it's too long for your door - never cut the keypad side, since the full bladed portion is needed there for the keypad mechanism to engage correctly. Full guidance is in the Easicode Pro Instructions PDF.

Suitability

Is this a good fit for a pool boundary gate?
Not typically, on its own. Australian pool barrier rules generally require self-closing, self-latching hardware with free egress, which a code-required-both-sides deadbolt does not provide from the inside. It can work as a secondary, non-pool-boundary gate (a side yard gate, a rear boat shed) where free egress isn't a compliance requirement - always confirm with a licensed pool safety inspector for anything forming part of the pool barrier itself.
Is this suitable for a busy commercial entrance?
No - it's built for light to medium use, not high-traffic commercial doors. For that application see the Lockwood 3572DX, Borg BL7701 or Carbine CDL7100SC-HD heavy duty ranges.
