Mechanical Key(Lockout Only - Not Entry)
The Borg BL5050SC is a fully mechanical digital lock in a lever/lever back-to-back (BTB) configuration built around a 60mm backset euro profile mortice lockcase instead of a tubular latch. Both faces of the door carry a full lever keypad with an independent coding chamber - a code is required to pass through in either direction, with a different code available on each side if wanted.
What sets the BL5050SC apart from the tubular-latch BL5051 is the key lockout function. The mortice lockcase accepts a separately sourced euro profile cylinder: turn the key and the door is deadlocked - while deadlocked, neither keypad will operate the lock. A keyholder can shut down all code access after hours without changing or removing a single code, then restore it with one turn of the key in the morning. Two euro escutcheons are supplied to dress the cylinder position on both faces. The euro cylinder itself is not included - source it through Terry's, keyed alike or master-keyed to the rest of the site if wanted.
The lock is fire rated to AS 1905.1-2005 (up to 4 hours, doorset dependent), reversible on site, satin chrome finished for internal doors, and - being entirely mechanical - needs no batteries, wiring or power at any point. Browse the full battery-free range in our Digital Mechanical Locks category.

Euro Profile Mortice Lockcase - Not a Tubular Latch
The BL5050SC drives a 60mm backset euro profile mortice lockcase (85mm spindle-to-cylinder centres, 168mm case, 240mm x 24mm faceplate) morticed into the door edge - a more substantial locking body than a tubular latch, with saw protection built into the bolt. The euro profile cutout accepts a separately sourced cylinder for the key lockout function. Full case drawing in the Dimensions section. If you would rather the simpler tubular-latch install, the BL5051 is this lock's tubular sibling.

Key Lockout (Code Lockout) - Euro Cylinder Required, Not Supplied
Fit a euro profile cylinder into the lockcase and the door can be deadlocked by key. While deadlocked, the keypads will not operate the lock - code entry is disabled entirely until the cylinder is unlocked again. That gives a keyholder absolute after-hours control: secure the space at close without touching the codes, restore keypad access at open. Note the cylinder is a lockout control, not an entry override - the key cannot open the door on its own; for keyed entry override choose the BL5771MGPROECP. Cylinder not supplied - specify a standard euro profile cylinder sized to your door through Terry's, keyed alike or master-keyed on request.

Code Required to Exit - No Free Egress From Inside
Full keypads sit on both faces, and the inside lever will not operate the mortice until the correct PIN is entered - and while the cylinder is deadlocked, no code works from either side. Confirm this arrangement complies with the fire egress and building regulations for your doorway before purchasing; see exit paths on double-sided locks. If free inside egress is required, choose the single-sided Borg BL5001.

Code Change Is a Bench Job - Tumbler System, Keypad Removal Required
This model uses Borg's tumbler-based code system. To change a PIN, that side's keypad comes off the door: remove the 4 red screws, carefully lift the cover plate (springs attached), hold the C tumbler depressed, and use the supplied tweezers to reposition the red (coded) and blue (uncoded) tumblers. Up to 2,048 combinations per side, each side changed independently. It is a fiddly job the first time - read the bench method step-by-step and the traps to avoid before starting. Because the key lockout disables codes without changing them, many owners find they change codes far less often on this model.

Independent Coding Chambers - Different Codes Each Side
Each keypad has its own mechanical coding chamber. Both sides can share one code, or each side can run a different code - a shared entry code with a staff-only exit code, for example.

Free Passage Function (F Button) - Independent Per Side
During business hours either side can be set to free passage: enter the code, rotate the lever, then press F while the lever is rotated - that side becomes free-turning without needing the code on each use. To return to locked mode, rotate the lever and press C until an audible click is heard. If free passage should never be available, the F tumbler can be removed from that side's coding chamber during a bench code change (a replacement F tumbler is available if it is ever wanted back).

Internal use
The BL5050SC is a single-finish, internal-grade model. For external or coastal doors, the tubular-latch BL5051 family offers external grade and Marine Grade Pro variants.
Borg Back-to-Back Range Compared
Every model below puts a keypad on both sides of the door, all fully mechanical with no batteries. The differences are the lock format, the key function, the code change method and the weather grade.
ECP = Easicode Pro on-door code change. The BL5050SC is the only model in the table with the euro mortice format and the key lockout function - and the only one where a key can disable all code access without touching the codes.
Accessories and Spare Parts
The BL5050SC shares the 5000-series keypad platform, so keypad-side spares carry over. Tubular latches and the Lockwood 3572/3582 adaptor kits from the wider 5000 range do not apply to this euro mortice model and are deliberately not listed. Spare-parts depth is a core reason to buy a supported platform - see spare parts vs hardware store imitations.
Euro cylinders (keyed to differ, keyed alike, or master-keyed), additional tumbler sets and spring service parts can all be arranged through Terry's. Spare coded (red) and non-coded (blue) tumblers ship in the box.
Full Specifications
Dimensions
The BL5050SC uses the same BL5000-series keypad body on both faces of the door - the inside unit is identical to the outside unit. The euro mortice case sits inside the door edge.
Back-to-back keypad and lever - 177mm H x 48mm W, 26mm body depth, 115mm lever, 89mm total projection. Full-width drawings including the euro mortice case in the Dimensions tab.
Frequently Asked Questions
What is the key lockout function and how does it work?
The mortice lockcase has a standard euro profile cylinder cutout. Fit a separately sourced euro cylinder and turn the key: the bolt deadlocks and the keypads will not operate the lock from either side - all code access is suspended, without changing or removing any code. Turn the key back and keypad access is restored instantly. Without a cylinder fitted, the lockout function is simply inactive and the lock runs as a standard code-only BTB unit.

What is the difference between the BL5050SC and the BL5051?
Two things: the lock body and the key function. The BL5051 drives a 60mm tubular latch - a simpler bore-through install with external and marine finish options. The BL5050SC drives a euro mortice lockcase - a more substantial body morticed into the door edge - and adds the key lockout via euro cylinder. Choose the BL5050SC where the mortice format is specified or where a keyholder must be able to disable keypad access; choose the BL5051 for the simpler install or an external/coastal position.

How do I change the PIN code on this model?
It is a bench job. Take the relevant keypad off the door, remove the 4 red screws, carefully lift the cover plate (springs attached), hold the C tumbler depressed, and use the supplied tweezers to reposition the red (coded) and blue (uncoded) tumblers. Each side is changed independently. Test the new code at least five times before rehanging - the full procedure is at the bench method guide, and read the traps first.

Can each side have a different code?
Yes. Each lever keypad has its own independent coding chamber. Both sides can share one code, or each can be set to a completely different code during the bench procedure - and the free passage function is engaged and released per side too.

Can I reverse the handing on site?
Yes. Units ship factory set for right-hand doors. To change to left-hand: remove the rubber grommet at the base of each keypad handle, use the included hex wrench to remove the grub screw, rotate the handle 180 degrees and refit. Handing is determined from the outside of the door - right hand means hinges on the right. Background: understanding door handing in Australia.

Additional Information
Set the Codes Before Installation:
The tumbler system can be coded with the keypads on or off the door, but the bench is far easier. Set and verify both side codes before mounting - know the current code, work with the door open, and test five times per side.

Euro Cylinder Sourcing and Key Management:
Have the cylinder supplied and fitted by a locksmith who can confirm the correct length for your door thickness, key it to differ or keyed alike, and optionally fold it into the site's master keying system - Terry's handles all of this. Keep lockout keys restricted to authorised holders, and if a key is lost, replace the cylinder rather than hoping.

Mortice Installation Note:
The euro mortice lockcase requires a mortice pocket cut into the door edge with the 240mm faceplate recessed flush - a more involved installation than a tubular latch, typically needing a router or specialist drill guide. Verify the door construction suits morticing before specifying, or book the install through Terry's.

Fire Door Installations:
When specifying for a fire door, confirm every other item of hardware in the assembly is fire rated and compatible with the doorset certification - the rating depends on the doorset tested. The BTB configuration requires code entry from inside, and the key lockout can suspend code exit entirely - confirm both against the emergency egress requirements for that doorway with your certifier; see what is actually compliant on apartment fire doors.

Change Codes Often? Consider the ECP Back-to-Backs:
The tumbler bench method suits a set-and-forget code - and the key lockout means many sites never need to retire a code at all. But if codes must genuinely rotate (holiday lets, high staff turnover), the on-door Easicode Pro BTBs turn the bench job into a 30-second key turn: BL5051MGECP or the marine BL5051MGPROECP - background at why ECP matters.

Key Lockout and the Euro Mortice
Is the key lockout the same as a key override?
No - and the difference matters. A key override (as on the BL5771MGPROECP) lets a key open the door when the code is unknown. The BL5050SC's key lockout works the other way: the key cannot open the door, but it can deadlock it so that no code works at all. Override is a way in; lockout is a way to shut access down. Sites wanting both should look at the BL5771 for entry override, or run the BL5050SC with strict lockout-key control.

What euro cylinder do I need, and can it join my master key system?
A standard euro profile cylinder sized to your door thickness - a 60mm (30/30) cylinder suits most doors in this model's 35-54mm range, but confirm the length with your locksmith before buying. Any reputable euro cylinder brand fits the profile cutout, which means the lockout key can be keyed to differ, keyed alike with other doors, or integrated into the site's master key system. Terry's supplies and keys cylinders to order.

Do I have to fit a cylinder at all?
No. Without a cylinder the lock operates as a standard code-only back-to-back unit and the two supplied escutcheons dress the cylinder position on both faces. The lockout capability simply waits until a cylinder is fitted - which can be done at any later date without disturbing the lock.

Why choose a mortice lockcase over a tubular latch?
Three reasons: the case is a larger, more substantial body morticed into the door edge; the bolt carries saw protection (a hardened anti-saw element, marked A on the case drawing in the Dimensions tab); and the euro profile cutout is what makes the key lockout possible at all - a tubular latch has nowhere to put a cylinder. The trade-off is a more involved installation. The format decision in general is covered at latch vs bolt formats.

The trade-off is a more involved installation. The format decision in general is covered at latch vs bolt formats.
What is the smart way to run the lockout day to day?
Treat the lockout key like an alarm code: last one out at night turns the key, first one in turns it back. Staff keep using the same PIN codes all year - the codes never need to change just because the building closes. If a lockout key is lost, replace the cylinder (a five-minute job on a euro profile) rather than re-coding anything.

Codes and Code Changing
How does the code entry actually work - is it like a phone keypad?
Not quite. This is a purely mechanical coding chamber: each keypad holds one code, and the digits are pressed in any order - the chamber only cares that the correct set of buttons is depressed. Press C first to clear any half-entered attempt, enter the code, then turn the lever.

How long does a tumbler code change really take?
Allow 15-20 minutes per side the first time, including removal and refitting. The steps: keypad off the door, 4 red screws out, cover plate lifted carefully (springs attached), C tumbler held depressed, tweezers to move the red and blue tumblers, plate back on, five successful tests, then rehang. The honest time comparison across Borg's methods is at how long code changes take, and the method itself at the Borg standard tumbler system. Remember: the key lockout means you rarely need to change codes on this model at all.

What are the classic tumbler code change mistakes?
Dropping a tumbler (work over a tray), losing track of which tumblers came from which slots, coding the two sides differently by accident when they were meant to match, and rehanging without testing. The rules that prevent a lockout: know the current code, work with the door open, test five times per side. Full trap list: bench method traps.

What are the spare red and blue tumblers in the box for?
Red tumblers are coded (that button becomes part of the PIN), blue are uncoded. The spares let you lengthen or shorten a code. Additional tumbler sets are available through Terry's, and the free-passage F tumbler is sold separately - see spare tumblers explained.

Can multiple people have their own codes, and is there a record of who came through?
No - one active code per keypad, no user list, no audit trail. That is the honest trade-off of every mechanical digital lock against an app-based system: see what these locks will not do and mechanical vs smart compared. The compensation here is the key lockout - access can be suspended entirely without touching a code.

Fit and Installation
How involved is the mortice installation?
More involved than a tubular latch: a mortice pocket is cut into the door edge, the 240mm x 24mm faceplate is recessed flush, the euro cylinder position is drilled through, and the keypad through-door prep is drilled to the template. A router or specialist drill guide makes the pocket straightforward on timber; verify the door construction suits morticing first. The keypad drilling prep is on the drilling template (PDF), and Terry's installs across the Gold Coast if you would rather not cut the pocket yourself.

Which spindle do I use for my door thickness?
Two spindles are supplied (80mm and 90mm). The rule: door thickness + 30mm = minimum spindle length, because 15mm must seat into each keypad body. Use the longest that fits, and if cutting is needed, cut from the inside handle end only. The 8mm square drive is the common Australian standard, compatible with most leading lock brands.

Is a code-to-exit lock allowed on a fire door?
The lock is fire rated to AS 1905.1-2005 (up to 4 hours, doorset dependent) - but fire rating and egress compliance are separate questions, and on this model the key lockout can suspend code exit entirely. Many exit paths require an unimpeded single-action exit. Confirm the specific doorway's egress requirement with your certifier before ordering; see exit paths, fire door certification, and why passage functions are not a fire-door fix.
The lock is fire rated to AS 1905.1-2005 (up to 4 hours, doorset dependent) - but fire rating and egress compliance are separate questions, and on this model the key lockout can suspend code exit entirely. Many exit paths require an unimpeded single-action exit. Confirm the specific doorway's egress requirement with your certifier before ordering; see exit paths, fire door certification, and why passage functions are not a fire-door fix.
Why choose a mechanical lock over a smart lock for this job?
For an internal secure room the mechanical case is simple: nothing to charge, nothing to pair, no firmware, and the key lockout replaces the "disable user" button an app would give you. The honest comparison is at the realities of electronic door locks and Ch 16 mechanical vs smart.

Range and Spares
Where does the BL5050SC sit in Borg's back-to-back range?
It is the euro mortice member of the BTB family - the only one with the key lockout. The BL5051 is the tubular-latch equivalent (with external and marine finishes), the BL5051MGECP and BL5051MGPROECP add on-door code change, and the BL5771MGPROECP adds keyed entry override. Borg's naming decoded explains the suffix system.

I want a knob instead of a lever - is there a BTB for that?
Yes - on the tubular-latch platform: the BL5101 knob/knob BTB and the BL5151SC knob/lever hybrid. Neither offers the euro mortice or key lockout - the BL5050SC is the only BTB with those. Note knobs are harder to operate with full hands or limited grip; the lever remains the accessible choice.

Which parts are actually replaceable if something wears?
The keypad-side parts carry over from the 5000-series platform: the keypad unit itself, the scar plates, the gaskets and the F tumbler - see the Accessories table. And because the cylinder is a standard euro profile, the lockout cylinder itself is a commodity part any locksmith can replace or re-key in minutes. That serviceability is the gap between a supported platform and a hardware store lookalike.

Is this heavy duty enough for a busy commercial doorway?
No - it is a light-to-medium duty lock for internal doors. For genuinely relentless traffic, step up to a true heavy-duty platform: the Borg BL7701, Lockwood 3572DX (itself a mortice-format mech-digi) or the dual-keypad Carbine CDL7200 KDSC. Guidance at Ch 16 commercial use.
