DISPATCHSame Day Before 11am
PIN Code (Both Sides)The Borg BL5051MGECP is a fully mechanical digital lock in a back-to-back lever/lever configuration with Easicode Pro on-door code change. Both sides of the door carry a full keypad and lever - a code is required to operate the door from either direction, giving controlled access in both directions. Each keypad has an independent coding chamber, so each side can run its own code.
The chrome-plated external grade finish resists corrosion in normal weather conditions, making it suitable for sheltered external doors - but it is not rated for coastal or saline environments. For the same back-to-back ECP lock in marine grade construction, see the BL5051MGPROECP. The lock is fire rated to AS 1905.1-2005 (up to 4 hours depending on doorset), accepts doors from 35mm to 80mm thick, and is cycle tested to 100,000+ operations. It belongs to the Digital Mechanical Locks range - browse the full Borg, Lockwood and Carbine mechanical digital lineup or the Borg brand profile for context.

Code Required to Exit - No Free Egress From Inside
The inside keypad requires the correct PIN before the lever operates - there is no free-turning inside lever. Confirm this arrangement complies with fire egress and building regulations for your specific application before purchasing. Exit paths and mechanical digital locks explained. If you need free egress from the inside, the single-sided Borg BL5001 has a keypad outside and a free lever inside.

External Grade - Weather Resistant - Not Coastal
The chrome plate external grade finish provides corrosion resistance in normal weather conditions and suits sheltered external doors. It is not suitable for coastal, beachside, or saltwater-adjacent environments. For a marine grade back-to-back ECP lock (1,000-hour salt spray tested, 316 stainless internals), see the BL5051MGPROECP. For how the brands compare on corrosion, see corrosion resistance in Lockwood vs Borg vs Carbine.

Easicode Pro - On-Door Code Change
The PIN can be changed with the lock installed. Insert the code change key over the code change button, rotate 90 degrees clockwise and hold, press C to clear, enter the new code, confirm, then release. No lock removal required. The 5000-series ECP procedure differs slightly from the smaller Borg chambers - see the 3000/5000-series ECP steps in the Changing Codes guide, or download the BL5000 ECP User Manual (PDF). Code change can also be permanently disabled per side using the included deactivation plug.

Why does this lock need a code from the inside?
The BL5051 is the back-to-back version of the BL5001. Where the BL5001 has a free-turning inside lever, the BL5051 carries a full keypad on both sides - the code is required from whichever side you are on, controlling access in both directions. If free inside egress is a requirement, choose the single-sided BL5001 instead.

Can each side have a different code?
Yes. Each keypad has its own independent coding chamber. Both sides can share one code, or each can run a completely different code. The free passage function also engages and disengages independently per side.

How does the free passage function work?
Enter the correct code, rotate the lever, then press F while the lever is rotated - that side becomes free-turning without needing the code each use. To return to locked mode, rotate the lever and press C until an audible click is heard. See passage mode explained, including why free passage must not be left engaged on a fire door. If passage will never be used, fit the included deactivation plug behind the F button.

Is the BL5051MGECP suitable for coastal or beachside locations?
No. The chrome plate external grade finish handles normal external weather but is not rated for coastal or saline environments. For coastal sites, specify the BL5051MGPROECP - the same back-to-back ECP lock in Marine Grade Pro construction with 316 stainless internals and 1,000-hour salt spray testing.

Additional Information
Spindle Selection for Your Door Thickness:
Two spindles are supplied (80mm and 90mm) - use the longest that fits. Rule of thumb: door thickness + 30mm = minimum spindle length, since 15mm must seat into each lock body. A 50mm door therefore needs at least an 80mm spindle. Cut from one end only and never shorter than necessary - a short spindle can slip under door slam and lock users out.

Chrome Plate Care and Servicing:
Wipe the keypad and lever surfaces regularly with a damp cloth. Apply a light silicon-based lubricant to the lever and button mechanism periodically - avoid oil-based lubricants, which attract grit into the chamber. Annual procedures are in the Borg Servicing Guide (PDF).

Codes and Code Change
How do I change the code, step by step?
With the door open, enter the current code. Insert the code change key over the code change button in the top centre of the keypad, rotate it 90 degrees clockwise, then press and hold. Press C to clear the old code, press the digits of the new code, then press every digit in the new code once more to confirm each is set. Release the key pressure, rotate back and remove the key, then press C (or turn the lever) to finalise. Test the new code at least five times and confirm the latch withdraws before closing the door. Full illustrated procedure: the 3000/5000-series ECP steps and the BL5000 ECP User Manual (PDF).

I changed the code and now it does not work - what happened?
The most common cause: C was not pressed between clearing the old code and entering the new one. The chamber is then set to a combination of both codes - if the old code was 1234 and the new one 6789, the live code is 12346789. Enter the old and new codes together, then run the change procedure again from the start. If the lever free-turns after a change, the new code was never set - repeat from the key-insertion step.

Does the order I press the buttons in matter?
No. The chamber is non-sequential - a code of 1234 opens with 4321, 3214, or any other order of the same digits. This is standard mechanical digital chamber behaviour. Over 1,000 combinations are available per keypad.

Can the inside and outside keypads run different codes?
Yes. Each keypad has a fully independent coding chamber. Set both to the same code for simplicity, or run different codes - for example a widely shared code on the inside and a restricted code on the outside. Each side is changed separately using the same ECP procedure.

We have lost the code - can it be recovered?
Yes, but the unit must come off the door. On the back of the keypad are ten portholes showing blue and red indicator lines - press C first, then read which portholes show a red line closest to the centre: those digits are the code. The porthole diagram is on page 6 of the BL5000 ECP User Manual (PDF). Note the code before refitting. If neither side has a known code and the door is locked shut, contact a locksmith - there is no key override on this model.

Can I stop other people changing the code?
Yes. The accessory pack includes an on-door code change deactivation plug. Fitted into the marked hole on the back of the keypad before installation, it permanently disables on-door code changing for that side - the unit must come off the door to re-enable it. Useful in shared facilities where only management should control codes.

Operation and Free Passage
What is the correct way to open the door day to day?
Press C first - this clears any buttons a previous user may have part-pressed - then enter the code and pull the lever down, away from the door edge. Release the lever and the unit resets and relocks behind you. The same sequence applies on both sides.

How do I set the lock to free passage so no code is needed?
Enter the correct code, rotate the lever, and press F while the lever is rotated. That side is now free-turning - anyone can operate it without the code. To relock, rotate the lever and press C until you hear an audible click; the chamber resets and the code is required again. Each side engages and exits passage mode independently. Background reading: passage mode explained and when passage mode makes sense.

When should free passage NOT be used?
Never leave passage mode engaged on a fire door - the door must be able to latch and the lock must control it (why passage mode and fire doors do not mix). It is also unsuitable on pool barrier gates, which must self-latch at all times. If passage will never be needed, fit the included free passage deactivation plug into the slot behind the F button before installation - the function is then permanently disabled for that side.

Why would anyone want a lock that needs a code to get OUT?
Controlled egress: preventing unaccompanied exit from secure yards, memory-support facilities, staff-only rear doors, or compounds where a reach-over defeat of a one-sided keypad is the risk. If your situation only needs entry control, the single-sided Borg BL5001 keeps a free lever inside - see when double-sided control is the right call.

Installation and Handing
The lever points the wrong way for my door - can I reverse it?
Yes, on site. All units ship preset right-hand. To change hand, remove the grey grommet on the side of the keypad handle to expose the grub screw, remove the screw with the supplied hex wrench, refit the handle facing the correct direction, and tighten the screw back in. Repeat on the inside handle. The handing diagrams (door configurations A through D) are on page 1 of the user manual (PDF).

Which spindle do I use, and can I cut it down?
Two spindles are supplied (80mm and 90mm) - always use the longest that fits. Rule: door thickness + 30mm = minimum spindle length, because 15mm of blade must seat into each body. A 44mm door needs a 74mm minimum, so use the 80mm. When fitting, angle the blade toward the top opening edge of the door. Never cut shorter than necessary - an over-trimmed spindle can slip out of position if the door is slammed, locking users out.

My door is thicker than 80mm - can this lock still fit?
Standard fixings suit 35-80mm doors. An XL fixing kit extends coverage to 85mm - contact Terry's before ordering if your door is in that band. Beyond 85mm, this lock is not the right product.

My door frame is narrow - will the standard latch fit?
The standard 60mm backset tubular latch runs about 80mm deep behind the faceplate and fits a typical 100x50mm frame comfortably. For narrow stiles, a 28mm backset latch (BLS275000) is available separately, and a 70mm backset latch exists for deeper setouts. Measure before ordering. Latch formats generally: latch vs bolt explained.

What should I check before final fitting?
Three checks from the manual: (1) enter the factory code from the code card and confirm the lever rotates down and returns under spring pressure, twice; (2) confirm the inside handle rotates freely and springs back; (3) press the latch bolt end and confirm it springs out freely. Change the factory code before or after fitting - but always test it five times with the door open.

Weather, Fire and Suitability
Can I install this at a beachside property?
No. The chrome plate external grade finish resists corrosion in normal weather but is not rated for coastal or saline environments - salt air will attack the plating and internals. For coastal sites, use the BL5051MGPROECP - the same back-to-back ECP lock in Marine Grade Pro construction with 316 stainless internals and 1,000 hours of salt spray testing. Decision guidance: do you need MG Pro? and how the three brands compare on corrosion.

Is this lock legal on a fire door?
The BL5000 series is fire tested to AS 1905.1-2005, up to 4 hours depending on the doorset. Two qualifiers: every other component in the assembly must also be fire-rated and compatible with the doorset certification, and the code-to-exit arrangement must satisfy the egress requirements applying to your building - see exit path rules and fire door certification explained. When in doubt, confirm with your certifier before specifying.

What does the corrosion guarantee actually cover?
The chrome-plated external components are guaranteed to resist corrosion in normal weather conditions for up to 1 year. Coastal or saline exposure is outside its scope - which is exactly why the marine sibling exists for those sites. The general 12-month manufacturing warranty runs alongside it (see the Warranty section on the main page).

How much traffic is too much for this lock?
The BL5051MGECP is cycle tested to 100,000+ operations and rated for medium to heavy usage. On extremely high-traffic doors - a main entry cycling hundreds of times a day - specify a genuine high-traffic heavy duty lock with a servicing schedule: the Lockwood 3572DX, Borg BL7701, or Carbine CDL7200LL-HD. What separates the tiers: heavy duty internals explained.

Maintenance and Troubleshooting
What routine maintenance does it need?
Wipe the keypad and lever with a damp cloth to clear dirt. Periodically apply a light silicon-based spray to the lever and button mechanism - never oil-based lubricants, which draw grit into the chamber. Annual procedures are in the Borg Servicing Guide (PDF). Quality internals are the reason genuine trade locks outlast hardware store lookalikes - but only when serviced.

Annual procedures are in the Borg Servicing Guide (PDF). Quality internals are the reason genuine trade locks outlast hardware store lookalikes - but only when serviced.
The code will not work even though it is correct - why?
Almost always a part-pressed button from a previous user. Press C firmly to reset the chamber, then enter the code again. This is why the C-first habit is worth teaching every user. If the code still fails after a C reset, run the lost-code porthole check to confirm what the chamber is actually set to.

Is there any way in without the code?
No - this model has no key override, which is part of its security story: no cylinder to pick or bump. The trade-off is that a lost code on a closed door means a locksmith visit. If key override matters, the BL5700 ECP keypads in the same family carry a built-in cylinder (covered in the user manual), and the Carbine CDL7200LL-KDSC-HD offers dual-keypad control in the Carbine range.
