Electronic Locks

There is wide selection of electronic safe locks installed across the UK, and whilst the manufacturer may be clear from insignia on the keypad, it is not always as easy to narrow down the firmware level – which defines the available features, such as number of users, audit facility etc.

“A wide selection”

The photos shown below are a few examples of many types of electronic safe lock in circulation. Please contact us for more information.

LA GARD electronic safe locks

The keypads above, and any similar with the LG, LA GARD or possibly KABA logo are fitted with LAGARD locks. As the keypads are interchangeable, it may not always be possible to define the specific lock installed, without viewing the actual lock body.

Bolt type

The bolt type is important, as it defines how the lock interacts with the boltworks of the safe. 

If access to the lock body is not possible, some questions to the user may help to define the bolt type:

  • Does the keypad turn to open? If not, and if there is not a small knob fitted, the bolt is likely to be a swingbolt.
  • If the keypad turns, the bolt is likely to be a deadbolt, which is further indicated by the user needing to turn the keypad again to close, possibly in conjunction with safe handles.
  • If the user does not need to turn the keypad again to close, and it feels as though the keypad wants to spring back into position, the bolt is likely to be a latchbolt. Latchbolts are less common as they are not certified to EN 1300 standard.


The firmware is described in a black lined box either somewhere on the security label, or occasionally embossed into the lock, and may be one of those listed below.

CodeLock firmware
3802 / 3803LG Basic
39eComboGard Pro 39e
33eDiscontinued. If time delay is required, replace with a 39e, if not, an LG Basic will suffice
LGAAuditGard 66e
Ser44LG Master of F-Series. Discontinued

Identifying by operation

A combination of the elements below may help to narrow down the options:

Code length: Most LAGARD locks have 6 digit codes. If the code is 8 digit, where the first two digits are the user ID 01-31, it is a Supra.

Timelock: Only the TL11 has the facility to be programmed with timelock tables, whereby for certain periods of the day (Overnight for example) the lock is “Timelocked” and inaccessible)

Dallas Keys: If the lock uses Dallas keys, it can only be an AuditGard 66e.

Users: By attempting to add or delete user numbers with the Manager code, it may be possible to eliminate certain locks:

Dormakaba electronic safe locks

Axessor Series

The Axessor USB, Axessor CIT and Axessor IP range replaced older locks such as the Kaba 525, Questor and Axessor

Auditcon Series

Auditcon keypads, like LAGARD, are interchangeable. They are generally fitted with deadbolt locks, and if there is no Dallas Key reader, it is most likely to be a 52 or T52 model.

Single user
Users 1-20
(Supervisors IDs 1-3)
Users 1-99
(Supervisor IDs 1-5)

Bolt type: Whether the lock is a deadbolt or slide bolt (Similar to a swingbolt), can be ascertained by the normal lock responses after a valid code entry:

Deadbolt: 1 slow green flash

Slidebolt: Continuous green flashes for approx.. 5 seconds

Code length: If the user codes are 6 digits in length, the Auditcon is a 52/T52. The difference between these is that the T52 includes Time Delay as a feature. 8 Digit codes (2 Digit ID and 6 Digit PIN) are used for the 252 and 552.

Additional features: If time lock is in use, the model is a 552
