Release button works but the door does not open
The fault may be the lock, relay, power supply, cabling, door alignment or a mechanical issue in the door or frame.

Door release, electric strike and maglock repairs
When the intercom call works but the door stays locked—or a controlled door will not secure—the fault may be electrical, mechanical or alignment-related.

Door will not stay locked
We check the lock hardware, power, controller output and alignment. A closer or warped door can create an entry-system symptom without being an electronics fault.
Commercial safety interfaces
Commercial access-controlled doors must be planned around the building’s escape and fire strategy. We identify where a competent fire-alarm or door specialist must be involved rather than bypassing safety controls.
Questions before you enquire
Common questions
Do you repair both fail-safe and fail-secure locks?
Yes, subject to the door, system design and safe access. The correct replacement must match the intended operation and building requirements.
Can you link a controlled door to a fire alarm?
Potentially, but the design must follow the building fire strategy and be coordinated with the responsible fire-alarm contractor where required.
