Access Control Door Not Opening?

A door that won't release on a valid card or fingerprint is usually a power, wiring or enrollment issue -- not a sign the whole system needs replacing.

The Reader, Lock and Controller Can All Fail Independently

An access-controlled door has several parts working together -- the reader, the controller, the electric lock, and the wiring between them. A fault in any one of these can look identical from the outside, so diagnosing which part failed matters before ordering a replacement.

Likely Causes

Why This Happens

The most common causes we find when diagnosing this fault.

Power Failure to Controller

Controller or power supply not receiving power.

Faulty Electric Lock or Strike

Lock mechanism itself has failed, even if the signal is correct.

Credential Not Read Correctly

Worn card, dirty sensor, or fingerprint needing re-enrollment.

Wiring Fault

Damaged or loose wiring between reader, controller and lock.

User Not Properly Enrolled

Credential added incorrectly or expired in the system.

FAQ

Common Questions

How do I know if it's the lock or the reader that's failed?

If the reader beeps/lights up correctly for a valid credential but the door still doesn't release, the fault is usually in the lock or wiring, not the reader itself.

Can one bad credential cause the whole door to stop working?

No -- a single bad credential only affects that user. If the whole door has stopped responding to everyone, the fault is in the controller, lock or power supply.

Is there a manual override if this happens during business hours?

Most systems can be fitted with a manual key override or request-to-exit button as a backup -- worth having if this door is business-critical.

Does Qyvea repair access control installed by another company?

Yes -- we assess the existing system first to confirm what can be repaired.
