Maglock Not Releasing

Troubleshoot magnetic locks that will not release from access control, intercom, REX or emergency release devices.

Start here: Do not replace hardware until power, cabling, configuration and the correct wiring path have been checked.

Step-by-step diagnosis

Confirm the symptom

Check whether the fault is constant or intermittent and whether it affects one device or the whole system.

Check power and cabling

Verify power, polarity, PoE, battery, terminations and patching.

Check configuration

Confirm IP address, zone, reader address, relay mapping, app registration or recording settings as relevant.

Compare with the diagram

Use the related diagram to confirm the device is wired to the correct input, output or network path.

Quick checks

  • Check whether lock power is being interrupted correctly.
  • Test REX, break-glass and fire release paths.
  • Confirm controller relay mapping and lock output timing.
  • Check for residual magnetism or door alignment issues.
