Garage gate fob stopped working after firmware update

After a vendor firmware update, roughly 40% of resident garage fobs stopped working. Same-day rollback restored access and the board added a change-management policy.

Residents began reporting fob failures the morning after a scheduled firmware update. Reports were consolidated on one issue thread so the vendor saw the scale immediately.

Timeline

  1. 2025-05-02 · Reports pouring in

    12 residents logged the same fault before 09:00; manager consolidated into one issue.

  2. 2025-05-02 · Vendor paged

    Vendor confirmed the firmware update as the likely cause.

  3. 2025-05-03 · Resolved

    Firmware rolled back; all fobs re-enrolled and tested.

Resolution

Vendor rolled back to the previous firmware version and re-enrolled every fob. The board now requires 48-hour notice and a rollback plan for any access-control update.

Lessons for other boards

  • Consolidate duplicate reports onto one issue — vendors respond faster when they see the true scale.
  • Require change-management approval for any vendor update that touches access control.
