Updated Feb 9, 2026
Overview
Door and access issues usually involve alignment, latch sensors, or lock motor failures. Control access and reduce tampering.
Diagnostics
- Confirm the door closes fully and evenly.
- Inspect latch sensor and magnet alignment.
- Listen for lock motor engagement after close.
Resolution steps
- Re-seat door gasket and realign hinges.
- Clean debris around latch and lock components.
- Reboot and retest the locking cycle.
Preventive maintenance
- Clean latch weekly in high-traffic sites.
- Avoid overfilling shelves that block the door.
- Check hinge alignment monthly.
When to contact support
- Lock motor does not actuate.
- Door sensor fails after alignment.
- Repeated lock errors in the event log.
