Symptoms
- Unlock works sometimes, fails other times
- You hear the motor but latch/deadbolt doesn’t retract fully
- Door opens only if you pull/push the door
Fix steps (most effective order)
- Replace batteries (fresh full set).
- Test with door open (10 cycles).
- If it fails closed: adjust strike plate so the bolt/latch moves freely.
- Check door sag and weather seals (binding).
- Re-run calibration/handing if your model supports it.
Do not keep forcing repeated attempts — fix the friction to prevent wear.
