Door stays unlocked after unlocking
Wiring fix · updated 10/29/2026

If the door unlocks but then stays unlocked and does not lock again, the lock is usually wired the wrong way at the relay.
1. Check the wiring polarity. Make sure the + and − wires to the lock and its power supply are not swapped.
2. Check the relay terminals. Make sure COM and NC / NO are not reversed.
   • A lock that unlocks when it gets power (most electric strikes, fail-secure) goes on NO + COM.
   • A lock that unlocks when power is cut (maglocks, fail-safe) goes on NC + COM.
3. Fix the wiring, then unlock from the door phone or the app to test. The door should lock again when the unlock time ends.
