- Wipe down the keypad surface with a dry cloth to remove dirt or moisture.
- Confirm you're entering the correct code, checking for any recently changed codes in the app.
- If it's freezing outside, warm the keypad briefly (like with your hands cupped around it) and try again.
- Check the manufacturer's app or manual for a keypad re-pairing procedure if it uses a separate wireless keypad.
- If the keypad still won't respond, try locking and unlocking with a physical key or the app to confirm the lock body itself works.
