What to do
- Replace the batteries with a fresh set of the correct type.
- Re-enter the code slowly and deliberately, confirming each button press registers.
- Check the manual for whether a confirmation or unlock button is needed after the code.
- Clean the keypad buttons gently to ensure each one registers properly.
- Try the manufacturer's backup or master reset code if you have documentation of one.
- Contact the manufacturer's support with proof of ownership if fully locked out.
- Avoid forcing or prying the lock, which can cause permanent damage.
