  • Testing the new key is a final check to confirm that the re-keying process was successful. It ensures that the lock will function as intended and provides peace of mind that only the new key can operate it.

  • Reinstall the lock: Once the new key works properly, reinstall the lock on the door by securing it with screws. Make sure it is aligned correctly and operates smoothly in the door frame.
