A short answer is no. The safe's keypad is just a power source that communicates the code to the lock inside the safe door. Your combination code is stored inside the lock body. The lock body is housed, protected and secured inside the door. The lock is protected by relockers which will secure the safe if a burglar attempts to punch through your lock. Should a burglar place a different keypad on your safe the lock cannot be opened without your safe combination. The lock retains the last programmed code you entered regardless of whether or not the battery or keypad has been replaced.
