Approach your alarm panel and enter the master code, which is "1", "2", "3", "4, "5". If you have already reprogrammed your master code and are reprogramming your code for a different reason, you need to enter the master code you selected when you first installed your alarm.
Listen for the beep after you input the master code. Within five seconds of hearing the beep you need to enter the master program address, which also comes with your lock when you purchase it. The master program address is "AL", "1", "AL".
Press the keys for your new master code within five seconds of entering the master program address. Make the code any five digits you can remember, without making them obvious and easy for thieves to figure out.
Push "AL" and enter the new master code one more time to validate it. From here you should hear six beeps and the lock should relock itself. Test your master code to make sure the process worked correctly.
