CAUTION: A User Code is used to unlock the door while a Mastercode is a password for making changes to the lock features.
1. Make sure the lock is unlocked and the door is open. 2. Enter your existing Mastercode - for new install, default is 0-0-0-0. 3. Press the lock button. You will hear one beep. 4. Press 5. 5. Press the lock button. You will hear two beeps if successful. If you hear three beeps, it was unsuccessful. Repeat from step 1 slowly.
For a new installation, this will delete the default User Code 1-2-3-4. For subsequent instances, this will delete all User Codes in the lock.
Now the lock can only be operated by the key and turnpiece until a new User Code is added in step B.
