The code is entered, lock does not open, lock emits 2 braps (long beeps).
The code is entered but Lock does not open and the Keypad emits 2 braps.
The 2 braps indicate that the lock is in “Penalty Time”. Penalty time occurs when 4 or more incorrect codes have been entered. Penalty time can also occur if an error was made while performing a combination change. This feature safeguards against unauthorized entry into the safe.
Leave the battery(s) in the keypad. Do not touch the keypad for 5 -15 minutes. Earlier model 6120 had a penalty time phase of 15 minutes. After 15 minutes (max) the lock will reset itself and the correct code can now be entered to open the lock.
