What to do when a Liberty electronic safe lock's battery dies

As we mentioned above, if an electronic lock battery dies on a Liberty Safe, you just need to replace it with a new one.

Batteries are accessible from outside the safe. The battery tray is located either at the top or bottom of the lock face, inside the keypad. Slide the battery tray down and out of thekeypad or pull the lock face and exchange the old battery with a new one.

What about your code

And don't worry about your combination code. Even if the battery goes fully dead, the electronic lock will still keep the code you have entered by means of non-volatile memory.

Lock lights

There is also a case that a battery in the lock has some charge which is indicated by still lit up lights on the display. When you enter the combination, you will hear usual sounds and clicks that identify lock opening. But when you turn the handle, you might not open the door. It can happen because the battery charge is not enough to enable the opening. All you need to do is to replace the battery with the new one and open the safe.

The type of battery

When changing the battery, take into consideration what type of battery to put into the lock. Not all batteries are good for safes. The best option is a high-quality alkaline nine-volt battery, like Energizer, Duracell, Panasonic, GP, and Varta. Store brand carbon batteries may be of good quality and have the same voltage but they don't have enough amps to make the locking mechanism work smoothly. Thus, a safe owner may find themselves unable to open their Liberty gun safe even after they have replaced the battery.
