JOHN DEERE LIBERTY SAFE MANUAL
Our gun safes have the option to be manufactured with an electronic lock instead of a manual key lock or dial. Learn more about upgrading your safe to an electronic lock by contacting your local Liberty Safe dealer. Liberty Safe uses high-quality SecuRam electronic locks for their safes because of their extreme reliability. This will ensure your safe can always be opened quickly, as is intended by equipping it with a reliable electronic lock. Liberty Safe recommends that you replace the battery in your safe lock every six to 12 months. The last thing you want when you go to open your safe, especially in an emergency, is to find out the batteries are dead in its electronic safe lock. Replacing your battery with a fresh one should resolve this problem for you right away. This is because there is not enough juice left in the battery to fully power the opening operation. However, when you try to turn the handle, you might find that the lock has not fully disengaged. After entering your combination code, you might still hear the expected beeps and clicks that happen as the safe's bolt disengages. If your battery is not quite dead yet, the lights or display on your lock could still light up. In fact, your electronic lock's memory can hold onto your codes for up to 10 years whether your battery is dead or removed. This is because electronic locks contain what is called non-volatile memory that holds onto the combination codes that you have programmed into your lock.
JOHN DEERE LIBERTY SAFE CODE
You can rest assured that once you replace the battery in your lock, your combination code will still be there. While it is inconvenient, being locked out of your safe because of a dead battery is only a temporary problem. But what if you go to open your safe and find that the battery has suddenly died? Will you be locked out of your safe because your code will be wiped out? Here is what happens when the battery on an electronic safe lock dies.

The nine-volt battery in your safe's electronic keypad lock should normally last between 8,000 to 10,000 openings.
