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. 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 lock should normally last between 8,000 to 10,000 openings.
