I had the same problem. We finally located where the batteries were hidden. They were below the keypad, There is a silver, plastic cover that slides to the right to expose the 4 AA batteries. Hope this helps you.

No, the key is the only way to open the safe should the batteries fail or you forget the combination.

Combination will not open safe

I'm sure you have opened it by now. however, when the safe goes into lockout mode. You must wait for the lockout period to end. That length of time is customizable, so I can not say how long it will be. Most likely 10min to 1 hr. Then just enter the code normally.

Suddenly we can't open our Church Safe. It has worked fine for almost 2 years. We have replaced the batteries with new fresh ones but still can't get the electronics to allow us to open it.


The safe can lock up under determined conditions. Since safes are security anti-theft devices, in case they do not open, they can only be accessed with the help of the manufacturer.

Please, call Mesa Live Technical Support. The operators are available Monday - Friday 8:00am - 4:30pm (Pacific Standard Time)
The phone number is toll free. Here the number: (800) 490-5624.

Using Mesa online page you can also identify the model and download the manual. It is better finding out the safe model before contacting the Mesa by phone, so to speed up support operations.

Providing safe cracking infomation is prohibited.

You have two choices, call a locksmith who will open the safe and record all details and log it with the police, or have the key posted to you. Fixya is not permitted to supply details of safe entry for legal reasons
