Asked in Consumer Electronics
You you have an electronic safe with dead batteries?
Most cheap safes have an over -ride key for just such a situation, it is usually hidden under a removable cover plate or even under the keypad which on some safes is removable. Most higher grade safes have the battery under the keypad which can be changed without losing the code fromthe safes mamory. I suggest taking a picture of the safe and and emailing it to your local safe expert (many locksmith say they are safe experts but are not) and asking his opinion.
