I have a safe with an S&G lock system on it. Originally it was electronic but I think it acted up a couple times. I got real paranoid it wouldn't open so I replaced it with a mechanical dial lock. I miss the convenience of push buttons but I trust the dial lock more.

You can replace your electronic S&G lock with a S&G mechanical dial if your safe is like mine. It's a Browning safe. S&G made the lock systems so that they 'bolt' right in the same mounting holes. If they sold your safe with both electronic and dial lock I'd bet that it is the same way. The conversion kit was less than $100.
