I had an electronic safe once, it did come with emergency access keys. One day I needed to get into it in a hurry and, of course, the batteries were dead. In my panic I could not remember where I had hidden the emergency keys. Two quick smacks with a hammer and I was right inside. So much for security.

As much as I'd like the convenience and speed, I'm sticking with old-school key or combination locking safes for now on. I'd rather invest my money on security than fancy technology that is likely to fail again at a critical moment.
