Having owned our boat for several years now we finely decided it was time to get the safe open. We have tried numerous times with out any luck. Our concern is with a boarding someone is going to request we open it. I have researched numerous sources, safe vendors, manufacturer, and several safe crackers on how to open this safe without drilling it. One gentleman even did some research while traveling Europe visiting manufactures and their representatives. No one was able to identify the source of the lock. U-tube even suggests hitting these smaller safes on the top to open them. Problem is it's mounted in the a wall with no access from behind. It is a Fichet-Bauche Confident safe with an electric lock. We have the manual and have tried everything suggested. Any ideas?
