I have always been a combo guy, hell I don't know how many times I have opened a S&G combo lock in a 20 year Naval career. After many questions to the business, I would give it a try. If I don't like it or have problems, they said they could switch it back to a tumbler lock. We shall see. Here are pics of the old safe.
The new safe.
After 3 hours of moving stuff over, rearranging the safe 2 times, everything is now home and in their place. My girls are able to rest until they are called upon, but they did enjoy being held and touched.
