It can be difficult to maintain the security of an in wall safe. You never know when someone like an auto locksmith might gain admittance to the room that holds such a safe. There might be an expert at auto locksmithing who needs to make some extra cash, and has chosen to work as a tutor. While tutoring your son or daughter, that local auto locksmith could possibly find a way to enter the room with the safe.
Perhaps your children are no longer in school. In that case, you should consider another possibility. What if a mobile auto locksmith were to befriend your son or daughter? What if he were then able to make his way into the room with the safe? You would have to keep an eye out for evidence that a team of auto locksmiths might manage to learn the combination to your in wall safe.
Here are examples of the things that you want to watch for. Look for any series of numbers that looks very much like the numbers in your combination. A locksmith/thief might have written the combination somewhere in the room, in an out of the way place. I one Persian movie, a thief put the combination on the wall, and then the daughter of the safe owner noticed that her date of birth had been written on the wall.
Still, that thief was not the one who broke into the father’s master lock key safe.No the real thief was someone who took advantage of the presence of a construction crew. He managed to sneak into the area of the construction. Then he opened the safe and hid its contents in the ceiling. Fortunately, the police caught him before he could make a withdrawal from his make shift “bank.”
