I have 12-14 locks on the compartments. I hate having to fiddle thru 3 or four keys to get to to the right key.
Keep in mind that I can open any compartment faster with a large flat blade screw driver than you can with your key. These locks keep honest people honest, but will not prevent a thief from getting in.

It won't do MACH 2, but I can get a sandwich and take a pee.
