A good design would have riveted the machine shut, ensuring the only way in was through the tamper-evident seals. At work today (I work in construction) I managed to remove a latch & lock system from a door without damaging either part. I manipulated the door hook with the padlock on and loosened the top screws, which gave me enough room to remove the top two screws on the door frame latch, which gave me enough room to remove the two screws on the door hook. I then removed the bottom two on latch by using the new upward-slack. I forced the latch section around until the middle screw became loose, angled the latch and slowly removed the centre screw. I essentially just broke into the customer's garage with no signs of forced entry. Had the lock been installed properly (IE no slack in the system) it wouldn't have been easy to remove it with no signs of tampering. However it wasn't installed properly. Incidentally, one of the easiest ways to solve this problem is to take a drill bit and to strip the head of the screws. This leaves only manually forcing of the lock to open it, which takes a lot of effort if you're using 3 inch screws through a proper stud.
