I've got a couple of american combo locks, (they look just like master combo locks) and of course shimming it to get it open would be easy, or figuring out the combo by finding the 3rd number and doing the math, but they actually have a keyway in the back of the lock that I never got the key for,(probably becaused my work supplies the locks for our lockers) but I don't think my work gets the keys either! When an employee quits or gets fired and if the company doesn't know the combo they just cut it off with boltcutters.
The funny thing is, I can pick this keyway on the back of the combo lock in about ten to fifteen seconds!
So now when they need to remove a lock from an ex-employee's locker, they just ask me and I get to keep the lock too!! (bonus)
But if they don't supply a key with the locks, are the keys only for locksmiths or whats the deal?
Just thought I'd ask.
