I would get one of those little mirrors on a telescoping rod, a small LED light, and a coat hanger. Go through the coin receiver hole. Illuminate the back of the lock, use the mirror to guide you, and see if the bent coat hanger can push on the back of the lock. If this works, it will save you a lot of grief. If it doesn't work, you can always drill out the lock. Make sure the lock is popped out in front first!
