I was watching my cameras and some hoodlums looked like they were vacuuming out his car while the other was picking the lock on the vending machine. Just then he opened the door and took all the change and bills. Cops were called and all evidence was given to the police. We have plates and make/model of the car. Just a matter of time till gotten. However, he got into the lock very easy. By grinding off the tip of the barrel key that he had, his fit into ours and just opened it up. As long as the crooks barrel key is the same diameter as the one he is trying to get into, its no problem. He then puts bill dispenser back and the change bin back just like he found it. We are now changing to a regular key, as we are told they are alot harder to get into. Just an FYI if you have a barrel key.
