Hey I have never done it but I bought a tubular lock pick for $40 and can pick one of those locks and steal everything in under 30 seconds and I did it to my front door in 15 seconds it’s crazy what you can learn on line
You need to put your machines in a better location. No outside locations, hotels, or malls. These are top theft locations after schools and colleges. A broken vending machine will not make you money, and cost you thousands. It is better to find a secure small business location and make less money than to find a great location that has constant theft and causes the machine to need damage repairs due to vandals.
I wish I could get out to this guy but it’s the style lock he is using. He needs to quit using the tubular style lock believe it or not it’s the easiest one to get through
