I asked Jim Gosnell about drilling when I had one that wouldn't open. He said emphatically DO NOT attempt to drill out one of these. It won't work and will just make it harder for any other attempts.
If it is not recessed, what about using a right angle grinder and grinding it down until it falls through the door?
I have locks like that!!!
I am also coming to see you thrusday...I'll bring my grinder
I think I have a set of medico cam locks that I can lend you until you get your new locks in. I do prefer the LAI locks over the medicos for the bays.
