My friend Erik uses a heavy cable and a padlock to keep someone from walking away with the bikes on his car rack. He recently lost the keys to one of the racks but wanted to keep the cable, so he needed to cut the lock. Being an American Lock purchased from a locksmith we figured it’d be quite a task to get it apart, but since it ended up to be a Series A30 aluminum body lock it was much easier than we’d anticipated.
Using a heavy duty Hilti reciprocating saw he first tried to cut the hasp, but the hardened steel was only polished shiny by the saw blade. He then cut into the lock body and ended up severing the pin which holds the lock together. It was then easy to remove the core and use a screwdriver to actuate the lock mechanism, releasing the hasp. With a set of picks I was then able to disassemble the core and remove the pins and springs. A quick tug on a small brass ring with needle nose and the ball locks for the hasp were free and the lock was completely disassembled.
