Do you know anyone that works for a utility like power or telecom or cable? Contractors too, because they might be driving older trucks. Some utility trucks had similar locks on their bin doors. Keys that fit one truck might fit another truck, as if there were only so many different locks made , rather than a unique lock & key for every truck. We found that a few different keys would often open locks on several different trucks. Might be worth a try before you start drilling holes.
