Unless I see the lock I can only say that I would have 2 levers at most. It will be warded, possibly bulleted.
Indeed call a lockie, he should be able to open it with wires. And in theory a master locksmith should be able to measure all the depths, gages, and impression the lock to make a key for you to open the lock. A bit of metal work for the pro, a bit of a blush for the newbie lockie.
