Meh.
YouTube Lockpickinglawyer, and spend a few minutes making some picks.
Spend a little time looking at the stuff that passes for "Security" and you will come away understanding that even most of the really expensive locks, are mostly keeping the Honest, the lazy, and the stupid, from going where they damn well please.
Watch a few Deviant Ollam videos on so called security in commercial spaces, as well as hacking RFID pass badges, and you will wonder why anyone bothers to put locks on the doors...
Gut the lock you took off. Take the pins and springs out of the keyway, and keep using it, without ever needing more than a pointy stick to open it. Or a screwdriver. Or an actual key. But without the worry of having to find the 'right' one!
