Well,i was going through my junk box when i found a chicago lock with key.So i inserted the key and it would not turn so i put my half dimond in there and jiggled the pins around just in case there were stuck.After that i put the key in and it still would not turn,So i put some graphite in there and slide the key in and out and jiggled it but it still would not turn.
I noticed on the key it reads(2135) and on the lock it has(H2133) so i dont know if these numberes have to match,Do they?
So is it some thing wrong with the lock or the key?
This is what my lock looks like
