last month, i came home for winter break, and left the key to my yale padlock in my dorm. over the whole break, i was not able to pick the lock, and i noted having trouble feelingthe second pin . Today when i got back, i tried the key, and it didnt even fit. i am positive it is the correct key because i only have one yale lock, and it worked before i left. looking in the keyway reveals no obstructions, and i am really confused what is keeping the key from fitting.
my only guess is that something got in the lock and jammed it up. i tried some silicone, but the problem still persists. any ideas?
