I have a mini U-lock from OnGuard.
The lock is not attached to the bike, so that's not a factor is this question.
I can see the locking mechanism jutting out partially into the key hole, which is preventing the key from being fully inserted into the key hole--it only can go about 1/2 in. How can I get the mechanism to go back in to place so that my key may be fully inserted? Or is it time to finally break down and get a whole new lock?
