The car in question is a '93 Pontiac Grand Am. The door lock is a very simple 1 sided lock and I tried to open it using a pair of auto jigglers I obtained. After I tried with the jigglers, the key does not turn the lock at all. I've tried looking into the lock to see if anything seems out of place, but I cannot really tell. The passenger door is now used to gain access to the vehicle using the original key.
Does anyone have any helpful suggestions about how to fix this? I was thinking of taking WD-40 and spraying it in the lock and working the key back and forth before resorting to pulling the cylinder out of the door (which I am not sure of a good method of doing so). Any tips you guys have for me would be greatly appreciated and if you think I need to remove the cylinder and rekey it, please give me advice on how to remove it.
BTW, the key still fits all the way into the lock and the keyway is not turned (which would indicate that some of the pins have been picked).
Thanks alot for your help!
