 Driver side door won't open, from inside and outside
Hey guys. Today I woke up to a pleasant surprise that my driver side door just refuses to open. I don't have a remote for my car, so I unlock it by turning the key in the door. However as of right now, the key refuses to turn in any direction from the outside. I unlocked the car from the passenger side and tried to open the door from the inside but still nothing. The door lock plunger moves when I pull the inside handle, but thats about it. It's been really frustrating and I've been reading a ton of articles but none match up to a problem on both the outside and inside. Any insight or advice? Thanks |
