My driver's side door does not lock when I press "lock" on the keyfob. I have to lock it manually using the key. It also won't unlock when pressing "unlock" on the fob either. The passenger side locks and unlocks fine. The lights come on and everything. What could be wrong? Can someone help me out? Thank you!!

 

You have an 07. Take it in under warranty. Probably an actuator if the passenger side works fine.
