Hey guys, first post here, but I recently picked up a 2002 4wd 4runner. So far, I love the rig but am trying to address some of the little issues that come with buying a 150k mile car.

The most annoying one is the drive side door lock. Here are the scenarios:

-I do not have a key fob. The truck only came with two keys with the responder. The previous owner said he has the stock alarm system disarmed. Not sure how this can be done. The security light on the HVAC controls blink, but there isn't a "Toyota Security" light to the left of the steering wheel
-Every door locks/unlocks when using the interior power door lock button, except the driver side
-When I put my key in the exterior door lock, I can turn the key to the right, but not to the left. This is the only way I can unlock the car
-When I do the above procedure in the passenger side, I can turn the key both to the left and right, and all doors lock/unlock properly, except the driver side.

Thanks for the help.

 

Bump. Is this an actuator and cylinder lock problem?
