Just looking for confirmation of problem/solution.

Using FOB, front driver's door won't lock/unlock. It also won't auto-lock when the car is put into motion.

I can lock/unlock using the key in the door lock.

I'm familiar with taking the door on/off so I'm pretty sure I can replace the actuator myself or I could have the professionals do it.

Am I missing anything?

Looks like the part (5121840253) is $210.



Thanks to the forums for having so much information readily available.
