my remote key and drivers interior button will open driver door only, and will lock both doors.
any thoughts on why passenger door does not respond to command?
passenger interior button will not unlock door as-well.

Sounds like there is either wiring issue with the or an issue with the actuator. Does it unlock from the switch on the passenger's side?

 

no, does not unlock with passenger button either

 

update: my keys opened everything, truck doors etc when i purchased the car. the trunk stopped working with the key for some reason. i did not associate the problem with the door on the passenger side.
one day i forced the issue with the trunk key, it turned, and then my interior button, and double key to door worked fine.
conclude they all work together.
going to get some grafite, easy fix.
