If the result of this does not yield any results continue to step 2.
Passenger door lock not working.
An inoperative power door lock can be caused by the switch solenoid wiring problem or mechanical problem within the linkage of the affected door.
If the door lock actuators fail they will disable the power door lock feature from working.
This issue also indicates a bad lock actuator.
The key fob battery is dead.
Pop the window and door lock switch panel off the door handle.
Follow lead wire to the door lock actuator.
The battery is likely dead and needs to be replaced but the remote s may also need to be.
If not then you may have a blown fuse.
While the key is in work the door lock manually up and down while using the auto lock at the same time.
To unlock the doors the switch reverses the polarity of the voltage applied to the solenoid.
If your locks arenĂ¢ t working replacing the battery in the key fob could solve the issue.
If your key fob doesn t work yet the manual door lock button does it is time for a new key fob battery.
I googled different articles the very next day and found this article is very helpful.
It gave me some insights on what to check on my vehicle for the passengers side interior door lock switch that doesn t work properly.
If any wiring is damaged replace them.
To lock the doors the switch provides voltage to the two terminals of the solenoid.
This battery is located inside the key fob and can be accessed by opening the fob.
Once you have it opened locate the battery and replace it.
In order to open it you will squeeze on the sides of the fob to pop open the front and back.
This will require the driver to use the key to lock or unlock the doors and can disable the power door locks completely for vehicles that do not use a traditional key such as newer luxury vehicles.
The door lock works in only one direction.
If the lock tries to move then it is a frozen lock mechanism.
Step 3 work the lock manually.
Locks work from the switch but not the remote.
Last night i noticed that the passengers side interior door lock switch was not working properly.
If one set of switches can control the windows it s likely the switch on the opposing side that needs to be replaced.
The windows work off the passenger side switch but not the drivers side or vice versa.
Remove switch panel and inspect wiring.
If they do work the problem is most likely in the door lock solenoid.
Unplug the door lock connectors and inspect to make sure nothing stands out.
