I get the infamous automatic "lock then unlock" behavior and I would love to fix it. Once I do the double keypress override, all doors lock as they should. After cleaning/inspecting all door contacts, the problem remains. So now I am going through the system looking for clues. I have started to replace actuators one at a time, which brings me to my question:
When turned with the key, all door locks actuate the central locking system EXCEPT the rear door. I took this as a clue that the position sensor on the rear actuator or latch assembly must be bad. So I replaced the actuator and latch assembly with another (used). After replacing it, the problem remained. I then tested both position sensors on the old one and they were fine.
Sooooo:
1) Should the key to the rear door actuate the central locking system, or am I imagining that?
2) If the answer is yes, what else could the problem be given I am 99% sure that both the door contacts and position sensors in the rear door are fine.
Thanks!
