Nissan Repair Questions? Ask a Mechanic for Answers ASAP
I have seen this couple times actually, but everytime I have seen it your still able to get into the car using the key on the drivers door. You simply pull the handle almost simultaneously as you turn the key to the unlock position.
The last case I had like this, the 5v lock signal pulse was coming form the key cylinder switch in the drivers door. It was sending a continuous lock signal so anytie you unlocked the door they locked back immediately. Another time I had a drivers door lock actuator causing the issue. I actually assumed that was the case the last time before testing and replaced a door lock actuator for no reason, only to find it still happening. After testing the wires with the meter, I found it to be the key cylinder switch.
Hope this helps.
