    Sometimes when I turn my truck off, the door lock on the driver side doesn't unlock. I have a security system in it, and the door lock automatically when I turn the ignition and unlcok when I turn it off. Sometimes they just move a little and don't come up. When I use the key to unlock them, its fine. i think something is wrong with the linkage. I greased it really good when I had the door panels off last, but I don't know whats wrong...anyone?

    check your security systems electrical connections and also see if there is any binding inside the door might be just enough to stop the auto looking but not enough to affect you using the key

    Sounds like the solenoid/door lock motor is sticking. Not sure of the fix, sorry, but that symptom has happened in the past with one of my earlier rigs, actuated by the alarm. The alarm only "tells" the door lock solenoid/lock mechanism to fire.

    Mine did this after changing lube in the locks/latches. Use a good lithium grease on the actual lock mechaniasm.
