Driver's power door lock inop with key

[175K911]

I think I know the answer, but thought I'd seek the guidance of those who may have had the same problem before I dig in.....

'86 911 with power door locks. Putting the key in the driver's door lock, it'll lock the passenger side, and will cause the driver's door button to go down momentarily, then it pops back up again. So I need to reach across from the passenger side and manually lock the door. Key will properly unlock both doors.

So the door lock actuator is working to unlock, and trying to work in order to lock the door.

Door lock actuator?

TIA

Lock and unlock using the knob/button inside the car and then try it again. May be a stuck actuator.
