: Drivers Door Not Unlocking with key FOB

2005 STS

First time posting but I have benefited a great deal (and saved a lot of $) reading this forum - Thanks!

Anyways, I was hoping someone can advise on my most recent troubles. When I attempt to open my drivers-side door (with my key FOB in my pocket), the drivers door will not unlatch. All of the other doors unlock but for some reason, the drivers door will not. The key FOB has new batteries and the car still recognizes the FOB. Exiting the vehicle is not a problem. I am currently stuck manually using my key to open the drivers door. I assume this is some sort of sensor but I was hoping someone here might have an idea how to fix this... I would really like to avoid the cost of bringing my car to the dealer.

If the other doors open by pulling the handle the actuator which pops the door has failed and needs replaced
