Driver's Door Lock

I’ve searched this forum and found one topic mentioning the drivers side door lock failing. My problem is a little different than their issue however.

The door does not unlock from the FOB or the Proximity Sensor. However, if I put the key in the door, it will manually unlock and I can get in no problem. So the lock itself is at least physically functional still. When I get out of the car, the FOB locks the door every time and I get the security beep.

So my issue only seems to be with remote unlocking…every other function of the door and lock still works perfectly. I’ve also scanned the car with OBDeleven and see no codes in the Central Unlocking section.

Any ideas where I should start first? Any help is greatly appreciated!
