Key fob not locking/unlocking doors

[TJM]

So recently my key fob won't lock the drivers door when I push the lock button. It will lock the others, but it doesn't "beep" and the drivers side door stays unlocked. I have to manually lock it, then if I hit the lock button again it will beep and the headlights will go off like normal.

Also the unlock button won't unlock the drivers side door but will unlock the rest.

I changed the battery but that didn't help. No idea what's going on here. Any advice?

Do you have another fob? Does it behave the same way?

There is a history of door lock actuator problems that is mentioned in a few threads over the years. A search for those threads will get you info on how to replace them, get the door panel off and where to get replacements. Your symptoms appear to indicate one of the actuators has failed while the others are working.

There is a thread by mbumpus11 from Aug 2017 on this issue. It's titled "Drivers door lock actuator repair step by step with pics" that should help.
