All other doors unlock. If driver's side door is open and I hit the unlock button on driver's side door, the locks start to lock and unlock about 3 times. Do I need to reprogram my keyless remote or is this a more serious issue that needs to be handled by mechanic?

This is most likely a door lock actuator issue.

You need to start with unlocking the door with the key to open the door.

Then remove the door panel and start checking the voltage when pressing the unlock button.

Here are a couple guides that will help with this:

Basically we need to see if there is voltage coming from the junction block for this actuator. If it is then the actuator needs to be replaced.

I also attached the info from the manual that takes you through the testing for the actuator.

Please run through this info and let us know what questions you have. Thanks
