Key fob will not lock driver side only.

I realise it's an obvious suggestion but have you tried a new battery in the key fob? You could also check the fuse controlling the door lock motors.

Ignition key works the manual door lock:
You get out the original fob... pull out the (metal) key... insert it into the single lock slot under the drivers side door handle...
and twist like an old fashion key lock.

Just replacing the battery in a key fob should not require any reset! If the power door locks work using the remote or key then it could be the switch is faulty!

Could be your driver door lock mechanism that is going bad , since the other door are working, it cannot be the fob. I would try to change the driver side door latch mechanism.

First things first...replace the cheaper part first, the battery. It that works, great! If not, then you may need a new key fob then have it programed to your system.

Ah change the batteries in the key fob if they are dead it wont work.

First thing first-change battery in fob-most jewelers can do this as well as dealers-takes more power to unlock than lock

were talking about the key fob battery.right?? try holding both the lock and unlock buttons at the same time while pointing the key fob at dashboard/drivers side door area.give it at least 10-20 seconds and see if that resets it.

sounds like the solenoid that locks and unlocks is bad or the rod came off of the linkage in the door
