The key fab will lock and unlock all doors except the drivers door and the lock botton in the car on the drivers door will not lock or unlock the drivers door either. How do I fix this problem?

Why won't key work in door? Most likely not used? Spray wd-40 in door lock and insert key moving it back and forth in a sawing motion. This will usually free up a sticky lock and you can then turn it. Most lock out companies use a long metal rod. They will pry back the top of the door where it meets the roof and insert a wedge to hold the door slightly ajar and then insert the rod which has a hook to catch the lock and unlock it. A coat hanger unfolded will usually do the trick with a little patience. If not, the only other way is to disassemble the inner door panel ( usually causing damage ) to get the door open

door reciever or lock has issues
did you scan the car first.
does the receiver put 12dc to the unlock solenoid.
if yes the solenoid is bad.
if not the receiver has issues. (check connections first there)

The problem is possibly a ground failure into the computer

(door lock actuator)all doors have one in them, they weeken, and sometimes work to open, and some times to lock, or not at all. only fix is to replace each of them as they go out, usually cost abt 20 to 40 bucks a piece

Order a new keyfob from the dealer and have them program it to your car.

some how lever to the lock unit came off , need to open the interior panel of the driver door and put back lever to the lock unit. It should work.

Open the driver door with the key for the ignition?

Remove the door panel and reconnect the plug going to the front driver door lock or, if you can hear the motor trying to engage the door lock cam when you press the lock/unlock remotereconnect the door lock lever bar

The electric door actuators are bad/broken so they need to be replaced its a common problem
