I attempted to unlock my door with the factory keyless entry code. It did not work for whatever reason but that is not the issue. After attempting to use the code, now the key fob will only unlock and lock the passenger and the two rear doors. (Everything except the driver door) The unlock and lock button on the driver door in the interior does the same thing. Every now and then after the truck sits, the buttons on the key fob and door will work, but not often. Does this sound like a door lock actuator issue? If not, what other things could it be?
