2003 Honda Accord Keyless Entry and Driver's Side Door Lock

When I press the button on my remote to lock the doors the drivers side door will not lock. If you attempt to use the actual power lock button on the inside of the car three doors lock--all except for the drivers side door. I have to physically push the lock down in order to lock the driver's side door.
If you try the keyless/remote to unlock the doors none of them will unlock but the drivers side slightly moves. I won't say it even comes up at all--you see it move/wiggle as if its stuck. You hear a sound as if its trying to unlock, but its like it is jammed. If you put the key in and turn it then all doors unlock.
Not sure what part I need. Thanks in advance for your help.
