I have a similar problem, My drivers side front and back work fine, it's my right side front and back that move but don't quit lock or unlock.
Each door has a motor that operates the door lock mechanism when the door lock button or the remote lock button is pushed. If the door lock moves a little but not enough to lock or unlock the door, then either the motor is not working fully or it is partially jammed, or the door lock mechanism is binding and the motor can't move it fully. Remove the door lock trim panel and check all the components involved in the door lock process until you find the problem.
I had the same problem in my 1999 Sub. The factory uses rivits to hold the door lock actuators in place. Over many uses the rivits elongate and the actuator travel is not enough to over come the longer distance. Try replacing the rivits with short screws. Short so they do not interfear with other stuff that moves in the door.
I think you have to push the 'unlock' button twice in order to unlock the doors.
You have to press the unlock button 2 or 3 times to get both doors to unlock no programming needed
FOB
unlock all of the doors, either on your key or from inside the car by pressing the unlock button manually. you have to press it twice to unlock all of the doors.
If you press the unlock button two times it should unlock all the doors.
Push the open button twice in quick succession, this should open the rest of the doors
If you have a newer model, with the remote unlock built in to the ignition key, press the button that looks like a trunk opening. This will open the tailgate but leave the other doors locked. Otherwise, press the Unlock button TWICE - this will unlock ALL doors, including the tailgate.
I don't want to sound simplistic, but you need to press the unlock button TWICE in quick succession. Just pressing it once unlocks the driver's door, the second press unlocks the other doors. Hope that helps...
To unlock the rear door ???just push the unlock button on the drivers side door on the in side and it will unlock all doors and the rear door also. then Just pill on the outside rear door handle and it will open., push the button 2 times to unlock all doors.
I have an 04 Durango Limited...and my key fob does in fact unlock the rear lift gate. You either have to hit the unlock button 2 or 3 times to get it to unlock the rear lift gate...but it should do it.....mine does. I think pressing unlock once unlocks the 2 front doors....twice unlocks the rear doors...and a third time unlocks the lift gate.
To unlock the passenger doors on a 2003 Land Rover, you can use the key fob by pressing the unlock button. If the fob is unavailable, insert the key into the passenger door lock and turn it to unlock. Additionally, you can also unlock the doors from the inside using the central locking switch located on the driver's door panel.
Hit the unlock button two times quickly. This will unlock the driver's door and then the passenger door. Sometimes I need to hit the button three times.
