2003 Explorer XLT. Driver's door lock switch does not lock, only unlocks all doors. The key fob switch works on all doors. Broken switch?

Not sure if lock has solenoid or electric motor, but either way, can you hear clicks or any prominent sounds from the door whilst trying to unlock it? you may need to put your ear on the door, if no sound, then wiring needs to be checked, then motor or solenoid, if you do hear similar sounds to the other door then the mechanical part of the lock mechanism has failed and may require a kit or replacement.

Broken wire at door jam where door pivots.

possible bad button on key fob.unlock button good lock button bad .get a new clicker you can program it yourself ....put key in ignition turn back and forth 10 times while holding the unlock button on remote.that should work

Hi, if all of the locks on your Mercedes fail to open (or close) first check your key fob to make certain that its battery is working. Replace the worn out battery, if necessary. If key fob is working, you may have a faulty key fob, which can be repaired or replaced by taking it to your dealer.
If just one lock won't open on your Mercedes, then the problem may rest with broken wiring, a bad solenoid, or perhaps with a blown fuse. Check your fuse box first to determine if a blown fuse is keeping the lock from working. If so, replace the fuse.
You likely have a shorted door lock actuator, which you can replace with a new unit for the lock that is not working. If a door unlocks, but will not lock again, then replace the door switch.

Besides there is not OBD II 888 code, i have never heard or seen it before...

If the key turns in the lock, but does nothing, then the linkage has become disconnected or broken. The key is mechanical to the lock and the lock has a electrical switch to operate the central locking unit. Could be a simple broken clip from the lock barrel. Hope this helps

check the wiring going to the driver door switch. Check where it goes into the door and check for a pin push out in the door switch connector.

you may need to replace the door locking actuator, they do tend to go bad over times. does the driver side door lock automatic when using the lock button on the driver side. if you can lock and unlock the driver side door with a switch, my guess would not be the locking actuator, it might be in the remote locking module.

The key fob is the remote. But the remote type that works like a key. The remotes that you just need to carry on you to start the car or truck. That is a Key Fob.

Thanks Jay!

Unfortunately, This is a very common problem with Ford Explorers! Ford replaces the locks when it encounters this issue. I managed to unseize my passanger door and tailgate lock, but the drivers door lock is broken beyond repair. You can purchase new remotes for your explorer and program them very easily. Just google ford key fobs...

I have an A4 and did this to re-program my key:

1. used the key to start the car...then turned it off
2. put the key in the driver door (door closed)
3. pressed the lock button on the key fob once
4. turned the key to lock the door.

This is basically the steps in the owners manual, but the car must be started with the key first, and the key must be in the door lock before pressing the lock button.
