Both Front Doors won't lock/unlock with Remote

[shevin]

I just bought this BMW X5 2003, and it didn't come with a master key, came with a buton-less key. which I had to manually lock the front doors by hand.

Previous owner said if I order a master key, it will be solved, today I ordered Master key from the dealer and they programmed it, but still both Front doors wont be locked by the remote.. the remote only locks/unlocks the rear doors. ( same with Lock button in the center console next to the emergency flasher)

Some forum search suggest lock actuator problem, but
I find it hard to believe that both lock actuators go bad at the same time .... could it be the previous owner unplugged the lock actuators ?
what do you guys think ?

If you can lock and/or unlock the front doors with the interior master door lock switch, then the door lock actuators are connected.

The General Module relays are know to go bad in these vehicles, not sure if the E53 has a GM5 or other GM module. You are dealing with a 13 year old vehicle and things do not last forever.

You may also have a combination of problems, maybe a bad GM relay for the drivers door and a bad passenger door lock actuator?

See www.bmwgm5.com for more info.

Thanks for answer, I can not lock/unlock the front doors with the interior lock/unlock button.

If the central locking button does not work, can you unlock the rear doors using the key in the drivers door lock cylinder?

The only reason I can think someone would have disconnected the door lock actuators would be because of auto locking enabled, this would cause the rear doors to lock??

But I would check all the fuses carefully to make sure none are blown and none are missing or in wrong position.

You could also pull the GM module and make sure all connectors are plugged in all the way, I do not recall if the door locks are separate connectors from the others. The www.bmwgm5.com site may have a connector diagram.

But either way seems like if you need to go after door lock actuators, you will need to pull the door panels and you will find out if they actuators are unplugged for some reason.

Good luck.

the key in driver, does lock the rear doors, but not the front seat.
where is the fuse for lock in x5 2003 ? and what should I look for in the BMWGM5 website.

windows work perfectly fine.
and I can lock the driver door with the rotating the key, and I lock the front passenger door by pressing down the lock on the door.

so, only thing doesnt work, is
not being able to lock the front doors with remote key, or with the center console lock switch.

You may be really experiencing bad door actuators. Do some cheap testing, apply power to them directly.

how can I apply power to them directly? and where should I apply the power?

can possibly both door actuators go wrong at the same time?

Since you just bought it, it is possible. One might of went bad, the owner neglected it, then the other failed. All speculation of course.

An auto probe is the best best to inject power into the plug of the actuator. You must first figure out your +/- wiring on the actuator harness.. If you don't have a probe, you can get creative with 2-wires from a 12v source. If that seems like a headache (especially if there's more that 2 or 3 wires on the actuator and you don't have schematics on it), You can also swap the rear actuator to the front, Obviously it will not mount to to the front door, but it should plug into the same harness. Try it on the passenger front door.
