Don't think you can do that. You can certainly disable the alarm but that should not disable fob central locking operation as far as i am aware. Unless disabling alarm disables the fob. But there is certainly no stand alone disable fob function. Rick the pick may know more about it than i do.

It would seem that if the alarm is disabled, the central locking works fine from the key. Not tried it myself but read more than one thread where it's been done.Don't think you can do that.

Don't know Keith, can't see why disabling the alarm would disable central locking via the fob. Have seen plenty of cars that lock on a fob but don't have an alarm fitted. Unless on the Range rover they go hand in hand and are interdependent.

Correct. Tried it on mine.

+1 Looked through my BECM settings using my lynx and there was nothing in there to disable the central locking.

I did not say that it disabled FOB locking/unlocking, only that with the alarm disabled the key could be used with no problem instead of the FOB.

Just to reiterate. Someone said he had the fob disabled in the BECM and uses the key. There is no function to do this as far as i am aware. You can only enable or disable the alarm. Doing that must disable the fob central locking facility. So the alarm must function in the same way that the early BMW fob locking alarm system worked.

My fob definitely works with the alarm disabled in the BECM. Everything else works.
This is backed up by the Nanocom instructions:
Alarm: The alarm can be either enabled or disabled if required. Disabling the alarm prevents the alarm from arming and stops all audible and visual activity whenever the vehicle is locked or unlocked. It does not affect the immobilization.

Thinking about it, the Nanocom can trigger the locks. Could try that if you like?
I always stay away from that function because I'm worried the pulse might be too long and damage the lock actuator motors. I know someone who tried it without apparent damage though.

FOB still works with the alarm disabled, but they key can be used without triggering the alarm as the alarm is disabled.

Lock pulse length is controlled by the BECM not the nanocom.

There is a warning in Nanocom instructions not to leave solenoids energised for to long otherwise damage may occur. So i would think the Nanocom is controlling the voltage to the solenoids.

Interesting, I thought the BECM produced a one shot pulse regardless of the time either the FOB button is pressed or how long the input from any other source was maintained. Possibly from diagnostics it continually cycles, I will have to take a look.
If the above is not the case, it would account for the ease with which lock motors burn with a duff RF receiver, bad design, should be a one shot pulse not repeated until the input signal has been removed for X period of time.

IIRC when I had my lock issues there was only a single pulse between the outstation and the actuator when I pressed the fob. The motor was burnt out. Not sure if that would make a difference or not.
No problems since the new RF receiver was fitted.
I think maybe Saint was just speculating over whether the fob could be disabled or not. I think we've all agreed there isn't a setting.

Not the fob...the whole CDL itself....
On mine, the key in the door locks only the drivers door but sets the alarm...similarly, pressing either of the fob buttons will set/unset the alarm but not actuate any of the locks....so I was wondering if the CDL could be disabled or if I have a more sinister problem as I cannot detect a pulse from the outstation to the lock motor to cycle the locks...
Think the next step is to use diagnostics to cycle the locks to see if they respond...if they do, time to dig deeper...if they don't, lock motors burnt out....seems odd that all four would be burnt out but yer never know!!

I did this last Saturday.
On the Nanocom, testing the door locks is an ON/OFF thing, it leaves the locks energised until you press the off button on the Nanocom. It's all a bit terrifying because after pressing the off button, it takes about 10secs to update the Nanocom screen and actually de-energise the locks.
