How to troubleshoot central locking.

It is this whole assembly called the Central Electric Module:

Vauxhall key fob re programming

and a few other links:

Cassini Spacecraft Dives Between Saturn and its Rings

its a 2007 model and as such can have the key fob reset with dealer diagnostic software ,wouldnt have thought removing a fuse would de-actrivate the factory immobilisor though

you need to reset the alarm/immobiliser after replacing batteries,

sounds like its time for a new fob, try useing the key to unlock the door this should shut down alarm, if its the key fob chip your talking about then hope you have a spare if not, depending on the year may need to reprogram a new key fob.

Not a solution just another problem...Lost my car fob key, have a replacement key no circuit. As I open door, sets off immobiliser like above for20 mins. I had someone look under the glove compartment but that got me no joy. How can I (non techy) resolve this so I can drive my baby home...Vreg Avensis1.8 model?
many thanks

will your passenger door open with the key and is it just one side that your windows are not working or both. if its just one side it might be your regulator motor in the door thats not working if its both it might be your central locking pump usually in the boot. however if both of them are working fine it could be that your key needs reprogrammed however i think the 1st 2 are more likely to be the problem.

If im not mistaken,your car should have an alarm reset/override.Below the steering column,on the dash should be a slot where you put your remote transmitter to deactivate the alarm.If that works,you then need to have your remote checked and coded by a vw dealer.Good luck.

just unplug the immobiliser unit. its behind the glove compartment for rhd models.

with any BMW they have their problems, one is the central locking/immobilizer, the central locking is linked into the immobilizer and vice versa, the immobilizer takes it signal to disarm from the central locking and the ignition key ring. (chip in the key) if one of these starts to play up it has loads of consequences this being one of them. they all need to work together for the system to work properly. you would need to read the alarm and immobiliser codes using an ob2 tool that can detect them, and find the fault some problems it can be the drivers door sensor in the lock this is the main door as its drivers side and it controls all other doors on the central locking. if the switch is worn in any of it movements the system will not know the door has been opened, this does not work on the interior light as that is a switch in the door frame. the door lock is lock unlock and deadlock with key with remote fob its also arm disarm alarm and immobiliser. i have seen in some models there is a sensor auto lock so when you walk away with the key the doors lock automatically all lease parts work together. any one having a problem can cause no signal to be sent to the others in the system to start engine .
