Keys will not program to lock/unlock

Sat Feb 08, 2020 3:04 am

As per the title I have tried on many occasions now and found a few problems that I thought would be the cause the latest being the door lock switch in the centre console was busted but seeing that it is a simple momentary make switch it should not be the cause. I notice that in one of the diagrams the air bag (SRS) is connected to the EWS and I have an Air Bag light on which cant be turned off because there is a fault (apparently). I don't see why this would prevent me programing the remote but maybe it does.
Has anybody got any suggestions as to why and what could be causing this and where to start looking.
The doors do lock and unlock with the broken switch when I hold it together and the keys do work I tried them on a friends E46.
T thought I had solved it when I realized that I was holding the lock button down and pressing the unlock button 3 times but when I did it the correct way it still didn't work.
They are both new keys I bought of fleabay and programed them to match the EWS with an AK90 and they will start the car.
Also I cant the key to lock or unlock at the driver's door lock, I am thinking that this is most likely where the problem is.
I have been to newtis and have looked through my Bentleys manual but both just tell me how to do things when everything works OK and if it wont work take it to a dealer.
Damn Bentleys is useless sort of says if car wont start fix it and road test. :headbang:

My brother inlaw had a similar problem with his 5 serieis touring which turned out to be the diversity antenna in the car mounted in the rear spoiler.
First time BMW changed it under warranty, second time an BMW Specialist fixed it, it seems they suffered from water ingress. The specialist took it apart cleaned it re-soldered some joints put it back together and sealed it, no problems in the last 4 years (cursed him now).

Worth checking out as the X5 is a 5 series on steroids, check realoem for the antenna location and newtis.info for wiring diagrams.

Good Luck
