keyfob not unlocking or locking car

[jbaker1006]

hi im new the this forum so if i looking in the wrong place apologies??

we went out a few days ago and our x5 e70 would not open with the key fob? opens all doors and boot with the metal key but alarm sounds when opening the door.

we dont have comfort access on the car.

i have checked all the fuses for the locking system all are fine.
i have tried the re programme steps from the internet - key in ign on hold the unlock button and then press the lock button etc

has anyone come across this before? and how was it fixed?

also can anyone share on how to code the interior lighting to have led bulbs, i have the ipna software from the e46 we used to have is there a way to use this to resolve the key issue?


thanks any advise would be much appreciated
