My key fob has not been working for some time, i have to use the key to lock and unlock.
up until recently when you unlocked the car at the drivers door, it would would re-lock instantly, unlock a seccond time and it stays unlocked.
locking was a single action.
Now, when you unlock it is a single action, locking instantly unlocks, you have to lock it a second time for it to stay locked. this is a problem if my wife drives the car and forgets to 'double' lock the car.

I have had problem with the immobiliser when the key fob first stopped working, got some support from BMW and was told that if i got in the car, closed the doors, turned the key to on but did not start the car and waited 20 min or so, that the haz lights would flash and the immobiliser would turn off. this did happen but was a couple of years ago and the details are a bit fuzzy.

Any suggestions...
