this is my problem too, ish.
i had an intermittant key fob, like it wouldn´t open the doors but would operate the imobiliser...sometimes it´d unlock the doors, sometimes not. right, new battery time i figured.. took the key to the key / watch shop, and he opened the key, said oh, i´ve got none of those, and put it back together. now it wont open the doors OR operate the imobiliser.
when you press the button the light comes on and goes off again in about 1 second, i´m sure it used to stay on as long as u held it in before?
i went to the main (st)dealer here in spain in my town and got them to change the batteries, the light on the key is now alot brighter... but still the problem remains.
i only have one key. i cant drive the car
anyone got any ideas?
