Hello!
Ok so i bought my is220d on Saturday morning.
The fob and button on the door didn't work but the car has a separate fob fitted to work the central locking.
I checked the battery in the key and it was the wrong one so I've fitted the correct battery and now when i press the button on the door the key flashes as it should BUT doesn't open or lock etc.
Ive tried to add a new key but get no communication with the smart entry system, as if its been cut out for the fobs to be wired in any one else had this problem?
