As far as I know, it was a programming option with the dealer installed security system. You have to pay the dealer to turn it on, and I think it only works with EWS cars. All I do is hit the lock button once, it beeps hit it again and it beeps 2 times, and once I do that I also can't open the gas filler door, and the interior door handles won't open the doors, and the alarm arms and starts the little LED flashing. If I hit the button 1 more time it chirps 3 times and unlocks the car. Dave __________________ Dave - PDX 1995 318ti - Active Black and Tan. 2005 330xi - Mtech 1 - 6spd - Orient Blue/Black |
