I have an 97 E36 328 coupe and only got one spare key with the car but two Sigma alarm fobs. My key is an old style BMW key with the crappy little light thingy integrated into it.

I have strange issue… I bought a spare diamond shaped key blank (from later E46 and E39 with boot and door lock buttons *of course this key is empty inside) from eBay and had it cut. This key will open the doors but cannot start the engine. ???


I disarm the alarm using the Sigma (which also unlocks the doors) slot it in the ignition and when I twist… nothing. I checked the key in all of the locks and it releases the steering lock ok but it still doesn’t fire the motor.

Anyone know why?
Does the original key have a chip or something in it?
