I would start by digging through realoem.com to work out what might be there. Bear in mind that the security unit (EWS) is almost certainly coded to the engine management AND the keys, so you'll have some fun there for a start. Beyond that, it really depends what is broken or missing. Have you any idea at all why the system doesn't work? Without analysing the problem you might spend days swapping stuff about and find it still doesn't work.
there is no red light on console and no stickers on the windows with 'bmw or alarm' or a siren in the engine bay
i am buying a ECU which requires the EWS and key chip from the same person so i would have them installed on my car so its just what else would be required
alarm module - wiring - siren - door locks??
