anyone experienced EWS issue? car doesn't want to start

The ring is the antenna for the EWS vehicle security system. All BMWs from 01/95-on have one of the versions of the EWS security system.* These systems center around a transmitted code, from a chip in the key, and the control unit matching the code.* The ring antenna reads the coding in the key. If*the key, antenna ring or any other part of the system*is corrupted or damaged, the engine will not start. replacement antenna ring.*I would assume that the snap clips, on your current one, are weak.

okay. connected everything back today and same thing. I guess next thing that I'll do is to find the relay for EWS and measure voltage there to see if it's getting voltage.

what is the "snap clip" that you mentioned? so, you're suggesting that besides EWS unit(either bad or not aligned with DME), it could also be a bad key or antenna ring? I hope I have a spare key to rule out the key issue. Have been searching for it but just don't know where I put them away.
