If it's your only RFID key you should do something about that. Valey key from the dealer may be the only cost effective option.

I know we've had this conversation before, but I'm getting forgetful. What's the part number I need for a valet key, where to buy it, and how much. Last time I searched, the keys of all sorts were unavailable from dealers, even.

I started to make plans to bypass the EWS, if/when my single key becomes unrepairable (probably when I next cut it open).

Wait a second, have I been thinking wrong about the ignition key situation?

If a non-battery-powered valet key will turn on the ignition, then it's the RFID chip inside that's doing the trick.

It's passive, being read by the ring antenna on the steering column, so my problem with intermittent starting (cranking) is not a key problem, but lies elsewhere.

Perhaps the chip is loose inside the diamond key shell, and sometimes is too far away from the antenna to be detected, or the antenna is starting to fail, or is it the switch itself? There's always a chance that the EWS module is giving up, too.

Just overthinking again.

i should've researched further, before ordering the cheaper valet key, but I thought it would come pre-programmed from BMW. I must've made the wrong assumptions, but I was following this advice, without questioning it:

So, now I guess I''l have to get a locksmith to come out to my driveway, and program the valet key? or wait until I get the fuel delivery system to work reliably. Either way, I'm screwed for now, and possibly wasted $90 on the valet key, instead of applying that money towards a diamond key.
