RE: Keyless ride: using the 'emergency' key - 3

I'm glad I've found this article!
I'm having exactly the same problem with a new plastic key. I'm also having a new Scorpion Datatol tracker fitted under warranty next week. I'll bet that's the root of the problem.

Thanks for the updates and advice from all.

I will add the following, after a recent trip to my dealership, enquiring about a trade in, which I declined.....anyway.

Part of the discussion was about the keys I had - original keyless, extra bmw key so I don't snap the fob, and the grey key.

When I advised I "carry it with me in a pocket in my coat" the saleman advised very few customers do this despite the back-up use it provides.

Many trade-in chats resulted in a "I think it is at home somewhere with my documentation" response.

Looks like some breakdown emergencies could have been resolved if you just carry the key at all times, which is the point really.

Tested it today and despite being on a keyring it works if pushed into the seat the 'wrong way round' from owners manual advice.

Just ensure it is pushed almost out of sight as partial fitment doesn't get the working result if 50% of the key is visible.

Worth checking at home you know it works rather than at a 'non start' issue following a food/fuel stop etc.

I could answer my own question by experimentation, but will the fob work passively like the spare key?

In every keyless car I've experienced, the fob can be held against an RFID antenna in the car and that will allow starting if the fob's battery is dead.

yes, as mentioned by several people in the recent "do I change my fob battery at 50% thread"
