Coding a new key is not hard if you have the spare key, not sure what is needed to cancel old keys out of ECU, but surely it is only a software job ??????
This info is not from me
Hello All,
I searched and think this is moderately new - seen a few posts about replacing the battery or how to start the bike (Keyless Ride) with the emergency/wallet key, but I lost my original and only fob on the road while riding.
Here's how I programmed my replacement fob (from BMW) after I spent $160 for the new fob at the dealer.
1) Place emergency key at the antenna ring under the rear fender, and
2) Turn on the bike ignition at the push button - simultaneously.
3) Place emergency key outside of 2m from the bike (or farther).
4) While bike is on (doesn't need the engine actually running) - hold the new/replacement fob at the ring antenna and push the BMW logo button on the fob. Hold that button down until the lost key signal on the dash turns off. You are now good to go!
I have seen other stories (from RT folks) and was told by my own dealer, that the service charge for this would have been $50 at least.
