where did you get the key from? was it programmed to your vin/vehicle? or did you get something off the internet and not a dealer?

[ChanceG8X]

No I didn't get it from the dealer is that something I'll have to get done?

Yup.

They have to be matched to your vehicle. That ability is closely guarded by BMW.

Gotcha thank you very much will have to do that was very confused why it wasn't working.

Yeah, I had to bring my registration (proof of ownership) with the VIN to my dealer parts department and they ordered me a key. I skipped their "programming" and synced it myself.

I got a new genuine HUF remote and was unable to teach it in using ISTA +. I went through the process, but it fails. ISTA Says I might be able to do it manually, but I am afraid I am stuck buying the key from Bimmertech or the dealer at $500+

If it were that easy, I could steal a car and buy a key on Ebay and teach myself.
But it's not that easy.
You need special software to teach a used / new key.

Well, you need a working key first to wake the car up, so that would not work.
