I have a pre-LCI 2017 M240i and it only came with one key fob, I'm guessing the previous owner kept the 2nd one. I ordered the same keyfob from aliexpress and made sure the numbers matched. How do I program this to my car? I've read that the dealer has to program it and then I'll have to sync it with my car and I've also read I can do it myself, but as of yet have not had any luck. Can someone give me a definitive answer?
