Key Coding to Car

[///Mpatient]

Does anyone know how to code a new Key to your car.
2008 E92 M3 Manual if that matters.

Sorry didn't use the I'm on mobile and it sucks ass.

My dealer sent me a new spare key for my car and provided the following instructions:

1. Insert fob into dock
2. Start car
3. Run for 15-20 seconds
4. Turn off car, eject fob
5. Step out of car and check lock/unlock and trunk

Worked for me. I think I confirmed functionality again after the program by starting the car and checking transmission engagement.

Hope this helps! :-)

Thanks, stupid battery in the key was dead.

FAIL!!! Everything is good to go. Thanks for the post.

I felt like a moron, why isn't my comfort access package working on the new key?
