OK. Got the new fob, and was online this morning with Bimmer tech to code the fob to the car. The tech guy said everything went well, and told me the original key was activated and should work, too. But the CA still does not work. Neither the doors not the keyless start. He said there must be something wrong with something else in the system, and said to troubleshoot the antenna. I've done some searching, but cannot find out much info on how to do this. I've found other threads with systems other than the E89, but nothing specific for my model.

Can anyone help direct me to something helpful? TIA

Give this a watch, the last tip shows how to factory reset the car to it’s original settings.

Probably the best place to start with these sorts of things.

Downside is that you may lose the coding on the new key, can’t be sure on that, your original would still work though.

Wow. If it does the same as disconnecting the battery, it seems easier to disconnect the battery, lol

Yeah, possibly. I would imagine a reset may have a different effect, depends on the car, and how long the battery is disconnected for.

If you are troubleshooting electronic issues, knowing a reset is done gives you a jumping off point before trying other things.

Best of luck with it!
