I can't see how this is for an E90 as the key I have is completely different. It does not turn, it's just stuck in the hole in the dash. I tried this several times with the hold unlock press lock 5 times etc. in several different ways, but no joy at all. It seems it is only works for cars with the type of key shown in the video. :-(

Thanks for this. My 2002 Z3 key stopped working. For the past year the remote usually only worked if grounded to the car. It stopped working altogether about a week ago. I replaced the fob battery and still no go. I've replaced the battery w/o a re-synch before with no issues, but I guess the fob had completely lost its paring. Glad I found your post. Thanks.

I bought after market keys from Amazon. Had one key cut and will manually unlock the doors and trunk. When re syncing the new key it will work the doors and trunk from the fob but it won't start the car. If I start the car with the orig key and shut it off then put the new key in it will start the car for only a short while. (minutes) I figure the new key is just running of the code from the old key in order to start it until the code goes poof from the ignition. Is there any other process I can try to get the new key to start the car all the time. It's a 2001 BMW 330ci...Thanks in advance for any assistance you can render.

Thanks for posting this. I'd like to add something that might be useful....if the reprogramming procedures above don't work, lock your car (using your key in the driver's door) and check to see if the fuel door is locked. If it is not locked as it should be, check fuse #53 in the right side of the trunk. If that 7.5amp fuse is blown, it will cause your key fob not to work.
