All is good!!!

After rebuilding the door look cylinder - the central locking system started to work again. After that I was able to re-initialize the new key as well as the old key so I now have full remote control restored to my faithful X5!!! In the end I was able fixed the issue for less than 1/10th the cost the dealer wanted to charge me!


THANK YOU ALL FOR YOUR HELP!!!


Note: I had to use a different re-initialization procedure than the old simple one. I got it from "stearman22" at this BimmerFest post:

If you were reading along, you will see that the Key Initializing did not work for me and my car
I took it to the dealer/ majicion and it was done in under the time it took me to get that free moca java.

Here is what he did in case the above key inti. does not work for you;

1. unlock all the doors
2. get in, close the door.
3. put the key in and turn it to the (II) second position, this is the one just before turning the engine over.
3a. hold down the forward unlock (arrow) button, you know the hardest one to get to
3b. Now while holding down on that button, turn the key to off, pull it out of the ignition (are you still holding that button) Good.
4. Now with your 3rd hand (still holding that arrow button down, push the center BMW 3 times.
5. now let go of the forward arrow button and you should see your door locks go to the locked pos. then unlocked again.
6. Now with your other keys, just hold down the forward arrow button, pump the BMW button 3 times and then let go of the arrow button, walla you are worth $85. an hour. Note you just hold the other keys in your hand to inti. them, do not put in the ingition.
