this is the procedure for "coding" your key to the remote control, not to the car.Hi All
I'm not sure if this is common knowledge, but was a surprise to me. I ordered a new key for my M5 (since I only got one with the car from the previous owner). The key arrived at the dealer and obviously needed to be programmed to the car. I was expecting a connection to the computer and at least half an hours worth of labour cost. But no...
The service rep hops into the car and preceded to do the following:
1) Get in and close drivers door
2) Open and close drivers door again
3) Insert old key into ignition and turn to position 1
4) Turn off and remove key
5) On the old key hold down the lock button (one in middle of key) and press the unlock button three times. You should hear the car lock.
6) Now take the new key and do the same. I.e hold down the lock button and press the unlock button three times. You should hear the car unlock - if you do it has worked.
7) Wait 30 seconds. Insert new key and see if car starts.
It did take two goes to get it to work on my car. It has also disabled the autolock feature for some reason, but this may be related to the fact that you can have different setups in the car for the different keys (the aircon temps were also different when I started the car with the new key)
Anyone else know about this? I think I got the sequence right - it happened rather fast and seems like he had done it a few times before.
This was also a brand new key from the factory so I don't know if it will work for an "eBay" key.
In addition to this procedure there is also a chip in your key that permits it to work only in your vehicle. That coding was done before the dealership received your key. In other words, don't expect to buy a key off EBay and get it to work with your car by following this procedure.
