You may find that your remote has stopped responding to your car. In the event that this happens, or if you need to pair the remote to you car for any reason, the following is the procedure. It took me about 10 tries to get this to work, so you may have to keep trying. For the two remotes I paired using this procedure, step 4 did not cause the doors to lock/unlock. I had to hit buttons in order to tell that the remote had been initialized. I found two procedures, so you may have luck with one and not the other. Try both if necessary, and try them several times if necessary.
The Pairing procedures as stated in documentation from Mini with some input be me are as follows:
Procedure #1.
1.) Unlock vehicle via central locking and close driver's and passenger's doors. (Central locking is the console switch under the radio)
2.) Switch the ignition switch to KL-R (first turn), switch back off within 5 seconds and remove the key
3.) Within 30 seconds, press and hold the unlock button and at the same time, press and release the lock button (3) times. (Must be completed within 10 seconds)
4.) Release both buttons. The doors will lock/unlock to signal a successful initialization.
5.) If additional keys need to be initialized, repeat steps 3-4 within 30 seconds
6.) Switching the ignition to KL-R completes the initialization
Procedure #2.
Key Initialization
If the BC1 rolling key code becomes out of step with the remote key, synchronization is required. The
synchronization procedure can be carried out in two ways:
1. Press either the remote key lock or unlock button four times in succession.
2. With the car unlocked, switch on the ignition briefly and then off and remove the key, now within 10-
seconds press the lock and unlock buttons in succession.
It is not necessary to synchronize all the keys together. As the key codes are stored in the BC1, the
synchronization procedure is simply aligning the rolling code in the BC1 to the individual key and will not
affect any additional keys
