2003 Mini Cooper Base, Automatic CVTFACTORY OEM SERVICE PROCEDURE

Key Initialization: Notes

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:

  • Press either the remote key lock or unlock button four times in succession.
  • 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.
