 Important! Before ordering keys,
 simultaneous locks, ECUs
 (immobiliser/CAS) etc., it is necessary
 to ensure the procurement authorisation
 of the customer and the vehicle owner
 by producing the original vehicle
 documents and official photo
 identification! A power of attorney
 from the vehicle owner is also required
 for authorised third parties. Copies of
 the specified credentials (proof of
 authorisation) must be kept in the
 vehicle records. Please inform BMW
 Service immediately if a vehicle key is
 lost so it can be deactivated in order
 to avoid taking the risk of losing the
 insurance cover due to gross negligence
 in the event of a theft.
