BMW use specially encrypted keys that are produced specifically to the VIN. Because of this, making replacement keys for BMW is technically not possible as there is no on-board programming procedure for new keys. However, for most models, we have the ability to calculate the key data directly from the EWS, CAS, FEM or BDC unit (immobiliser ECU) and produce keys ready to start the car. This allows us to program blank keys from our stock which makes the whole process significantly faster. We can currently support all E Series and most F Series vehicles. We are currently unable to assist with G series vehicles at present.
