A BMW remote key contains 3 features...EWS, FZV, & DWA.
EWS data comes from BMW who already has the info and they send the new key already cut with the correct EWS transponder inside of it. The
FZV/DWA (central locking/anti-theft alarm sire system) features of the remote key must be programmed after receiving the key.
As posted multiple times a month...instructions on how to program the remote keys to
lock/unlock & arm/disarm (FZV/DWA) the vehicle are below. Instructions must be followed to the T...don't fudge, skip, overlook, or combine any of the steps...if so, programming will probably fail.
The new remote key (or regular key) will come from BMW already cut for the lock cylinders based on your car's VIN...as well as the EWS transponder (the immobilizing feature of the remote key & regular key) comes from the factory already with your car's ISN (individual serial number) assigned to the key. This was all taken care of when the car rolled off the assembly line. There were 10 keys (ISNs) programmed into your EWS control module...the original owner received 4 of them...which leaves the availability of 6 spares that BMW already has in preparation for replacement keys. (see info below)
Tips:
- lock & unlock the vehicle from the driver's door lock cylinder before initializing
- make sure ALL doors are closed before initializing
- make sure ALL doors are UNLOCKED before initializing
- insert 1st key into ignition and only turn it to POSITION 1 (this is KL R)...do NOT turn the key to position 2 or 3 or have the engine running.
- START the 2nd remote on STEP 3 where you start pressing the buttons...DO NOT insert the 2nd remote key into the ignition...if you do...the 1st remote will lose its programming
