You
MUST program
BOTH keys during the same session. Any remote key not programmed during the same session, will no longer be able to lock/unlock & arm/disarm the car's alarm. It will still be able to START the car...but the
FZV/DWA (keyless entry/anti-theft alarm system) will be disabled for the key not present. This is one deterrent for "remote" access when a key is lost or stolen...if you reprogram your remaining remote key(s)...the lost/stolen key will no longer have "remote" capability...and if you can also "bar" the lost/stolen key from starting the car if you go to your BMW dealer (or have the aftermarket software/hardware like INPA etc.)
The remote keys contain 3 features:
- EWS (immobilizing "drive-a-way protection)
- FZV (remote/keyless entry)
- DWA (anti-theft alarm siren system
If you need to reinitialize your keys...you will only be reprogramming FZV & DWA. EWS can only be programmed using dedicated BMW DIS equipment (or the aftermarket stuff) You
MUST follow the reinitializing instructions to the
T. Do not fudge, skip, ignore, combine any of the steps below. The
2nd key should NOT be inserted into the ignition...but start it on
STEP 3 where you start pushing/holding the buttons:
TIPS:
- KL R = ignition position 1
- You can remove the 1st key from the ignition in STEP 3 after you've turned the ignition back OFF
- Start the 2nd, 3rd, 4th remote key on STEP 3...DO NOT insert them into the ignition...to do so will cause the 1st key to LOSE its programming.
