Replacement Remote Control Key Is Inoperative (SI B66 06 21)

REPLACEMENT REMOTE CONTROL KEY IS INOPERATIVE

SERVICE CAMPAIGN BULLETIN

SITUATION

Replacement remote-control key does not work or initialize.

CAUSE

Several reasons can cause this concern:

• Incorrect Vehicle Identification Number (VIN) entered when ordering the new remote-control key
• Initialization procedure incorrectly performed or not performed at all
• Remote-control key battery discharged or faulty
• Replacement remote-control key is defective
• Defective locking and security control module (e.g., CAS, FEM or BDC)

PROCEDURE

Follow this step-by-step procedure when initialization has failed on the replacement key.

1. Verify the correct VIN is on the body (door jamb). Electronically verify the VIN by using a working key on a KeyReader (Avoid relying on the vehicle registration card provided by the customer). 
   IMPORTANT: The new key can only be read by the key reader after initialization.
2. Make sure a working remote is not inside the vehicle; it may block the new one.
3. Disconnect all USB plug-in accessories, Bluetooth devices and remove any media in a disk drive.
4. Ensure the batteries on the new remote-control key are in good condition; or swap a known good remote-control battery.
   • Older vehicle keys without a replaceable battery should be recharged for 5 minutes. Charging should take place using ISPA Next or by inserting the remote key into the vehicle's ignition lock.
5. Enable the key by performing the manual procedure or service function below:
   • Enabling procedure for ZKE and EWS for older vehicles with this key style: 

   Initialization procedure: 

   1. Open the central locking system (ZV) using the ignition key.
   2. Get into the vehicle and close all doors.
   3. With an ignition key, turn the ignition lock briefly to ignition lock position 1, switching it on and back off again.
      • It must remain switched on for less than 5 seconds, otherwise the system will not be ready to initialise
   4. On the master key, press button 2 and hold it down.
   5. Press button 1 three times (within 10 seconds) while holding button 2 pressed down.
   6. Release button 2.
   7. The ZV signals that a master key has been initialized successfully with "locking" and immediate "unlocking" messages.
      • Vehicles equipped with CAS module (e.g., E90, E65, E66) key enabling service function is available in ISTA: 
        • Vehicle Management
        • Service functions
        • Body
        • Locking and security functions
        • Block and enable remote key
        • Disable missing keys from the vehicle and enable only the available keys.
   NOTE: Comfort Access only allows 2 keys to be enabled at the same time.
   NOTE: On vehicles equipped with a CAS module, at least one good working key needs to be available to teach in a new replacement Key. Otherwise, CAS with key set part number may be required.
   • Enabling procedure for F and G series vehicles (FEM/BDC): 
     1. Remove all existing keys from the passenger compartment except for the new key.
     2. Press the START/STOP button. The Check Control message "No remote key found" appears, and then the request to hold the key at the ring aerial.
     3. Hold the new remote against the steering column between the ring aerial marks. Press the START/STOP button again. If necessary, press the START/STOP button several times until the ignition can be switched on.
        NOTE: On early production vehicles, hold the key slightly off to the right of the marks. On difficult cases, performing a battery reset and an updating of the new key data by pressing and holding central lock button with the key on steering column will allow to initialize the new remote key.
     4. Perform a functional check, i.e., lock/unlock the central locking system and engine start.

   If the manual procedure is not successful, perform service function available on ISTA: 

   • Service functions
   • Body
   • Locking and security functions
   • Block and enable remote key.

   Confirm all keys are enabled (none are blocked). 

6. Repeat steps  4 to  5 a few times if necessary.
7. Does the remote-control lock/unlock the central locking system and start the vehicle?

   Yes:  No additional work necessary.

   No:  Verify that the VIN number on the DME label matches the VIN number on the vehicle chassis and inquire with the customer if any modules (CAS, EWS, BDC, DME) have been exchanged from another vehicle.

8. Does the DME VIN match the chassis VIN, and the new remote key label?

   No:  Advise the customer that the vehicle will need all the original VIN specific components, which may not be covered under warranty.

   Yes:  Submit an Integrated Dealer Support (IDS) coded parts ticket through t e Dealer Portal (SGATE).

   Navigate to: 

   • Coded Parts RDC
   • Coded Parts RDC
   • CREATE A TICKET
   NOTE: Include the full 17-digit VIN.
9. The Coded parts team will provide guidance on how to proceed further. Please do not order a second key unless instructed to do so.
