Matching of radio-operated remote control keys

The vehicle is supplied with two radio-operated remote control keys.

If new or additional ignition keys are required they must be adapted to the immobiliser control electronics.

=> Electrical System; Repair group 01; Immobiliser Self-diagnosis - Immobiliser III

In addition, the radio-operated remote control keys must also be matched/adapted to the convenience system central control unit -J393.

Methods of matching radio-operated remote control keys:

  • ◆ To match radio-operated remote control keys without a second key, the procedure is described further in adaption under channel 21. Matching of radio-operated remote control keys via adaption =>Page 01-72.
  • ◆ To match radio-operated remote control keys by using a second key, follow the following steps.

Matching procedure for new radio-operated remote control keys

  • ‒ Unlock the vehicle from the outside via the driver's door lock.
  • ‒ Switch on the ignition (using additional key).
  • ‒ Check how many keys have already been matched in measured value bock 007 => Read measured value block, Page 01-53.
 
→ Indicated on display:
Read measured value block    7    ⇒
    0    0000    1100

Display zone 3 shows how many radio-operated remote control keys have been matched and in which memory positions (2x in positions 1 and 2 in example shown).

  • ‒ Lock vehicle from outside with the key to be adapted by way of the driver's door lock.
  • ‒ Within 5 seconds press "unlock" key of radio-operated remote control key until next memory position is reached (3x in example).
  • Each time the button is pressed, the hazard lights flash to confirm.
  • ‒ Wait 5 seconds.
  • ‒ Then press "unlock" button on the radio-operated remote control key again. This unlocks the vehicle.
    =>Key has been successfully matched.
  • ‒ Switch off ignition and remove ignition key.
  • ‒ Check function of new radio-operated remote control key.
  • ‒ Check display zone 3 in measured value block 007. It must now contain an additional "1" (in example: 1110).
 
→ Indicated on display:
Read measured value block    7    ⇒
    0    0000    1110

Notes:

  • ◆ Make sure new keys are always matched to vacant memory positions. If use is made of occupied memory positions (can be seen from "1") the radio-operated remote control key already matched for this memory position will no longer function.
  • ◆ If remote control locking or unlocking is actuated consecutively five times during the matching stage (within the 5 seconds), all the keys are "unmatched". In this case, the key matching procedure must be repeated.
  • ◆ A maximum of four keys can be matched.
  • ◆ The matching process must be completed within 30 seconds. If 30 seconds are exceeded the process must be repeated.
