Syntes jeg har prøvet alt, er der nogen der ved med sikkerhed hvordan man koder nye fjernbetjeninger på en Audi A2.

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 block 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.


Self-diagnosis for convenience system
Synchronising/re-matching of existing radio-operated remote control keys
Radio-operated remote control keys must be synchronised if the vehicle can no longer be unlocked or locked via remote control and the key data is already known to the vehicle (can be recognised by fault memory entry "00955 to 00958 - keys 1 to 4").

Method for synchronising radio-operated remote control keys for vehicles with data level up to "09xx" (see Note)

‒ Press a button on the radio-operated remote control key.
If the vehicle is neither locked nor unlocked:

‒ Lock and unlock the vehicle within 30 seconds the via driver's door lock.
‒ Then check the function of the re-matched radio-operated remote control key.
If the vehicle still cannot be locked or unlocked, the key must be re-matched/adapted.

New methods for synchronising radio-operated remote control keys for vehicles with data levels as of "10xx" (see Note; introduced from model year '03)

‒ If the vehicle is locked, unlock it with the key via the lock in the driver's door.
‒ Press the unlock button on the radio-operated remote control key (fault is stored).
‒ Insert the key in the ignition lock and switch on the ignition (valid immobiliser message).
‒ Switch off the ignition again and remove the ignition key.
‒ Press the unlocking or locking button on the radio-operated remote control key (command is executed).
If the vehicle still cannot be locked or unlocked, the key must be re-matched/adapted.

Notes:

◆ The data level of the convenience system central control unit can be established via the function "01 - Interrogate control unit version".
◆ Following replacement or disconnection of the battery during repair work requiring this, all the radio-operated remote control keys for the vehicle must be synchronised.
◆ When changing the battery of a radio-operated remote control key, only that particular key must be synchronised.
◆ If the synchronisation procedure is unsuccessful, matching of the radio-operated remote control key(s) to the convenience system central control unit must be performed.
