Audi Workshop Service and Repair Manuals

Matching of vehicle keys   Note t  If new or additional ignition keys are required, they must be matched to the immobilizer. t  All ignition keys, including those already authorised, must always be re-matched. t  Re-matching of the remaining vehicle keys is particularly important if a key has been lost, as the lost vehicle key is then no longer authorised to start the vehicle. t  If it is not possible to match all keys, e.g. during a journey, customers must have this done at a later date at their local Audi dealership. t  The number of keys already matched is displayed after selecting “Adaption” function in “Channel 21” and in “measured value block 22”. t  The number of keys already matched is displayed after selecting the adaption function (channel 21). t  Once a key has been matched, it is interlocked and can no longer be matched to a different immobilizer system. Sequence of operations l  All ignition keys available. If there is no old ignition key available → Chapter „Procedure in the event of loss of key“. –  Insert the first key in the ignition lock and switch on the ignition. –  Establish the immobilizer identification number by starting immobilizer self-diagnosis → Chapter. –  Obtain the 7-digit PIN from the applicable regional sales centre/importer on the basis of the 14-position immobilizer identification number.   Note The PIN is only valid for one day, after which a new number has to be requested. The PIN is of no use to the customer or other dealerships.

–  Touch the Finished key. When this display appears, the immobilizer warning lamp -K115- in the dash panel insert lights and the immobilizer has been released.   Note t  Heed the instructions given on the display if a fault message appears.

t  3 attempts at entering a correct PIN are immediately possible. The next 3 attempts can only be made after waiting at least 10 minutes. To do so, the ignition must be left switched on and function “06 - End of output” must be selected from list -1- to exit from self-diagnosis. t  The waiting time after every 3 further incorrect entries is doubled in each case up to a maximum of 255 minutes. Once immobilizer has been released:

Display on -VAS 5051B-: –  From list -1- select function “10 - Adaption”.

Display on -VAS 5051B-: 1 -  Enter channel number –  On the keypad -2-, touch keys 21 for “Adaption channel 21” and confirm the entry by touching the Q key.

Display on -VAS 5051B-: 1 -  Channel 21 reading and testing 2 -  New number of keys: 4 -  Bar set to current adaption value, e.g. “2”. The display shows the number of ignition keys (in this case “2”) matched to the system.

Display on -VAS 5051B-: –  Enter the number of keys to be matched. Example: 4 keys including the one in the ignition lock   Note A maximum of 8 keys can be matched. –  Move the bar -5- to the right or touch the panel to the right of the bar until the bar is positioned under the number “4” (example).   Note It is also possible to touch the keypad key -Item 3-, then the key 4 and confirm the entry by touching the Q key. –  Touch the Save key -4-.

Display on -VAS 5051B-: 1 -  Channel 21 reading and testing 2 -  New number of keys: 4 -  Original value “2” new value “4” (example) –  Confirm the new adaption value by touching the Accept key -3-. Matching is then implemented. l  The matching time per key must not exceed 30 seconds. Otherwise the immobilizer warning lamp -K115- in the dash panel insert starts to flash and the release (PIN) procedure must be repeated in full.

Display on -VAS 5051B- following successful adaption: 1 -  Channel 21 value “4” stored The immobilizer warning lamp -K115- in the dash panel insert goes out; the key in the ignition lock has been matched. –  Terminate function “10 - Adaption” by touching ← key.

Display on -VAS 5051B-: –  From list -1-, select function “06 - End of output”. –  Switch off ignition. –  Insert the next key in the ignition lock and switch on the ignition. The immobilizer warning lamp -K115- lights when the ignition is switched on and goes out after approx. 1 second. This key has now also been matched. –  Repeat the procedure until all keys have been matched. With the last key, the immobilizer warning lamp -K115- goes out approx. 2 seconds after successful matching and a brief confirmation signal is given (warning lamp off for 0.5 seconds, warning lamp on for 0.5 seconds, warning lamp off). –  Interrogate the fault memory on completion of key matching → Chapter. If no fault has been stored, the “Key matching” function has been successfully completed. Ignition key matching is terminated automatically under the following conditions: t  On reaching the number of keys to be matched. t  If the ignition is switched on again with an already matched key and left switched on for more than 1 second (fault is stored). t  If the permitted matching time of 30 seconds per key after switching on the ignition is exceeded (fault is stored). t  If a fault is stored during the key matching procedure.
