Ignition Key In Signal: Service and Repair
Adaptation: Matching Ignition Keys To Radio Frequency Remote Control
NOTE:
- If new or additional ignition keys are required they must be matched to the immobilizer and comfort system control electronics.
- The matching procedure must always be carried out for all the ignition keys, including the existing ones.
- The number of keys already matched will be displayed when the adaptation (matching) function is selected.
- With the introduction of this generation of comfort system it is possible to program additional functions. The functions and the programming are described.
- The matching can be interrupted with the "C" key of the VAG 1551
WARNING!
The VAG 1551 dealership number (Dealership code) will be stored in immobilizer control module when matching ignition keys.

Select function XX
- A button must be pressed once on each of the radio frequency keys to be "learned" (in example above, 3 keys).
- Switch off ignition and remove ignition key.
- Perform functional check (e.g. 3) of radio frequency keys.
NOTE:
- All 3 keys (See example) can be "learned" in one matching sequence.
- 15 seconds must not be exceeded when matching all ignition keys (pressing a button).
- A successful adaptation can be determined via Read Measured Value Block, function 08, display group number 013. When operation the radio frequency unit both of first measurement values must have the status OK. Simultaneously the last measurement value will show the positional number of the key (i.e. first, second, third, fourth key).
- If the remote control key is operated several times the third display "no measured value" changes to "OK".
The matching of ignition keys is automatically terminated when:
- Number of keys to be matched is reached.
- A button of one of the keys to be "learned" is pressed frequently.
- Permissible matching period of 15 seconds is exceeded (DTC is stored).
- Select function 02 "Check DTC Memory". If there is no DTC stored, the matching of the keys has been successfully completed.
- Press keys -0- and -6- to end the output.
