- Adaptation: After successfully logging in, click on “Adaptation – 10.”
2.4. Programming the New Key
- Channel Selection: Enter channel “01” in the channel selection field. This channel is used for key matching.
- Read Value: Click “Read” to display the number of currently stored keys in “Stored Value.”
- Enter New Value: In the “New Value” field, enter the total number of keys you want to program, up to a maximum of 4. This includes existing keys and the new key.
- Test: Click “Test” to verify that the number in “Test Value” is correct.
- Save: Click “Save” to save the new value.
The Adaptation Channel screen in VCDS allows you to modify stored values.
2.5. Key Synchronization
- Synchronization: Immediately after saving, remove the existing key from the ignition and insert the new key.
- Press Unlock: Press and hold the UNLOCK button on the new key for at least one second.
- Confirmation: The car may give you an acknowledgement, such as flashing lights or a horn beep, to indicate that the key has been learned.
- Repeat: If you are programming multiple keys, repeat the process for each key within 15 seconds.
2.6. Alternative Procedure (If Channel 01 is Unavailable)
If channel 01 is not available, follow this alternative procedure:
- Insert Working Key: Insert a working key into the ignition and turn it to the ON position (do not start the car).
- Select Control Module: In VCDS, select “46 – Cent. Conv.” or “35 – Cent. Locking,” whichever is applicable to the car.
- Meas. Blocks: Click on “Meas. Blocks – 08.”
- Enter Group: Enter group “003” (may be group “007” in some vehicles).
- Go!: Click “Go!”
- Lock with New Key: Lock the car from the outside using the new, unmatched key in the driver-side door lock.
- Press Unlock: Press the UNLOCK button on the new key within 5 seconds, often enough to reach the next memory position. For example, if the value in field 2 was 0001, press the new key’s unlock button twice to put the new key in memory position 2.
- Wait and Unlock: Wait 5 seconds and press the unlock button on the new key to unlock the door.
- Turn Off Ignition: Turn the ignition key to OFF and remove the old key.
- Test New Key: Press LOCK and UNLOCK with the new key.
- Verify: Insert the new key in the ignition and turn to the ON position (do not start the car). Check Meas. Blocks group “003” to verify that the new key is matched.
2.7. Clearing Existing Matched Remotes (If Necessary)
In some cases, it may be necessary to clear out existing matched remotes:
- Select Control Module: In VCDS, select “46 – Cent. Conv.” or “35 – Cent. Locking.”
