Vehicle Key, Checking Function And Entering Number Of Assigned Keys

WARNING: This page is about a different car, the 2025 Audi S3, 2025 Audi RS 3, and 2025 Audi A3 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

Procedure:

-- Separate the set of keys so that the function of each key can be checked individually.

-- Start the engine using each key separately.

-- Enter the number of vehicle keys adapted and given in the Maintenance Table.

-- If a vehicle key is not adapted, readapt all existing vehicle keys to the vehicle using the Guided Functions on the Vehicle Diagnostic Tester via the GeKo online connection.

-- If there is suspicion of misuse (for example, a key is missing), pay attention to the current Audi AG information in ServiceNet under "Technical Service → Anti-theft protection".

NOTE:

Only store the key to be checked in the vehicle interior. Move the other keys outside of the operating range.

The engine switches off again after a few seconds if the key is not adapted. Depending on the vehicle equipment, the anti-theft immobilizer system indicator lamp or the display "SAFE" also appears in the instrument cluster.
