Programming Guide for 2015 Audi S6 Keyless Entry Smart Key Remote Fob

Important Notice: The 2015 Audi S6 does not support onboard programming for smart key remote fobs. A qualified automotive professional must perform the programming using Audi-specific diagnostic tools.

Programming Procedure:

• Step 1: Contact a certified technician or authorized Audi service provider with access to factory-grade diagnostic equipment required for key fob programming.
• Step 2: If the vehicle is drivable, it is typically more cost-effective to bring it directly to the service provider rather than requesting mobile service.
• Step 3: Ensure the technician is experienced with Audi’s security systems and smart key integration to avoid issues during programming.
• Step 4: Bring all existing and replacement smart key fobs. Any remotes not present during the session may be removed from the system and will need reprogramming later.
• Step 5: The technician will connect diagnostic tools to the vehicle’s OBD-II port and access the key management system through Audi’s control modules.
• Step 6: Using the diagnostic interface, the technician will initiate the smart key programming process to register each fob with the vehicle’s locking, ignition, and security systems.
• Step 7: Each programmed key fob will be tested to ensure full functionality, including lock/unlock, trunk access, and push-to-start operation.
• Step 8: If any fob fails during testing, the technician will troubleshoot and reprogram as necessary to ensure a successful pairing.
• Step 9: Once all smart keys are programmed and confirmed to be working, the system will exit programming mode, and normal operation will resume.
