Programming Guide for 2022 Audi S4 Keyless Entry Smart Key Remote Fob

Important Notice: The 2022 Audi S4 does not support onboard programming for smart key remote fobs. Programming must be completed by a qualified professional using specialized diagnostic equipment designed for Audi systems.

Programming Procedure:

  • Step 1: Contact a certified automotive technician or authorized service provider equipped to program smart key systems for Audi vehicles.
  • Step 2: If your vehicle is operational, consider driving it to the service location to reduce the cost of programming. Mobile service may be more expensive.
  • Step 3: Ensure the technician has specific experience with Audi smart key technology to avoid compatibility or security system errors.
  • Step 4: Bring all existing and new remote fobs. Any remotes not present during the session may be erased from the vehicle’s memory.
  • Step 5: The technician will connect professional-grade diagnostic tools to the vehicle’s onboard computer through the OBD-II port.
  • Step 6: Using the diagnostic system, the technician will enter programming mode and pair the new smart key fob to the vehicle’s immobilizer and central locking system.
  • Step 7: All functions of the newly programmed remote—such as lock/unlock, trunk release, and engine start—will be tested for proper operation.
  • Step 8: If any issues arise, the technician will troubleshoot using the diagnostic interface to ensure successful communication and pairing.
  • Step 9: After programming is complete, the system will be exited from programming mode, and the technician will verify that all programmed keys are functioning as intended.

Additional Considerations:

  • Ownership Documentation: Be prepared to show proof of ownership (such as registration or title) if no working keys are available.
  • Remote Limit: The Audi S4 typically allows a limited number of stored remotes. Program all remotes during the same session.
  • Key Compatibility: Only use remotes specifically made for the 2022 Audi S4 to ensure full compatibility and functionality.
