2024 Subaru Ascent Smart Key Remote Fob Programming Instructions

Important Notice: The 2024 Subaru Ascent does not support onboard programming for smart key remote fobs. Programming requires a trained technician with access to manufacturer-level diagnostic tools.

Step-by-Step Programming Instructions:

• Step 1: Schedule an appointment with a certified automotive technician or authorized dealer equipped to program smart key systems using advanced diagnostic equipment.
• Step 2: Verify that the technician is experienced with proximity-based smart key technology and familiar with Subaru’s security protocols for newer models.
• Step 3: If your vehicle is drivable, transporting it to the service facility may be more cost-effective than requesting mobile assistance.
• Step 4: Bring all current remote fobs with you. In some systems, any remotes not present during programming may be deactivated and will need to be reprogrammed.
• Step 5: Be prepared to show proof of vehicle ownership, such as a valid title or registration document, especially if no working keys are currently available.
• Step 6: The technician will connect a professional diagnostic tool to the vehicle’s onboard computer to access the remote key programming menu.
• Step 7: The new smart key remote will be registered and securely paired with the vehicle’s electronic control unit, enabling keyless entry, remote start (if equipped), and push-button ignition.
• Step 8: After programming is completed, the technician will test all key fob functions to ensure proper operation, including locking, unlocking, panic alarm, and engine start. '
• Step 9: Check that previously programmed remotes are still functioning. If not, they may need to be reprogrammed during the same session.
• Step 10: It is recommended to have an extra smart key programmed at the same time for future convenience in case of loss or damage.
