2022 Subaru Ascent Smart Key Remote Fob Programming Instructions

Important Notice: The 2022 Subaru Ascent does not support onboard programming for smart key remote fobs. A qualified automotive technician must perform the programming using specialized diagnostic equipment.

Step-by-Step Programming Instructions:

• Step 1: Contact a certified automotive technician or authorized service provider equipped with the proper diagnostic tools required to program smart key systems.
• Step 2: Confirm that the technician is experienced with keyless entry and push-button start systems specific to your vehicle to ensure successful programming.
• Step 3: If the vehicle is drivable, consider taking it directly to the technician's location, which may help reduce service costs compared to requesting a mobile visit.
• Step 4: Bring any currently working remotes with you. Certain systems require all remotes to be present during programming to retain functionality.
• Step 5: Prepare proof of ownership—such as the vehicle’s title or registration—especially if all remotes have been lost or replaced.
• Step 6: The technician will connect advanced diagnostic equipment to the vehicle’s onboard system to initiate the key registration process.
• Step 7: The new smart key remote fob will be securely programmed to the vehicle’s electronic control module, allowing full keyless access and ignition capability.
• Step 8: After programming, the technician will test the remote to verify that all functions—lock, unlock, panic, and start—work properly.
• Step 9: Confirm that all previously programmed remotes remain operational. If any are not functioning, they may need to be reprogrammed during the same session.
• Step 10: Consider having a spare remote programmed at the same time to avoid inconvenience in the event of a future key loss.
