2017 Subaru Legacy Smart Key Remote Fob Programming Instructions

Important Notice: The 2017 Subaru Legacy does not support onboard programming for its smart key remote fob. Programming requires specialized diagnostic equipment and must be performed by a qualified automotive technician.

Programming Procedure:

• Step 1: Arrange service with a certified technician or authorized provider who is equipped to program smart key systems and access the vehicle’s onboard computer.
• Step 2: If your vehicle is drivable, consider taking it directly to the technician’s location. This may help reduce any additional service costs associated with on-site visits.
• Step 3: The technician will connect professional diagnostic tools to your vehicle to access the keyless entry system and register the new smart key fob.
• Step 4: Once programming is complete, the technician will verify that all remote functions—such as lock, unlock, and push-button start—are working properly.

Additional Notes:

• Proof of ownership may be required, especially if no functional keys are available. Depending on the system, all existing remotes may need to be present during the programming session. Ensure the technician has experience with Subaru smart key systems to avoid potential compatibility issues.
