2019 Subaru Legacy Smart Key Remote Fob Programming Instructions

Important Notice: The 2019 Subaru Legacy does not allow onboard programming for its smart key remote fob. This process must be performed by a qualified automotive technician using advanced diagnostic tools.

Programming Procedure:

• Step 1: Contact a certified technician or authorized automotive service provider who has the proper equipment to program smart key systems.
• Step 2: If your vehicle is drivable, it may be more cost-effective to take it to the technician’s facility rather than requesting on-site service.
• Step 3: The technician will connect a diagnostic interface to your vehicle’s onboard system to begin the key fob registration process.
• Step 4: Once the smart key has been successfully programmed, the technician will test all remote functions—including locking, unlocking, and push-button start—to confirm proper functionality.

Additional Notes:

• If no functioning remotes are available, you may be required to present proof of ownership (such as a vehicle title or registration). Some systems require all remotes to be present during programming to prevent older fobs from being erased. Ensure your technician is experienced with Subaru smart key systems to avoid programming errors.
