Smart Key Remote Fob Programming Instructions for the 2017 Toyota Prius C

Important Notice: The 2017 Toyota Prius C does not support manual onboard programming for smart key remote fobs. A qualified automotive technician must complete the programming using specialized diagnostic equipment.

Programming Procedure:

• Step 1: Contact a certified technician who is experienced with Toyota smart key systems and has access to the appropriate diagnostic tools required for key programming.
• Step 2: If your vehicle is operational, consider bringing it to the technician's location to reduce service costs compared to a mobile visit.
• Step 3: Bring all current smart key remotes. Toyota systems often require all remotes to be present and reprogrammed together to maintain full functionality.
• Step 4: The technician will connect diagnostic equipment to the vehicle’s onboard port (OBD-II) to access the key registration menu.
• Step 5: Using secure Toyota-compatible software, the technician will program the new smart key fob, linking it to the vehicle’s control system to enable push-button start, remote locking/unlocking, and proximity entry.
• Step 6: Any old, lost, or inactive smart keys can be removed from the system during this process to improve security.
• Step 7: After programming, the technician will test all key functions—including engine start, remote entry, and locking/unlocking—to confirm proper operation.
• Step 8: The technician may inform you of how many remotes are currently registered and whether additional keys can be added in the future.
• Step 9: Store spare smart keys in a secure place and retain documentation of the programming service for your records.

Additional Tips:

• If no smart keys are available, be prepared to present proof of ownership (such as your registration or title) before programming can begin. Check remote battery life regularly and replace as needed to ensure consistent performance. Always keep a backup smart key stored safely for emergency use.
