Smart Key Remote Fob Programming Instructions for the 2015 Toyota Prius C

Important Notice: The 2015 Toyota Prius C does not support onboard programming for smart key remote fobs. Programming must be performed by a qualified technician using specialized diagnostic equipment.

Programming Procedure:

• Step 1: Contact a certified technician experienced with Toyota smart key systems who has access to factory-compatible diagnostic tools for key registration.
• Step 2: If the vehicle is operable, it may be more cost-effective to drive it to the technician’s location rather than requesting mobile service.
• Step 3: Be sure to bring all working smart key remotes. The Prius C system may require that all remotes be present during the session to remain functional after programming.
• Step 4: The technician will connect diagnostic equipment to the vehicle's OBD-II port and access the key programming interface in the vehicle's control module.
• Step 5: Using secure Toyota-compatible software, the technician will register the new smart key fob, enabling all standard features such as push-button start, remote locking/unlocking, and proximity entry.
• Step 6: Any lost or unused remotes can be deleted from the system to enhance vehicle security.
• Step 7: After programming is complete, all smart key functions will be tested to ensure proper operation, including engine start and keyless entry.
• Step 8: The technician may confirm how many keys are currently registered and whether additional smart key fobs can be added in the future.
• Step 9: Store any spare remotes securely, and retain documentation of the programming session for future reference.

Additional Tips:

• If all smart keys are lost, be prepared to provide proof of ownership, such as a vehicle registration or title. Replace the key fob battery when needed to maintain reliable operation. Keep a backup smart key stored in a safe location for emergency use.
