Programming Guide for 2025 Smart Keyless Entry Remote Fob

Important Notice: The 2025 model does not support onboard programming for smart key remote fobs. Adding or replacing a remote requires the use of specialized diagnostic equipment and must be completed by a qualified automotive professional.

Smart Key Programming Instructions (Professional Assistance Required):

  • Step 1: Confirm that you need to program a new or replacement smart key remote fob. This includes scenarios such as lost keys, damaged fobs, or adding additional remotes.
  • Step 2: Ensure you have all current remotes in your possession. During the programming process, existing remotes may be erased and must be reprogrammed along with the new one.
  • Step 3: Prepare documents that confirm ownership of the vehicle. This may include your vehicle title, registration, or driver’s license with matching information. These are often required before service can be provided.
  • Step 4: Locate a certified automotive technician or dealer service department that has the proper tools to program a smart key remote for your vehicle. Only professionals with advanced diagnostic equipment can perform the programming.
  • Step 5: If your vehicle is still drivable, consider transporting it directly to the service location. This may help reduce service fees compared to scheduling mobile assistance.
  • Step 6: Once at the service location, the technician will connect professional-grade diagnostic tools to the vehicle’s onboard system, usually via the OBD-II port.
  • Step 7: The technician will initiate the smart key programming process using specialized software that communicates directly with the vehicle’s security and key recognition modules.
  • Step 8: The new remote fob will be paired to the vehicle's electronic system. Any existing remotes that are present may be reprogrammed at this time to retain functionality.
  • Step 9: After programming is complete, each remote will be tested for proper operation, including remote locking, unlocking, and engine start functions.
  • Step 10: Before leaving, confirm that all remotes function as expected. Test all buttons and remote start features to ensure successful programming.

Additional Considerations:

Maximum Number of Remotes: Up to eight remotes can be programmed for this vehicle.

Security Verification: If all remotes are lost, proof of ownership is typically mandatory before programming can begin.

Technical Limitations: Attempting to program a smart key remote without professional tools or training may result in system errors or failure.
