Important Notice: The 2021 Toyota Avalon is equipped with a smart key system that does not support onboard programming. Programming a new smart key remote requires specialized diagnostic equipment and must be performed by a qualified automotive technician.

Programming Instructions:

• Step 1: Contact a professional technician who is certified to program smart key systems and equipped with the proper diagnostic tools.
• Step 2: If the vehicle is operational, consider driving it to the technician’s facility to help reduce any additional costs associated with mobile service.
• Step 3: The technician will connect diagnostic equipment to the vehicle’s onboard system to program and pair the new smart key remote.
• Step 4: Be sure to bring all existing remotes, as the system may clear any remotes not present during the programming process.
• Step 5: Once programming is complete, test all functions of the smart key, including lock, unlock, and push-button start, to confirm successful operation.
