2019 Toyota Avalon – Smart Key Remote Fob Programming Guide

Important Notice: The 2019 Toyota Avalon features a smart key system that does not support onboard programming. All remote fob programming must be performed using professional diagnostic tools by a qualified automotive technician.

Programming Instructions:

• Step 1: Arrange service with a certified technician who is experienced in smart key systems and has access to the appropriate diagnostic programming equipment.
• Step 2: If the vehicle is operable, transporting it to the technician’s location may help lower service costs compared to mobile visits.
• Step 3: The technician will connect specialized diagnostic equipment to the vehicle’s onboard system to program and sync the new smart key fob.
• Step 4: All existing and new remotes may need to be present during the session, as some systems may remove any remotes not detected.
• Step 5: Once programming is complete, test all remote features—such as lock, unlock, and push-button start—to ensure proper functionality.
