2021 Honda Odyssey – Smart Key Remote Fob Programming Guide

Important Notice: The 2021 Honda Odyssey is equipped with an advanced smart key system that cannot be programmed manually or through onboard procedures. Remote fob programming must be completed using specialized diagnostic equipment by a qualified automotive technician.

Programming Instructions:

• Step 1: Schedule service with a technician who is certified and equipped with the proper diagnostic tools for smart key programming.
• Step 2: If the vehicle is drivable, transporting it to the technician’s location may help reduce costs associated with mobile service.
• Step 3: The technician will connect professional diagnostic equipment to the vehicle’s system to pair and activate the new smart key remote fob.
• Step 4: All remotes, both new and previously programmed, may need to be present during the session to ensure continued functionality.
• Step 5: Once programming is complete, verify that all functions—such as lock, unlock, and push-button start—work as intended.
