2016 Toyota 4Runner Smart Key Remote Fob Programming Guide

Important Notice: The 2016 Toyota 4Runner does not support onboard programming for smart key or remote head key fobs. Programming must be performed by a qualified technician using specialized diagnostic tools.

Programming Procedure:

• Step 1: Contact a Certified Automotive Technician Locate an experienced technician or service center that specializes in electronic key programming. Ensure they are equipped with the correct tools for both smart keys and remote head keys.
• Step 2: Identify Your Ignition Type Determine whether your vehicle uses a push-button start or a traditional turn-key ignition. This will guide the technician in selecting the appropriate programming process.
• Step 3: Book a Programming Appointment Once the ignition system type is confirmed, schedule a programming session with a qualified professional who can handle your specific key type.
• Step 4: Prepare Proof of Ownership If no working keys are available, be ready to provide documentation such as the vehicle title or registration to verify ownership before programming can begin.
• Step 5: Technician Performs the Programming During your appointment, the technician will connect diagnostic equipment to the vehicle’s onboard system and program the new remote fob or smart key securely.
• Step 6: Test All Remote Functions After programming, check all remote features—including lock, unlock, panic button, and engine start—to ensure full and proper functionality.

Additional Considerations:

• Have All Remotes Available: Some systems may erase previous remotes during programming. Bring all fobs to be reprogrammed at the same time. Use a Technician Experienced with Smart Key Systems: Working with a knowledgeable professional helps prevent errors and ensures successful key registration.
