2023 Toyota 4Runner Smart Key Remote Fob Programming Guide 

Important Notice: The 2023 Toyota 4Runner does not support onboard programming for smart key remote fobs. Programming requires the use of specialized diagnostic tools and must be performed by a qualified automotive technician.

Programming Procedure:

• Step 1: Contact a Certified Automotive Technician Locate a professional technician or service center with experience in keyless entry systems. Confirm they have the proper tools to program modern smart key fobs.
• Step 2: Determine Vehicle Mobility If your vehicle is drivable, consider taking it to the technician’s location. This can be more cost-effective than requesting mobile service.
• Step 3: Schedule a Programming Appointment Once you've selected a qualified technician, schedule a convenient time to have the programming completed. Mention whether any remotes are currently working.
• Step 4: Prepare Proof of Ownership If no functioning keys are available, you may be required to provide documentation such as the vehicle title or registration before programming can begin.
• Step 5: Technician Connects Diagnostic Equipment At the appointment, the technician will use specialized diagnostic tools to interface with your vehicle’s onboard computer and program the new remote fob.
• Step 6: Confirm Remote Functionality After programming, test all key fob features—lock, unlock, panic, and start functions (if equipped)—to ensure proper operation.

Additional Considerations:

• Have All Remotes Present: Some systems require all remotes to be programmed at the same time to retain functionality. Use an Experienced Technician: A knowledgeable professional ensures accurate setup and compatibility with your vehicle’s smart key system.
