2023 Toyota bZ4X – Smart Key Remote Fob Programming Guide

Important Notice: The 2023 Toyota bZ4X is equipped with an advanced smart key system that does not support onboard programming. All remote fob programming must be carried out using specialized diagnostic tools by a qualified automotive technician.

Programming Instructions:

• Step 1: Schedule service with an automotive technician who is trained in smart key systems and has access to the appropriate diagnostic programming equipment.
• Step 2: If the vehicle is drivable, transporting it to the technician’s location may help reduce service costs compared to requesting mobile assistance.
• Step 3: The technician will connect professional diagnostic tools to the vehicle’s onboard computer system to program and synchronize the new smart key fob.
• Step 4: All current and replacement remotes may need to be present during programming, as any remotes not detected could be removed from the system.
• Step 5: Once programming is complete, test the remote to ensure all functions—including locking, unlocking, and start features—are working properly.
