2019 Toyota 4Runner Smart Key Remote Fob Programming Guide

Important Notice: The 2019 Toyota 4Runner does not support onboard programming for smart key or remote head key fobs. Programming must be carried out by a qualified technician using specialized diagnostic tools.

Programming Procedure:

• Step 1: Contact a Certified Automotive Technician Locate a service provider experienced in keyless entry systems. Make sure they have the appropriate tools to program both smart key and remote head key fobs.
• Step 2: Determine Your Ignition Type Identify whether your vehicle uses a push-button start or a standard turn-key ignition. This information is essential for selecting the correct programming method.
• Step 3: Schedule a Programming Appointment After confirming the ignition type, set up a service appointment with a technician familiar with your vehicle’s key system.
• Step 4: Provide Proof of Ownership If no functioning remote is available, you may be asked to present documentation such as the vehicle registration or title before programming begins.
• Step 5: Technician Connects Programming Equipment At your appointment, the technician will use professional diagnostic equipment to access the vehicle’s onboard system and program the new remote fob.
• Step 6: Verify Remote Functionality Once programming is complete, test all remote features—lock, unlock, remote start (if equipped), and panic alarm—to ensure everything is functioning properly.

Additional Considerations:

• Bring All Remotes to the Appointment: Some systems require all remotes to be present during programming, as previously paired fobs may be erased. Choose a Technician Experienced with Smart Keys: Proper programming depends on working with professionals who are trained in advanced key systems.
