Important Notice: The 2016 Toyota Tundra does not support onboard programming for smart key fobs or remote head keys. Programming must be performed using advanced diagnostic equipment by a trained automotive technician. This process cannot be completed manually or at home.

Programming Requirements

  • Step 1: Determine the Key Type Your Tundra may use one of the following key systems: Remote Head Key – A traditional key with integrated lock/unlock buttons. Smart Key Fob – A proximity-based remote used with push-button start ignition. Both configurations require secure electronic registration via the vehicle's onboard control modules.
  • Step 2: Programming Must Be Performed by a Professional Technician A qualified technician will: Connect a manufacturer-approved scan tool to the vehicle’s OBD-II diagnostic port. Access the Body Control Module (BCM) and immobilizer ECU to program the new key fob into the vehicle's memory. Verify that the fob communicates correctly with both the security and ignition systems.
  • Step 3: Prepare Before the Programming Appointment To ensure a successful session: Bring all remotes that you wish to continue using. During programming, previously stored remotes may be cleared and must be reprogrammed. Provide proof of vehicle ownership, such as your title or registration, especially if no functioning remote is currently available. Install a new battery in the remote to prevent signal loss during the pairing process.

Additional Information Remote Capacity:

If no functional key or remote is available, the vehicle may require additional security procedures, including immobilizer reset. Test After Programming: Always verify full functionality of each remote—lock, unlock, panic alarm, and engine start (if equipped)—once programming is complete. Applies to Factory Systems: These instructions are specific to Toyota’s factory-installed keyless entry system. If your vehicle has an aftermarket system, refer to the appropriate documentation.
