Smart Key Remote Fob Programming Guide – 2019 Toyota Sienna

Important Notice: This vehicle does not support onboard or self-programming. All key types—smart keys, remote fobs, and integrated keys—must be programmed using professional diagnostic equipment by a trained technician. Follow the steps below based on your key configuration. Smart Key System (Push-Button Start Ignition) Vehicles with push-button start systems use smart keys that operate wirelessly. These must be electronically registered to the vehicle’s systems.

Programming Steps:

  • Step 1: Schedule programming with a technician who has access to factory-grade diagnostic tools.
  • Step 2: Confirm that the new smart key is compatible with your vehicle’s push-button ignition system.
  • Step 3: Bring all current smart keys to the appointment, as any missing keys may be deactivated.
  • Step 4: The technician will connect to the vehicle’s onboard system to initiate key registration.
  • Step 5: The new smart key will be programmed to control engine start, entry functions, and security systems.
  • Step 6: After programming, test the smart key to ensure lock, unlock, trunk release, and engine start features function correctly. Standard Remote Key Fob (Physical Key + Separate Remote)

This configuration uses a traditional ignition key and a separate remote fob for door lock and unlock functions.

Programming Steps:

  • Step 1: Arrange for programming with a technician who can interface with the vehicle’s keyless entry system.
  • Step 2: Ensure the remote is the correct match for your vehicle’s year and trim.
  • Step 3: Bring all remotes to the session—any not present may be removed from the system.
  • Step 4: The technician will use diagnostic tools to access the programming mode and pair the new remote.
  • Step 5: Once completed, verify that lock, unlock, and panic functions operate as expected.
  • Step 6: Repeat the process for any additional remotes you wish to program. Remote Head Key or Chip Key (Integrated Ignition Key + Remote Buttons)

This type of key includes both the transponder chip for ignition and buttons for remote entry, all in one unit.

Programming Steps:

  • Step 1: Verify the replacement key matches your vehicle’s transponder and remote specifications.
  • Step 2: Schedule programming with a technician experienced in key immobilizer and entry system setup.
  • Step 3: The ignition chip will be registered to the vehicle’s immobilizer to authorize engine starting.
  • Step 4: The remote functions will be paired with the door locking and security systems.
  • Step 5: Provide proof of ownership (such as title or registration) if required for security purposes.
  • Step 6: After programming, test all functions—start, lock, unlock, and trunk—to confirm success.

Additional Tips and Considerations:

  • Step 1: Onboard programming is not supported for this model—technician-only service is required.
  • Step 2: Always bring all working keys and remotes to the programming session.
  • Step 3: Use only OEM-compatible or vehicle-specific remotes to avoid compatibility issues.
  • Step 4: Ensure batteries in all remotes are fresh before programming.
  • Step 5: Test every function after programming—lock, unlock, panic, trunk, and start—before ending the session.
