2012 Toyota Prius V Smart Key Programming Instructions Keyless Entry Remote Fob

Step-by-Step Guide Important Notice: The 2012 Prius V is equipped with a Smart Key System that does not support manual or onboard programming. All remote fobs must be programmed using advanced diagnostic tools capable of accessing the vehicle's electronic immobilizer and security system.

Programming Procedure:

  • Step 1: Ensure the vehicle is parked with the ignition off and all smart keys are removed from the cabin to prevent unintended signal interference.
  • Step 2: Connect an approved diagnostic scan tool to the vehicle’s OBD-II port, located beneath the dashboard on the driver’s side.
  • Step 3: Turn the vehicle to accessory mode by pressing the START/STOP button twice without pressing the brake. This powers up the electronic modules without starting the engine.
  • Step 4: On the scan tool, navigate to the keyless entry or immobilizer system menu and select the option to register or add a new smart key.
  • Step 5: When prompted, hold the new smart key near the START/STOP button or the designated registration area until the system acknowledges its presence.
  • Step 6: Follow the on-screen instructions to complete the registration. Wait for confirmation via an audible chime or blinking lights to indicate that the key has been successfully programmed.
  • Step 7: Repeat the process for any additional smart keys you wish to program. Make sure each key is individually confirmed by the system.
  • Step 8: Once all desired keys are programmed, close the diagnostic session. Turn off the ignition and disconnect the scan tool.
  • Step 9: Test each smart key for full functionality, including door lock/unlock, push-button start, and trunk access.

Additional Information:

  • If no working smart keys are available, an immobilizer reset procedure may be necessary before new keys can be registered. Be sure to verify that the replacement key fob is fully compatible with the 2012 Prius V Smart Key System. Limit wireless interference during the procedure by removing nearby electronics or mobile devices. The system can store multiple smart keys—check the owner's manual for maximum supported quantity.
