2012 Scion xB Smart Key Remote Fob Programming Instructions

Important Note: These instructions apply only to the remote (keyless entry) portion of the Remote Head Key. The mechanical key blade and immobilizer chip must be cut and programmed by a qualified automotive technician.

The system supports four programming modes:

Confirmation Mode – Displays the number of remotes currently registered.

Add Mode – Allows a new remote to be added without deleting existing ones.

Rewrite Mode – Erases all previously registered remotes and programs new ones.

Prohibition Mode – Clears all remotes and disables the wireless lock function.

Confirmation Mode – Check Number of Registered Remotes Start with the driver’s door open and unlocked. Keep the key out of the ignition.

  • Step 1: Insert the key into the ignition, then remove it.
  • Step 2: Within 5 seconds, repeat Step 1.
  • Step 3: Within 40 seconds, close and open the driver’s door twice, then insert and remove the key again.
  • Step 4: Within 40 more seconds, close and open the driver’s door twice, insert the key, and close the driver’s door.
  • Step 5: Turn the ignition switch from LOCK to ON to OFF three times, pausing one second at each position.
  • Step 6: Remove the key. The doors will lock and unlock repeatedly.

The number of cycles indicates how many remotes are programmed. If the doors cycle five times, there are no remotes registered. Add Mode – Add a Remote Without Affecting Existing Ones Start with the key out of the ignition and the driver’s door open and unlocked.
