Programming Instructions:
Follow these steps carefully to program your 2012 Toyota Tacoma key fob:
- Ensure all doors are closed and begin with your key removed from the ignition.
- Open and unlock only the driver’s side door. Keep all other doors closed.
- Within 5 seconds of opening the driver’s door, insert your key into the ignition switch and remove it twice in quick succession.
- Next, cycle the driver’s side door by closing and opening it twice.
- Insert the key into the ignition switch and then immediately remove it.
- Again, cycle the driver’s side door by closing and opening it two times.
- Insert the key into the ignition and this time, leave it in the ignition switch.
- Close the driver’s side door.
- Turn the ignition to the “ON” position, then immediately turn it back to the “OFF” position. Do not start the engine.
- Remove the key from the ignition.
- At this point, the door locks should automatically cycle (lock then unlock) once, indicating that your Tacoma has successfully entered programming mode.
- Take your first key fob remote to be programmed. Press and hold both the “LOCK” and “UNLOCK” buttons simultaneously for about 1.5 seconds. Release both buttons. Immediately after releasing, press and hold only the “LOCK” button for 2 seconds.
- The door locks will cycle once again to confirm successful programming of this remote. If you have additional key fobs to program, repeat step 12 with each additional remote. If not, proceed to the final step.
- Open the driver’s side door to finalize the programming sequence. Programming is now complete for your 2012 Toyota Tacoma key fob.
