How do you reset the passive anti theft on a 2003 for explorer?

Press the unlock tab for the driver's side door. Insert the key in the ignition and cycle the switch from off to run 8 times quickly. On the eight cycle, with the key in the run position, press any button on your keyless remote. Wait until the locks are done cycling and release the remote. Switch the ignition off and wait for one last click. The anti-theft will be reset.
