How do you reset anti theft system in 2006 ford ranger?

To reset the anti-theft system in a 2006 Ford Ranger, first ensure all doors are closed. Insert the key into the ignition and turn it to the "On" position without starting the engine. Wait for about 10 minutes until the security light turns off, then turn the key to the "Off" position and back to "On" again. This process may need to be repeated a couple of times if the system does not reset on the first attempt.
