In Ford Focus MK3 you can activate anti-hijack feature. Also called as auto-locking. Turn the ignition on, press central lock button on the dashboard 3 times. Turn the ignition off and again press the button 3 times. Turn the ignition back on and you will hear short beep. This means that you are now in programing mode. Now each short press of the button will toggle the auto locking feature and each long press will toggle auto unlocking feature. When you’re done turn the ignition off. Short honk will confirm exiting programing mode.
