The Autowatch 443Ti requires a unique touchkey to be pressed into the flush mounted receptacle. Simply press the touchkey to the receptacle and you have 30 seconds to start the vehicle. There is no procedure to rearm as the 443Ti will automatically rearms 30 seconds after the ignition is switched off. An optional hidden switch can be installed for maximum security. With the extra hidden switch installed both the touchkey and the hidden switch must be activated before the 443Ti will disarm.
