Cobra's ConraTrak 5 takes the benefits of several disparate Cobra security systems and bundles them together into one powerful system, which earned it a Category 5 placement in the Thatcham system, which means it must effectively help you recover the vehicle if it's stolen [source: Thatcham]. That means the CobraTrak 5 system, which Cobra calls one of its "top of range systems," features vehicle tracking that works in a very unique way.
An automatic driver recognition (ADR) system forms a link between your car and a card you carry on your person. If the card is outside the car, the ADR system is armed and instantly alerts Cobra's operating center if the car is moved. If a thief somehow makes off with your keys but doesn't grab the ADR card, they're toast: The ADR system will be aware that the card isn't in the vehicle with the car thief. Cobra can also initiate remote engine immobilization. Once a stolen car has been shut off, it won't turn on again. Coupled with GPS tracking, remote engine immobilization increases the chances that police will be able to find and recover a stolen vehicle [source: Cobra].
This is a high-end, pricey security system for car owners who live in Europe. Cobra charges £649 ($1,050) for the system, plus £199 ($322) for an annual monitoring fee [source: Cobra]. If that sounds too rich for your blood, check out our next form of car security. It may not come with GPS tracking or remote engine immobilization, but it will make it a whole lot harder for a carjacker to sell your stolen vehicle to an underground chop shop.
