CarProtect Steering Wheel Lock Australia is a mechanical vehicle-security accessory designed to provide an additional physical barrier when a car is parked. Unlike electronic security systems that rely on alarms, immobilisers or tracking technology, a steering-wheel lock is visible from outside the vehicle and is intended to make unauthorised use more difficult.
A steering-wheel lock should be viewed as one layer of vehicle security rather than a guarantee against theft. Australian automotive testing has shown that even substantial steering locks can sometimes be defeated with power tools, so the main advantages are deterrence and adding another obstacle.
