Abstract
The apparatus is a vehicle lock designed to prevent motor vehicle theft as well as protect costly items such as car stereos. The apparatus locks the driver's seat of a vehicle in a forward position, utilizing the existing components of a conventional seat back adjustment device while adding a minimal number of additional parts. Thieves are prevented from sitting in the driver's seat, thereby preventing the vehicle from being stolen.
