Just added this product to the website recently:
Slow down a potential joy rider or thief with this simple push button device. This device interrupts power going to the starter, when a thief tries to start the car it acts like there is a dead battery and won't crank. With the button pressed in the car operates like normal. Button will light up, it can be wired up to light up when pressed, all the time or when lights come on. Includes detailed instructions. Device can be added to an alarm or used by itself. Uses a high quality relay so power isn't running thru the small button which allows you to mount the button where you want, button can be installed in the glove box, ash try, center console, under the dash or where you choose.
