Theft Prevention At Its Simplest You can help prevent thieves from stealing your 911. Nearly 90% of the 911s stolen are taken by yanking out the ignition lock tumbler with a slide hammer. The only thing holding this tumbler in place is a soft aluminum stake pin and a weak plastic bezel. Even a clumsy thief can steal a 911 in less than a minute! We have the solution. Made from aircraft-strength aluminum, Ignition-Loc is many times stronger than any force a slide hammer can exert upon it, making your car a lot tougher to steal. In fact, Ignition-Loc is so effective, its difficult to remove once installed. But thats why its so good! European Car tested our Ignition-Loc and judged it a simple and effective anti-theft device. Install an Ignition-Loc and keep your Porsche home at night!
