Kill Switch

A Kill Switch Offers Additional Theft Protection
There's never a downside to having a bit of extra protection when you're leaving your vehicle behind in even the safest-looking area. A kill switch does much more than just alert you that a thief is attempting to access your car or truck – it completely eliminates the likelihood that they'll drive away with your vehicle. Find the best kill switches for cars and trucks at AutoZone and keep your ride as secure as possible the next time you lock your doors and head indoors.

Stop the Vehicle
A kill switch protects your vehicle from theft by completely disconnecting it from the battery or otherwise interrupting the combustion system that starts your ride and keeps it moving forward, which prevents the engine from starting and therefore stopping anyone who'd otherwise try to drive away with your car or truck in their tracks. While this is the most popular use for kill switches by far, this same function is also useful in DIY auto repair and upgrade situations. It gives you a way to immediately shut off and power down your vehicle if a dangerous situation happens to arise while you're under the hood or otherwise handling moving parts.

Kill Switch Options
When you search “kill switches near me” in your preferred search engine, you'll find a wide range of different options on our website. Every kill switch serves the function of interfering with your combustion system's components to shut down your vehicle as quickly as possible, but different switches go about the process in different ways. Some interfere with the spark plug, while others overload your engine sensors. Still others might take the route of blocking electricity so it can't complete the process of combustion in the engine. Each of these methods are effective, but each carries its own risks as well. The spark plug interruption, for example, may cause backfiring if there's a large amount of gasoline. The other methods (engine sensor interruption and electrical process interruption) tend to carry fewer negative effects and are generally more effective at ending an engine's operations immediately for either security or safety purposes.
