With more than 4 million installations since 1976, the Ravelco Anti Theft Device is the only device that has never been defeated.


This small device is installed in the dash. Remove the plug and the vehicle will not start. The Ravelco offers an unbeatable combination of sturdy construction, secure technology and ease of use.

How the Ravelco Anti Theft Device works

The Ravelco acts as a keyed electrical interrupt. The Ravelco base unit is installed in or underneath your dash and the wires are routed into the engine compartment. The Ravelco is wired to various electrical components your engine needs to run (such as the ignition, starter, fuel injection system, fuel pump, engine sensors, etc.). We give the owner the ability to prevent the flow of electricity to those systems by removing the plug from the Ravelco base unit.

Designed to work AGAINST the way theives steal cars

Thieves go straight to the car’s weak point to steal it: the wires under the dash. All the wires they need to start the car are there. This is also where EVERY alarm and other theft prevention device is wired.

Inside the passenger compartment thieves are hidden from anyone not looking directly into the car at close range.

The Ravelco is different from other car security devices. Underneath the dash the Ravelco wires are protected with steel, so thieves can’t get access to them. Even if they did, all the wires are the same color, and there is no pattern to give away the pairs.

Theives are forced OUTSIDE the car to work in the open. Inside the engine compartment, all the wires are hidden inside the factory wiring, disguised to look like factory wiring, or put out of view behind engine components. Thieves don’t want to stand outside the car with the hood open, unraveling your car’s electrical system and removing engine compartment components, where it’s obvious they are trying to start the car.

Thieves want to get in your car and be gone within 5 minutes. With a Ravelco installed, they can’t.

Its Genius is in the Simplicity

Truly genius solutions are simple and minimize points of failure. Our straight forward design has been proven reliable and EFFECTIVE at preventing vehicle theft time and time again over the last 32 years.

The Ravelco Anti-Theft Device consists of:

  1. The Ravelco base unit that is installed in your vehicle (note: the Ravelco wires were removed from the photo!)
  2. Two plugs keyed to the base unit (additional plugs can be ordered)
  3. Two warning decals
  4. Two quick disconnect key chains
  5. Custom installation of the Ravelco specifically for your vehicle

The Ravelco is keyed to your car

There are no master plugs for the Ravelco. You can be assured that only your plug will work on your car. With more than 100,000 possible combinations for the Ravelco Anti-Theft Device, the specific physical signature of your vehicle’s plug cannot be guessed.

The base unit is installed in your vehicle, either bracket mounted under the dash, flush mounted in the dash, or concealed from view. When you leave your car, you remove the plug from the Ravelco base unit and attach it to your key chain.

Without the plug, electricity can’t flow to key vehicle components. Because we are disabling various engine components, there is no power draw form the car’s battery, and no need to replace batteries in a remote.

100% Effective and 100% Reliable

It’s not enough that an anti-theft device is 100% effective in preventing thieves from hot wiring your vehicle. You also need the peace of mind that comes from knowing that each and every time you insert the Ravelco plug, the vehicle will start reliably, ensuring that technology designed to prevent theft doesn’t inadvertently prevent operation of your vehicle. The Ravelco is made in the USA of the highest quality metals. The female pins are made out of a memory alloy that always maintains its shape. Ravelco Anti-Theft Devices that were installed 20 years ago are working just as reliably today.

The Ravelco works with other security systems

The Ravelco does not interfere with other alarms or tracking systems installed in your vehicle. No other system is affected by the installation and use of the Ravelco. For owners who want to have multiple layers of protection, an alarm, anti-theft device, and/or a tracking system, the Ravelco is the perfect fit.

Our Lifetime Warranty offers you additional protection

We are so confident in the quality of the Ravelco Anti-Theft Device that we offer a Lifetime Warranty for the original owner. If the system wears out, we’ll replace it for free. To date, we have not had one replacement.
