Peace of mind
Very professional service. Nothing is ever 100% but this company is. Definitely recommend to everyone I know.

We believe no car should be stolen. With that belief in mind, we sell and install an anti-theft device with an unparalleled track record. The Ravelco Anti-Theft Device has been around since 1976, sold over 5,000,000 units without ever having a vehicle stolen by defeating the device. We can protect your vehicles. About the Ravelco Anti-Theft DeviceThis 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.Designed to work AGAINST the way thieves steal vehiclesThieves go straight to the car’s weak point to steal it: the wires under the dash. Every wire they need to start the car is there. This is also where EVERY alarm and other theft prevention device is wired.Inside the passenger compartment, thieves are hidden from view.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 follow.Thieves 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 components, where anyone can easily see them.Thieves want to get in your car and be gone within 5 minutes. With a Ravelco Anti-Theft Device installed, they can’t.

I think the product is an excellent value for the price. The peace of mind that it gives me is priceless. I only wish that the parts came in a black color so that it would blend in with my very expensive black leather interior. It could blend in much better if it were black. Also, because it's so low under my dashboard, it's difficult to see at night. It would be a nice option to add a a light ring to the exterior of the outlet. Overall, I'm extremely happy with my purchase and the service that I have received. Thank you.

This is a great product! Someone tried to steal my previous Jeep and were unsuccessful thanks to the Ravelco product. The at-home installation makes this purchase so easy!

Very satisfied client here, Sam was able to schedule my GR COROLLA within the week of purchasing my car. Renee did a fantastic job, very meticulous with his work. Explained to me how to use the product. Seriously, the wires are hidden but if you find them… Looks factory👍 Thank you

I have an '05 F-150-easy pickings for thieves. I did a lot of research and came across California and Arizona Ravelco and decided to go with them and have their system installed. The installer, Adam, came right on time and did an excellent job. I feel a sense of relief, knowing that my car is seriously protected now.
