Not one vehicle ever STOLEN .  .  .

by defeating a properly installed and utilized Ravelco!

Here is how the RAVELCO works . . .

No Bells or Whistles . . . Just Results!

The Ravelco (pronounced Ruh-vel-co) Anti Theft Device is installed in an easily accessible place under or flush mounted in the dashboard. A removable 16 pin male plug (which when not in use connects to your key chain) makes all the electronic connections. A hidden armored steel cable protects the wires from the rear of the RAVELCO base on through to the engine compartment where all the connections are made and camouflaged. When the plug is removed from the RAVELCO, it is impossible to start the vehicle.

The circuits interrupted by the RAVELCO may vary from application to application. Typically, they would include the electronic fuel or injector pump, the ignition circuit, the starter circuit or even the computer.

All electrical connections are made in the engine compartment of the vehicle and are connected in and through the factory wiring harnesses. Since there are no exposed wires, a properly-installed RAVELCO is virtually impossible to detect and very time consuming to trace because all the wires are the same color (black). Even trained, mechanics have called our offices to question the location of the RAVELCO hookup on a vehicle.

A RAVELCO customer is assured that their plug is unique, and that no one else can start their vehicle simply by gaining access to another RAVELCO plug. Competitive products allow only six or fewer possible plug combinations, and each device sold through a particular car dealer will all use the same plug! THIS IS NOT THEFT PROTECTION!

Each Ravelco unit is hand made and tested before leaving our factory. The components used in the manufacturing of the Ravelco Anti Theft Device are all made in the U.S.A. and are of the highest quality, tested for performance, and proven in the field since 1976. Reliability is must and an absolute. Unlike competitive products, a RAVELCO WILL NOT FAIL. In fact, a major selling point of the RAVELCO is its superior performance against that of competitive products. When a competitive product fails, the vehicle on which it is installed will stall and cannot be started. Any car dealer or anti theft device installation facility that has handled a competitive product for any length of time has suffered this embarrassment -- and expense -- of having to send out a tow truck to retrieve a customer's vehicle. NOT SO WITH THE RAVELCO!

The Ravelco Anti Theft Device is superior to all the other alarms and anti theft devices, the reason for this is that the RAVELCO is so simple to use, there are not any codes to remember and there are no secret buttons to push. Whenever you leave your vehicle all you have to do to activate the RAVELCO system is "pull out the plug" and connect it to your key chain. It is like taking part of your engine with you. Many new car buyers do not want all the bells and whistles associated with today's alarm systems because they know that no one pays attention to them! How many times have you heard an alarm going off and noticed people just walk by, minding their own business? Shown recently on a television news program, was a policeman unknowingly assisting a car thief, breaking into a vehicle with a coat hanger and stealing a car. Incidentally, the vehicle's alarm was going off the whole time!

PLEASE NOTE: Your Ravelco Anti Theft Device comes with two windows stickers (shown below). The Ravelco installer will apply these to the front driver's side and front passenger's side windows of your vehicle. The RAVELCO window stickers really do work, as a thief will not even waste their time if they see a RAVELCO warning sticker on your vehicle. If you decide to have your vehicle's windows tinted - Be sure to demand to the person who is applying your window tint to tint OVER the Ravelco window stickers. The reason for this is, if the sticker is put on after the tint is applied, the Ravelco warning window sticker will not be visible at night. Do not let the company or the person tinting your windows tell you that they will not warrant the tint if they tint over the window stickers. Nothing will happen to the tint, it will not bubble if it is done correctly. This is done all the time with no problems at all. If they cannot do it, find another tinter.
