Transponder keys are currently becoming very popular for use in newer cars. Also known as chip keys, these devices go a long way toward increasing vehicle security. For one thing, they’re very hard to copy or duplicate. Secondly, an auto that uses of this type of key makes it extremely difficult for a thief to steal it.

This is how they work. A transponder is an electronic device that’s designed to transmit and respond to an electronic signal… Thus the name. They’ve been around since the 1930’s and were put to good use by aviators during the Second World War. An airplane that was equipped with a transponder was able to be seen by radar operators as a friend rather than a foe.

Transponders continue to be used extensively in aviation today. They are the devices in airplanes responsible for letting the operators in airport control towers know which aircraft are where. They are what make all those little blips on the radar screens, communicating such vital data as direction and altitude.

But they also have many other important uses that affect everyday life. Commuters, for example, may have a transponder installed on their car to talk to the computers used at tollbooths. This makes it possible for the car to proceed through the booth without stopping to pay the toll fee on the spot.

If you own a cell phone, you already have a transponder. Cell phones are required to have these devices built in. That way, if a call is ever made to 9-1-1 from that phone, its location can be easily traced. This can, in some cases, be a lifesaver. Mountain climbers and backpackers might also use one of these gadgets for use in case they get in some kind of trouble and require assistance.

One of the newer developments in transponder technology is in its application to chip keys. The name comes from the fact that there’s a microchip or circuit located in the plastic head of the key that is used to activate the ignition system of the car in which they’re installed. When turned in the ignition lock, these devices will immediately receive a signal from the car’s computer and then respond with its own signal. If the computer receives no response, or if it’s the wrong response, it will refuse to start the vehicle.

Protection from theft is a major concern to car owners and transponder keys make this very feasible. Where once a criminal needed only to gain entry and touch a couple of wires together to steal a car, that’s no longer possible with a system like this. And using a tool to disable the ignition cylinder won’t work anymore either. Without the proper key in hand, there will be no power to go.
