Transponder keys are devices, which are designed to transmit a radio signal to a remote receiver from a hand-held device. Although they are used in gate opening and keyless entry systems, they are mainly known for unlocking and starting vehicles. Each one of them is programmed to start a particular vehicle and to reduce possibility of theft.
Most of the vehicles that are manufactured after 1996 are fitted with the key transponder system. The reason why car manufacturers got inclined towards using these keys was the readability. Most of chips do not even need the use of batteries and thus there aren’t any moving part. In fact, most of the people do not even realise that there is the transponder chip inside the plastic head of key.
How Does the Transponder Keys Work?
In automotive transponder keys, the transmitter unit generally consists of a small microcip in plastic part of a key. The chip has a serial number that’s unique and this number is set when its initial programming was done. Whenever a person wants to start or unlock a car, the microchip sends a request to the vehicle for it to validate the number and turn off the engine immobilisers. The car will however remain locked & immobilised if it doesn’t recognise the number. Nevertheless, a key, which hasn’t been programmed may still be able to turn the engine over but it won’t be able to start the car.
