What is a transponder key?
Transponder keys provide an extra security to your car. They contain a very small computer chip inside them which is used to authenticate the original car key and the duplicated car key. When you plug it into the ignition, the Engine Control Unit (ECU) will send a coded message to the key.
The key, if it is an original one, will receive the coded message and will respond back to the Engine Control Unit. Only once when the messages are authenticated by the car, your car will start. With these transponder key, the car key replacements have become a difficult job for the automotive locksmith.
Transponder keys do not have a battery; it is an embedded chip which is powered by the radio signals itself that are sent by the car. The radio signals are of a very low strength that they activate the chip only when the key is very near to the dashboard or when it is pushed into the ignition to start the car.
