Transponder Clone Keys When a car key in the ignition is turned on it transmits an extremely low-level radio signal (called a transponder) to the chip. This signal carries a unique digital serial number that certifies the key as the correct one for that particular vehicle. The system is designed to make it extremely difficult to steal a vehicle since the vehicle will only start when it receives the proper signal from the correct key. Utilizing a key cloning device makes it possible to duplicate keys without having to reprogram the car's computer to recognize the new key. Cloning keys to a car requires two things: a method to extract the data of the original key and a device that can write the data onto a different chip. Currently, most conventional cloning machines work well with a variety of keys. However, some machines work with a limited number of keys of certain brands and types. A cloning system that is reliable will determine not only if there is a chip inside the key, but also what kind of chip it is. This is essential because there are so many varieties and brands of chips used today. When swapping the chips between the key shells, it is easy to mix them up, so a cloning device that can differentiate between them is vital. Advanced systems will include an identification feature that allows them to identify every type of chip.
