With this new system, Transponder Car Keys became an element of great value that should be taken care of a lot since they have a chip or transponder built into the head. When the key makes contact with the switch, a signal is transmitted between them. “The computer issues the question and the transponder answers with the car code. If there is no response or it is incorrect, the engine will not start.
In this way, a thief cannot start the vehicle since he cannot start it without having the corresponding key. But with so much technology, some inconveniences also come because of the chip stops working or is not well coded with the car model in question, and it will not start. The same happens in case of loss of the key.

The keys with anti-theft chip began to be introduced by the leading car manufacturers at the end of the 90s, and this system works with a controller called immobilizer, which interacts with the anti-theft chip that is in the head of the key.
To prevent or allow the flow of fuel through the gasoline pump, this system has evolved through every change of generation in cars.
Simply an incoming signal, emitted by a reading antenna: ring around the drum of the starter lock, and which is connected to the central computer. And a tiny antenna that holds the chip captures the signals, which is enough to generate power for said component, to emit its information in this way.
