The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal is then amplified by the specific antenna that is positioned around the ignition barrel of your car. The computer system of the vehicle will then confirm that the key's transponder chip is the right one for your car.
This prevents the vehicle from starting by either hot-wiring or by manipulating. The chip inside the car key confirms that the owner is the one who is the owner of the vehicle. This will help reduce car theft.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out the signal. The signal will be received by the chip, causing it to transmit a signal to the car. If the computer on the car detects this signal as the correct one, it will shut down the vehicle immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder as the correct signal, it will not start the engine and will alert you with flashing lights and siren. This feature is designed to discourage people from trying to alter the vehicle, however it isn't a foolproof security measure.

These additional features can make it difficult for you to locate your car keys.
Key fobs utilize radio frequencies to communicate with each other and the car. These frequencies are transmitted through a small antenna located in the middle of the key. The signal is encrypted to block other key fobs from stealing or modifying the signal.
Keyfobs can be programmed in different ways based on the model and make of your vehicle. Certain cars let you do this yourself. However, the majority of modern models require you to visit an expert locksmith or dealer for them program a replacement key fob, or an alternative one.
When you press a key fob's button, the microchip inside transmits a code to the car's radio that it is paired with. The receiver compares the information with the 'allowed signals' stored in the key fob, and then it opens or closes the car door. If the information does not match, the car will not be allowed to operate.
Once the car is linked with a particular fob, it will only receive signals from that device. In turn, other fobs won't be able to work with the vehicle, even though they appear similar. This protects the integrity of the computer system in the car and blocks unauthorized key fobs gaining control of it.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security expertise that can only be found in the dealer service department. Certain aftermarket fobs, typically those from older models that have less sophisticated systems, can be programmed without the need for a dealer.
