Transponder Chips
Transponder chips can be found in cars manufactured within the last 20 years. It's a tiny plastic piece inside the head of your key which contains a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
When activated by an electro-magnetic field the chip emits a low level signal. The signal is absorbed by a special antenna attached to the ignition barrel. The computer system in the vehicle is then able to verify that the chip in the key's transponder is the right one for your car.
This is what stops doing hot-wiring or altering the vehicle's ignition system to get it started. The chip in the car key verifies that the owner is the one who owns the vehicle. This can help to reduce the possibility of theft from your vehicle.

The circuit in the induction coil will emit signals when the transponder is inserted into the ignition barrel. The signal will then get taken up by the chip, causing it to transmit a signal back to the car. If the computer in the car detects the signal as being correct, it will disable vehicle immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder signal as being the right one, it will stop the engine from running and will alert you by flashing its lights and sounding a siren. This function is designed to discourage individuals from tampering with the vehicle. However, it is not a foolproof measure of security.

Key fobs make use of radio frequencies to communicate with each other and with the car. The frequencies are transmitted through a small antenna located in the middle of the key. This communication is encrypted to stop others from stealing or stealing the signal.
There are a few different ways to program a key fob, based on your vehicle's model and make. You may be able to do it yourself, but the majority of newer cars require that you visit an expert locksmith or dealer to program a replacement or a second fob.
When you press the button on a key fob the microchip transmits a signal to the receiver in the vehicle with which it is paired. The receiver compares the information with the permitted signals stored in the key fob, and then opens or locks the car door. If the information doesn't match, the car will not be allowed to operate.
When a car is connected with a specific fob, it will only receive signals from the device that is associated with it. Other fobs will not work with the car, despite the fact that they appear similar. This protects the integrity of the car's computer system and to prevent the use of unauthorized key fobs to gain control of the vehicle.
