Transponder Chips
If your car was manufactured within the past 20 years, chances are it has a transponder chip inside of it. It's a small plastic piece in the head of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then received by a specific antenna attached to the ignition barrel. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the correct one for your vehicle.
This stops the vehicle from being started by hot-wiring or altering the key. The chip inside the key also proves that you are the legal owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.
Transponder keys look like normal keys but they have caps made of plastic. The chip is contained within the plastic portion of these keys. There are several different cuts: a standard cut, laser cut (also called a sidewinder or Ford Tibbe), and the Ford Tibbe.
A circuit inside the induction coil will emit an electrical signal when the transponder is put into the ignition barrel. The signal will then get received by the chip, causing it to transmit a signal back to the car. If the car's computer recognizes this signal as being the right one, it will turn off the vehicle's immobilizer and allow the engine to begin.
If the car isn't able to recognize the transponder as being the proper signal, it won't start the engine and warn you with flashing lights and siren. This feature is designed to deter people from trying to tamper with the vehicle, however it isn't a foolproof security measure. A skilled and committed thief could still be able to escape this security system by using a special device to detect the signal.

Key fobs communicate with each other and with the car through radio frequencies which are transmitted through an antenna that is located in the middle of the key. programming a car key is encrypted to stop others from stealing or modifying the signal.
You can program a keyfob in different ways based on the model and make of your car. Certain models allow you to do this yourself. However, the majority of modern models require you to visit a professional locksmith or dealer for them program a replacement key fob or additional one.
When you press the button on a key fob, the microchip transmits signals to the receiver in the vehicle with which it is linked. The receiver compared the information with the permitted signals stored on the key fob and then it opens or closes the car's door. If the information doesn't match, the car will not be allowed to operate.
Once the car has been paired with a specific fob, it only accepts signals from that device. Other fobs won't work with the car, even if they appear identical. This is to safeguard the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.
Most newer car dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. This is because the only place that has the knowledge to create a replacement fob is in the service department of the dealer. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems can be programmed by consumers without the need of dealers.
