Transponder Chips
If your car was manufactured within the past 20 years, it is likely that it has a transponder inside of it. It's a tiny piece of plastic inside the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then received by a specific antenna that is attached to the barrel of ignition. The computer system in the vehicle is then able to verify that the key's transponder chip is the correct one for your car.
This is the reason why hot-wiring or tampering with the ignition system of your vehicle to start it. The chip inside the key ensures that the owner is the person who is the owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.

A circuit inside the induction coil emits an electrical signal when the transponder is placed in the an ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer in the car detects the signal as correct it will turn off the car immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder signal as being the proper one, it will keep the engine from running and will notify you by flashing its lights and sounding siren. This is designed to discourage people from attempting to tamper with the vehicle, but it isn't a foolproof security measure. A skilled and determined thief can still get around this system with a specially designed device that intercepts the signal.

Key fobs communicate with one other and with the car through radio frequencies which are transmitted through an antenna in the middle of the key. This communication is encrypted, which helps prevent others from intercepting and replicating the signal.
There are a few different ways to program a key fob based on your vehicle's make and model. You can sometimes do this yourself, however most modern cars require that you visit a locksmith shop or a professional to program a replacement or additional fob.
When you press a key fob's button the microchip inside sends an encoded code to the car's receiver it is linked to. The receiver then compares the data with the 'allowed signals' that are stored in the key fob and then locks or opens the car door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't able to function.
When a car is connected with a specific fob, it will only receive signals from that device. Other fobs will not work with the car, despite the fact that they appear like. This ensures the security of the computer system in the car and prevents the use of unauthorized key fobs to gain control of it.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. This is because the process of creating a replacement fob requires technological and security knowledge that can only be found in the dealer's service department. Some fobs from the aftermarket, especially ones for older models with less advanced systems can be programmed without the need for a dealer.
