Transponder Chips
Transponder chips can be found in vehicles manufactured within the last 20 years. It's the tiny piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip that has a unique code to your car.
When it is activated by an electromagnetic field the chip emits a low-level signal. This signal then gets taken up by the antenna that is positioned around the barrel that controls your ignition in your vehicle. This allows the computer in your vehicle system to determine if the transponder chip inside the key is the right one for your particular car.
This stops the vehicle from being started through hot-wiring or manipulating. The chip in the key also proves that you are the genuine owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.

A circuit inside the induction coil will emit an electrical signal when the transponder is placed in the an ignition barrel. The signal is received by the chip which then transmits a signal the vehicle. If the car's computer recognizes this signal as being the right one, it will turn off the immobilizer on the vehicle and allow the engine to start.
If the vehicle doesn't recognize the transponder as the correct signal, it won't start the engine, and will notify you via flashing lights and a siren. This feature is designed to discourage people from attempting to tamper with the vehicle, but it is not a foolproof security measure. A determined and skilled thief could still evade this system by using a specific device that detects the signal.

Key Fobs

These additional features can make it difficult for you to locate your car keys.
Key fobs use radio frequencies to communicate with each other and the car. These frequencies are sent via a small antenna that is located within the middle of the key. The signal is encrypted to prevent others from stealing or modifying the signal.
There are many ways to program a key fob depending on the make and model. Some cars allow you to do this yourself. However, most newer models require you to visit an expert locksmith or dealer to program a replacement key fob or additional one.
When you press a key fob's button, the microchip inside transmits an informational code to the car's receiver it is linked to. The receiver then compares this information to the signals that are allowed in the fob and then either opens or locks the door. If the information doesn't match, the car will not be allowed to operate.
When a car is connected with a particular fob, it will only receive signals from the device that is associated with it. Other fobs will not work with the car, even if they look identical. This safeguards the integrity of the computer system in the car and prevents unauthorized key fobs gaining control over 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 preparing an appropriate replacement fob requires technical and security skills which can only be obtained in the dealer service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
