Transponder Chips
If your car was built in the last 20 years, chances are it contains a transponder chip within of it. This is the little piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to your vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is positioned around the barrel that controls your ignition in your car. The computer system in the vehicle will then confirm that the transponder chip of the key is the right one for your car.
This is the reason why doing hot-wiring or altering the ignition system of your vehicle to turn it on. The chip in the key also verifies that you are the genuine owner of the vehicle. This helps to prevent car theft.
Transponder keys resemble regular metal keys but have a plastic cap. The chip is located inside the plastic part of these keys. There are a variety of cuts that are a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe), and the Ford Tibbe.
The circuit in the induction coil will emit signals when the transponder is inserted into ignition barrel. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer onboard the car detects the signal as being correct, it will disable vehicle immobilizer to allow the engine start.
If the vehicle does not recognize the transponder signal as being the proper one, it will stop the engine from starting and will notify you by flashing its lights and sounding siren. This function is designed to discourage those who would attempt to alter the vehicle. However, it is not an unbreakable security measure. A skilled and determined thief could still be able to escape this security system by using a device that can take over the signal.
It is evident that a transponder is a great option. Every car owner must take this into consideration in order to safeguard their investment and reduce the risk of theft.
Key Fobs

These extra features could make it difficult to locate your car keys.
Key fobs are able to communicate with each other and with the car through radio frequencies which are transmitted by an antenna in the center of the key. This communication is encrypted to stop others from stealing or modifying the signal.
Keyfobs can be programmed in various ways based on the model and brand of your car. Some cars allow you to do it yourself. However, most newer models require you to visit a professional locksmith or dealer in order to program a new key fob, or an alternative one.

When you press a key fob's button it transmits an informational code to the car's receiver that it is paired with. The receiver compares the information with the permitted signals stored in the key fob and then locks or opens the car's doors. If the data doesn't match an chirping sound is heard and the car isn't able to operate.
Once the car is linked with a specific fob it will only accept signals from the device that is associated with it. Other fobs will not work with the car, even if they look like. This protects the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.
Most dealerships with newer cars will only deal with cars that have original fobs or genuine replacements offered by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security knowledge which can only be obtained in the dealer service department. However, some aftermarket fobs -- usually those for older models with less sophisticated systems can be programmed by the consumer without the need for a dealership.
