Transponder Chips
Transponder chips can be found in vehicles manufactured in the last 20 years. It's the tiny plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your car.
When it is activated by an electro-magnetic field the chip emits a low-level signal. The signal is then absorbed by a special antenna that is attached to the ignition barrel. The computer system in the vehicle can then verify that the key's transponder chip is the right one for your car.
This is the reason why from modifying or hot-wiring the ignition system of the vehicle to turn it on. The chip in the key also proves that you are the legal owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.

A circuit within the induction coil emits an electrical signal when the transponder key programmer is put into an ignition barrel. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer onboard the car recognizes the signal as valid it will turn off the vehicle immobilizer, allowing the engine to start.
If the vehicle doesn't recognize the transponder as the correct signal, it will not start the engine and warn you with flashing lights and siren. This feature is intended to deter people from trying to tamper with the vehicle, but it's not a 100% security measure. A skilled and determined criminal may still be able to escape this security system by employing a device designed to take over the signal.
As you can see there are quite number of advantages to having a transponder key. Every car owner must take this into consideration if they wish to protect their investment and decrease the risk of theft.
Key Fobs

These extra features could make it difficult to locate your car keys.
Key fobs use radio frequencies to communicate with each other and the car. These frequencies are sent by a small antenna in the middle of the key. The signal is encrypted to prevent others from intercepting or replicating the signal.
You can program a keyfob in various ways based on the model and make of your vehicle. Certain cars let you do this yourself. However, most newer models require you to visit a professional locksmith or dealer in order for them program a replacement key fob or an additional one.
When you hit the button on a key fob the microchip inside sends an encoded code to the car's receiver that it is paired with. The receiver compares the information with the 'allowed signals' that are stored in the key fob and then it opens or closes the car's doors. If the information does not match, the car will not be allowed to operate.
Once the car is associated with a particular fob, it will only accept signals from that device. As a result, other fobs won't work with the vehicle, even though they look the same. This helps to protect the integrity of the car's computer system and to prevent unauthorised key fobs from taking control of the vehicle.
The majority of newer dealers will only work on a car with original fobs or genuine replacements offered by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security expertise which can only be obtained in the dealer's service department. Some aftermarket fobs, usually those from older models that have less sophisticated systems, can be programmed without the need for a dealer.
