Transponder Chips
If your car was built within the past 20 years, then it has a transponder inside of it. It's a small plastic thing in the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
When it is activated by an electro-magnetic field the chip emits a low-level signal. This signal is then received by a specific antenna that is attached to the barrel of ignition. This allows the car's computer system to verify that the transponder chip inside the key is the right one for the car you have.
This is what stops doing hot-wiring or altering the ignition system of your vehicle to get it started. The chip inside the key confirms that the owner is the one who owns the vehicle. This can reduce car theft.
Transponder keys appear like regular keys made of metal, but with a plastic cap. The chip is inside the plastic portion of these keys. There are various cuts that are a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal will be absorbed by the chip and cause it to transmit a signal back to the car. If the computer inside the car detects the signal as being correct, it will disable vehicle immobilizer so that the engine can start.
If the car does not recognize the transponder signal as the correct one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This is designed to deter people from trying to tamper with the vehicle, however it is not a foolproof security measure. A skilled and determined criminal might be able bypass this system by using a device that can take over the signal.
You can see that a transponder is a great option. Every car owner should consider this if they wish to protect their investment and decrease the risk of theft.
Key Fobs

These additional features can make it difficult to locate your car keys.
Key fobs are able to communicate with each other and the car using radio frequencies that are transmitted through a small antenna located in the center of the key. The communication is encrypted, which helps keep others from stealing and retransmitting the signal.
Keyfobs can be programmed in various ways based on the model and brand of your vehicle. Some cars allow you to do this by yourself. However, most newer models require you to visit an expert locksmith or dealer in order to program a new key fob or an additional one.
When you press the button on your key fob the microchip inside sends an encoded code to the car's radio that it is paired with. The receiver compares this information to the 'allowed' signals inside the fob, and either locks or opens the door. If the information does not match, the car will not be allowed to operate.
Once the car is linked with a specific 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 appear like. This is to safeguard the integrity of the car's computer system and to prevent the use of unauthorized key fobs to gain control of the vehicle.
car key programming and cutting of newer dealers will only work on a car with original fobs or genuine replacements supplied by the manufacturer. It is because the only place that has the knowledge to create the replacement fob is a dealer's service department. Some fobs from the aftermarket, especially ones for older models that have less sophisticated systems can be programmed without the need for a dealer.
