Transponder Chips
If your car was manufactured within the past 20 years, then it has a transponder chip inside of it. This is a little plastic thing on the back of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is absorbed by a special antenna attached to the ignition barrel. The computer system of the vehicle can then verify that the key's transponder chip is the correct one for your car.
This is what stops from modifying or hot-wiring the ignition system of your vehicle to start it. The chip inside the key also verifies that you are the genuine owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is located inside the plastic part of the keys. There are various cuts such as a standard cut laser cut (also known as a sidewinder or Ford Tibbe), and a Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer onboard the car recognizes the signal as valid, it will disable vehicle immobilizer, allowing the engine to start.
If the car does not recognize the transponder signal as being the correct one, it will prevent the engine from running and will alert you by flashing its lights and sounding a siren. This feature is designed to discourage people from attempting to hack into the vehicle, but it's not a 100% security measure. A skilled and determined criminal might be able get around this system employing a device designed to intercept the signal.

Key fobs utilize radio frequencies to connect with one another and with the car. These frequencies are transmitted by a small antenna in the middle of the key. This communication is encrypted, which helps to prevent others from intercepting and re-transmitting the signal.
Keyfobs can be programmed in various ways based on the model and make of your vehicle. Certain models allow you to do it 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 the button on a key fob the microchip transmits a signal to the receiver in the vehicle with which it is linked. The receiver compared this information to the 'allowed' signals stored inside the fob, and either opens or locks the door. If the data does not match the fob's information, the car won't be allowed to run.
Once the car is connected to a specific fob, it can only receive signals from that device. Other fobs won't work with the car, even though they appear identical. This is to safeguard the integrity of the vehicle's computer system, and also to stop the use of unauthorized key fobs to gain control of the vehicle.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer. The reason for this is that the only place with the knowledge to create the replacement fob is the service department of a dealer. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems -- can be programmed by consumers without the need of an authorized dealer.
