Transponder Chips
Transponder chips are likely be found in cars manufactured within the past 20 years. This is a little plastic piece on the back of your key which contains a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.
When it is activated by an electromagnetic field the chip emits a low-level signal. This signal is then amplified by the specific antenna that is positioned around the ignition barrel of your car. This allows the computer in your vehicle system to determine if the transponder chip that is in the key is the correct one for the car you have.
This is what prevents doing hot-wiring or altering the vehicle's ignition system to start it. The chip inside the key also proves that you are the legal owner of the vehicle. This will help reduce car theft.
Transponder keys resemble regular keys made of metal, but with a plastic cap. The chip is housed inside the plastic portion of the key and there are different kinds of cuts available on these keys: a standard cut laser cut (also called a sidewinder key), or a Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal will then get received by the chip, causing it to transmit a signal back to the car. If the computer inside the car detects the signal as valid it will turn off the car immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder signal as the proper one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This feature is designed to discourage people from attempting to hack into the vehicle, however it's not a 100% security measure. A skilled and determined thief could still evade this system with a specially designed device that detects the signal.

Key fobs are able to communicate with each other and the car using radio frequencies which are transmitted by an antenna in the center of the key. The transmission is encrypted, which helps to prevent others from intercepting and replicating the signal.
Keyfobs can be programmed in a variety of ways depending on the model and make of your car. You can sometimes do this yourself, however most modern automobiles require a dealer or professional locksmith to program a replacement or an additional fob.
When you press a key fob's button it transmits a code to the car's radio that it is linked to. The receiver compares this information to the signals that are allowed on the fob and either opens or locks the door. If the information doesn't match, the car will not be allowed to drive.
When a car is connected with a specific fob it will only accept signals from that specific device. In turn, other fobs will not work with the vehicle even though they appear similar. This protects the integrity of the vehicle's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.
Most newer car dealerships will only deal with cars that have original fobs or genuine replacements offered by the manufacturer. This is because the only place with the experience to design the replacement fob is a dealer's service department. However, some fobs from the aftermarket typically for older models with less sophisticated systems -- can be programmed by customers without the need of dealers.
