Transponder Chips
If your car was manufactured within the past 20 years, then it has a transponder inside of it. It's a small plastic piece on the back of your key that houses a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then absorbed by the special antenna that is fitted around the barrel that controls your ignition in your car. This allows the computer in your vehicle system to confirm that the transponder chip that is in the key is the right one for the car you have.
This stops the vehicle from being started through hot-wiring, or by altering the key. The chip in the key also proves that you are the genuine owner of the vehicle. This will help reduce the possibility of theft from your vehicle.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer in the car is able to recognize 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 keep the engine from starting and will notify you by flashing its lights and sounding a siren. This feature is intended to discourage people from attempting to tamper with the vehicle, however it's not a 100% security measure. A skilled and determined criminal could still be able to get around this system using a device that can detect the signal.
As you can see there are quite number of benefits to having transponder keys. Every car owner should consider this if they wish to protect their investment and reduce theft risk.
Key Fobs
Key fobs today can do more than just lock and unlock doors. They can also turn on the vehicle remotely, emit chirping sounds to help locate a car or switch on the heated steering wheel. These additional features could make it difficult to find your car keys.
Key fobs communicate with one with the car via radio frequencies which are transmitted by an antenna in the middle of the key. The communication is encrypted, which helps prevent others from intercepting and replicating the signal.
There are several ways to program a key fob depending on the model and make. You can sometimes do this yourself, however most modern vehicles require a dealer or professional locksmith to program a replacement or a second fob.
When you press a key fob's button, the microchip inside transmits a code to the car's radio that it is paired with. The receiver then compares the data with the 'allowed signals' stored in the key fob, and then locks or opens the car door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't able to operate.
Once the car is paired with a specific fob, it will only accept signals from that specific device. As a result, other fobs won't be able to work with the vehicle, even though they look the same. This protects the integrity of the computer system that runs the car and blocks the use of unauthorized key fobs to gain control of it.
Most newer car dealers will only work on a car with original fobs or genuine replacements sold by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security skills that is only available in the dealer service department. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems can be programmed by consumers without the need for an authorized dealer.
