Transponder Chips
If your car is made in the last 20 years, it is likely that it has a transponder chip inside of it. This is a little plastic thing in the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is then amplified by the specific antenna that is attached to the ignition barrel of your vehicle. The computer system of the vehicle will then confirm that the key's transponder chip is the right one for your car.
This is what prevents doing hot-wiring or altering the ignition system of your vehicle to get it started. The chip in the key also confirms that you are the genuine owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.

A circuit inside the induction coil will emit a signal when the transponder is placed in the the ignition barrel. The signal will then get absorbed by the chip, causing it to transmit a signal to the car. If the onboard car computer recognizes this signal as the right one, it will turn off the vehicle's immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder signal as the correct one, it will stop the engine from starting and will notify you by flashing its lights and sounding a siren. This feature is designed to discourage individuals from tampering with the vehicle. However, it is not an absolute security measure. A skilled and determined thief can still get around this system with a specially designed device that intercepts the signal.
As you can see there are quite a number of advantages to having transponder keys. Every car owner should take this into consideration if they wish to protect their investment and decrease the chance of theft.
Key Fobs

Key fobs communicate with each other and the car using radio frequencies which are transmitted through an antenna that is located in the middle of the key. This signal is encrypted to block other key fobs from stealing or stealing the signal.

When you hit the button on a key fob, the microchip inside transmits an informational code to the car's receiver that it is linked to. The receiver then compares this information to the 'allowed' signals in the fob and then either locks or opens the door. If the data does not match, the car will not be allowed to operate.
After the car has been 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 like. This is to safeguard the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control of the vehicle.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security knowledge that is only available in the dealer service department. Some fobs from the aftermarket, especially ones for older models that have less advanced systems can be programmed with out the need for a dealer.
