Transponder Chips
If your car was built in the past 20 years, then it has a transponder chip inside of it. It's a tiny plastic piece in the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
When it is activated by an electro-magnetic field, the chip emits a low-level signal. This signal is then amplified by the specific antenna that is fitted around the ignition barrel of your vehicle. This allows the car's computer system to verify that the transponder chip in the key is the right one for your specific vehicle.
This stops the vehicle from starting by hot-wiring, or by altering the key. The chip inside the key also verifies that you are the genuine owner of the vehicle. This will help reduce car theft.

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 absorbed by the chip and cause it to transmit a signal back to the car. If the computer in the car recognizes the signal as being correct, it will disable vehicle immobilizer to allow the engine start.
If the vehicle does not recognize the transponder signal as the right one, it will stop the engine from running and will alert you by flashing its lights and sounding siren. This feature is designed to discourage those who would attempt to alter the vehicle. However it's not an absolute security measure.

The receiver then compares the data with the 'allowed signals' stored in the key fob and then opens or locks the car's door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to operate.
Once the car is linked with a particular fob, it will only accept signals from that specific device. Other fobs won't work with the car, even if they appear similar. This helps to protect the integrity of the vehicle's computer system and prevent unauthorized key fobs from gaining control of the vehicle.
The majority of car dealers who are newer 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 which can only be obtained in the dealer's service department. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems can be programmed by consumers without the need of a dealership.
