Transponder Chips
Transponder chips can be found in cars that were manufactured within the past 20 years. It's a small plastic thing in the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
When activated by an electro-magnetic field the chip emits a low-level signal. This signal is then absorbed by a special antenna attached to the ignition barrel. The computer system in the vehicle will then confirm that the key's transponder chip is the correct one for your car.
This prevents the vehicle from being started by either hot-wiring or by altering the key. The chip in the car key verifies that the owner is the person who is the owner of the vehicle. This can reduce car theft.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out a signal.
car key reprogramming cost will then get received by the chip and cause it to transmit a signal back to the car. If the computer on the car recognizes this signal as being the correct one, it will turn off the immobilizer on the vehicle and allow the engine to start.

This feature is designed to discourage people from trying to hack into the vehicle, however it's not a 100% security measure. A determined and skilled thief could still bypass this system using a special device that blocks the signal.

When you press a key fob's button, the microchip inside transmits an encoded code to the car's receiver that it is paired with. The receiver then compares the data with the 'allowed signals' that are stored in the key fob, and then opens or locks the car's doors. If the information does not match the fob's information, the car won't be allowed to run.
After the car has been paired with a specific fob, it can only receive signals from that device. Other fobs won't work with the car, even though they look similar. This protects the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.
