Transponder Chips
If your car was manufactured within the past 20 years, then it contains a transponder chip within of it. This is the little plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own.
When activated by an electro-magnetic field the chip emits a low-level signal. The signal is then absorbed by a special antenna attached to the barrel of ignition. This allows the vehicle's computer system to verify that the transponder chip that is in the key is the right one for your particular car.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out a signal. The signal is received by the chip which sends a signal to the vehicle. If the computer in the car is able to recognize the signal as valid it will turn off the car immobilizer so that the engine can start.

Key fobs communicate with each other and the car using radio frequencies which are transmitted by an antenna that is located in the center of the key. This signal is encrypted to stop others from stealing or modifying the signal.

The receiver compared the information with the permitted signals stored in the key fob and then it opens or closes the car's door. If the information does not match, the car will not be allowed to drive.
Once the car has been connected to a specific fob, it will only accept signals from that device. Other fobs will not work with the car, despite the fact that they appear similar. This protects the integrity of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control over it.
