The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is then absorbed by a special antenna attached to the barrel of ignition. The computer system in the vehicle can then verify that the chip in the key's transponder is the right one for your car.
This prevents the vehicle from being started through either hot-wiring or by manipulating. The chip inside the key also verifies 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 placed in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer onboard the car recognizes the signal as being correct, it will disable vehicle immobilizer so that the engine can start.
If the car doesn't recognize the transponder as the correct signal, it won't start the engine and will warn you with flashing lights and siren. This is designed to deter people from trying to tamper with the vehicle, however it's not a 100% security measure.

Key Fobs

These extra features can make it difficult for you to locate your car keys.

The receiver compares the information with the 'allowed 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 is paired with a specific fob, it will only accept signals from the device that is associated with it. As a result, other fobs won't be able to work with the vehicle, even though they have the same appearance. This ensures the security of the computer system that runs the car key reprogramming and prevents the use of unauthorized key fobs to gain control of it.
The majority of newer dealerships will only work with cars with original fobs or genuine replacements offered by the manufacturer.

However, some fobs from the aftermarket typically for older models that have less sophisticated systems -- can be programmed by customers without the need of an authorized dealer.
