Transponder Chips
Transponder chips are likely be found in cars that were manufactured within the last 20 years. It's the small piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your car.
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 barrel that controls your ignition in your vehicle. This allows the car's computer system to confirm that the transponder chip inside the key is the correct one for your specific vehicle.
This is what stops from modifying or hot-wiring the ignition system of your vehicle to get it started. The chip inside the key confirms that the owner is the one who is the owner of the vehicle. This helps to prevent 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 the signal. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer onboard the car recognizes the signal as correct it will turn off the car immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder signal as the correct one, it will prevent the engine from starting and will notify you by flashing its lights and sounding siren. This feature is designed to discourage individuals from tampering with the vehicle. However it isn't an unbreakable security measure. A determined and skilled thief could still bypass this system with a specially designed device that detects the signal.

Key Fobs

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

There are a few different ways to program a key fob, based on the model and make. You can sometimes do this yourself, however most modern cars require that you visit an expert locksmith or dealer to program a replacement or an additional fob.
When you press the button on a key fob, the microchip transmits a signal to the receiver inside the vehicle with which it is linked. The receiver compares the information with the 'allowed signals' that are stored on the key fob and then opens or locks the car's doors. If the information isn't in line an chirping sound is heard and the car isn't permitted to operate.
Once the car has been associated with a particular fob, it can only receive signals from the device. As a result, other fobs won't be able to work with the vehicle, even though they have the same appearance. This protects the integrity of the vehicle's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.

This is due to the fact that preparing the replacement fob is a process that requires technological and security skills that can only be found in the dealer service department. However, some aftermarket fobs typically for older models that have less sophisticated systems can be programmed by consumers without the need of a dealership.
