Transponder Chips
Transponder chips are likely be found in cars manufactured in the last 20 years. This is a little plastic piece in the head of your key which contains a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is positioned around the ignition barrel of your vehicle. The computer system in the vehicle will then confirm that the key's transponder chip is the correct one for your car.
This is what stops doing hot-wiring or altering the ignition system of your vehicle to start it. The chip inside the key also proves that you are the legal owner of the vehicle. This will help reduce car theft.
Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip itself is housed in the plastic portion of the key, and there are different kinds of cuts available on the keys: a cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
A circuit within the induction coil emits a signal when the transponder is put into ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer inside the car is able to recognize the signal as being correct it will turn off the vehicle immobilizer, allowing the engine to start.
If the vehicle doesn't recognize the transponder signal as being the correct one, it will prevent the engine from running and will notify you by flashing its lights and sounding siren. This feature is designed to discourage people from tampering with the vehicle. However it's not a foolproof measure of security. A determined and skilled thief could still evade this system using a special device that blocks the signal.

Key Fobs

Key fobs make use of radio frequencies to connect with one another and the car. The frequencies are transmitted by a small antenna inside the middle of the key. This signal is encrypted to stop others from stealing or stealing the signal.
There are many ways to program a key fob based on your vehicle's make and model. You can sometimes do this yourself, however most modern vehicles require a locksmith shop or a professional to program a replacement or an additional fob.
When you press the button on a key fob the microchip transmits an indication to the receiver inside the vehicle that it is paired. The receiver compares the information with the 'allowed signals' that are stored in the key fob, and then opens or locks the car's doors. If the information doesn't match the signals, a chirping sound can be heard and the car isn't permitted to operate.
When a car is connected with a particular fob, it will only receive 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 appear similar. This ensures the security of the computer system in the vehicle and stops unauthorized key fobs gaining control over it.
The majority of newer dealerships will only deal with vehicles that have original fobs, or genuine replacements offered by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security skills which can only be obtained in the dealer's service department. Some fobs from the aftermarket, especially ones for older models that have less sophisticated systems, can be programmed without the need for a dealer.
