Transponder Chips
Transponder chips can be found in cars manufactured within the last 20 years. This is the little plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is absorbed by a special antenna that is attached to the ignition barrel. The computer system of the vehicle will then confirm that the transponder chip of the key is the correct one for your car.
This is the reason why doing hot-wiring or altering the ignition system of your vehicle to turn it on. The chip inside the key also confirms that you are the legal owner of the vehicle. This will help reduce car theft.
Regular transponder keys are designed like regular metal keys with an outer layer of plastic. The chip is contained within the plastic part of the keys. There are a variety of cuts such as a standard cut a Laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer on the car detects this signal as the correct one, it will shut down the vehicle immobilizer and allow the engine to begin.
If the car doesn't recognize the transponder as a valid signal, it will not start the engine and will notify you via flashing lights and siren. This function is designed to discourage people from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and committed thief could still be able to escape this security system by using a special device to intercept the signal.

Key fobs today can do more than just lock and unlock doors. They can also start the car remotely, emit chirping sounds to help locate the car or turn on the heated steering wheel. These extra features can make it difficult for you to locate your car keys.
Key fobs make use of radio frequencies to communicate with one another and with the car. car keys cutting and programming are transmitted via a small antenna that is located within the middle of the key. This communication is encrypted to prevent others from intercepting or replicating the signal.
There are a few different ways to program a key fob depending on the vehicle's model and make. Certain cars let you do this by yourself. However, the majority of modern models require you to visit a professional locksmith or dealer in order for them program a replacement key fob, or an alternative one.
When you hit the button on a key fob the microchip inside sends an informational code to the car's radio that it is paired with. The receiver then compares this information to the 'allowed' signals in the fob and then either opens or locks the door. If the information doesn't match, the car will not be allowed to operate.
Once the car is associated with a particular fob, it will only accept signals from the device. In turn, other fobs won't be able to work with the vehicle even though they look the same. This ensures the security of the computer system that runs the car and blocks unauthorised key fobs from taking control over it.
Most newer car dealers will only work on cars with original fobs or genuine replacements sold by the manufacturer. The reason for this is that the only place with the experience to design an appropriate replacement fob is the service department of a dealer. However, some fobs from the aftermarket typically for older models with less sophisticated systems -- can be programmed by consumers without the need of dealers.
