Transponder Chips
Transponder chips are likely be found in cars that were manufactured within the last 20 years. It's the small plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for your vehicle.
When it is activated by an electromagnetic field, the chip emits a low-frequency signal. This signal then gets amplified by the specific antenna that is positioned around the barrel that controls your ignition in your vehicle. This allows the computer in your vehicle system to confirm that the transponder chip in the key is the right one for your specific vehicle.
This is what prevents from modifying or hot-wiring the ignition system of the vehicle to get it started. The chip inside the car key confirms that the owner is the person who is the owner of the vehicle. This helps to prevent car theft.
Regular transponder keys are designed like regular keys and have an outer layer of plastic. The chip is inside the plastic portion of the keys. There are several different 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 inserted in the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal is received by the chip which then transmits a signal to the vehicle. If the computer onboard the car is able to recognize the signal as valid, it will disable vehicle immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder signal as being the correct one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This function is designed to discourage individuals from tampering with the vehicle. However it isn't a foolproof measure of security. A determined and skilled thief could still evade this system using a special device that intercepts the signal.

Key fobs today offer more than locking and unlock doors. They can also start your vehicle remotely, emit chirping sounds to help locate a car, or switch on the heated steering wheel. These additional features could make it difficult to find your car keys.
Key fobs make use of radio frequencies to communicate with each other and with the car. These frequencies are sent through a small antenna located within the middle of the key. This communication is encrypted to prevent others from intercepting or replicating the signal.
There are many ways to program a key fob, based on the make and model. automotive key programmer let you do this by yourself. However, the majority of newer models require you to visit an expert locksmith or dealer in order to program a replacement key fob or an additional 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 linked to. The receiver compares the information with the 'allowed signals' that are stored in the key fob and then opens or locks the car door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't permitted to operate.
Once the car is linked with a specific fob it will only accept signals from the device that is associated with it. Other fobs will not work with the car, despite the fact that they look identical. This protects the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
Most newer car dealerships will only deal with cars with original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security expertise that can only be found in the dealer's service department. Some fobs from the aftermarket, especially those from older models that have less sophisticated systems can be programmed without the need for a dealership.
