Transponder Chips
If your car was manufactured within the past 20 years, chances are it has a transponder chip inside of it. It's the tiny plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your car.
When it is activated by an electromagnetic field, the chip emits a low-level signal. This signal then gets absorbed by the special antenna that is attached to the ignition barrel of your vehicle. The computer system of the vehicle is then able to verify that the key's transponder chip is the correct one for your vehicle.
This prevents the vehicle from being started by hot-wiring, or by altering the key. The chip inside the key confirms that the owner is the person who owns the vehicle. This can reduce car theft.
Regular transponder keys are designed like regular keys and have a plastic top. The chip itself is housed within the plastic part of the key, and there are different cuts that can be found on these keys: a regular cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.
The circuit in the induction coil emits a signal when the transponder is placed in the the ignition barrel. The signal will be received by the chip, causing it to transmit a signal to the car. If the computer on the car detects this signal as the correct one, it will shut down the immobilizer on the vehicle and allow the engine to start.
If the car isn't able to recognize the transponder as a valid signal, it won't start the engine, and will warn you with flashing lights and a siren. This is designed to discourage people from attempting to alter the vehicle, however it is not a foolproof security measure. A skilled and skilled criminal could still bypass this system by using a specific device that detects the signal.

Key Fobs

Many of these extra features may appear convenient however they could make it more difficult to keep track of your car keys.
Key fobs utilize radio frequencies to connect with one another and the car. These frequencies are transmitted by a small antenna within the middle of the key. The communication is encrypted, which helps to keep others from stealing and retransmitting the signal.
You can program a keyfob in different ways based on the model and brand of your car. Certain models allow you to do this by yourself. However, the majority of newer models require you to visit a professional locksmith or dealer in order to program a new key fob or additional one.
When you press the button on your key fob, the microchip inside transmits an informational code to the car's radio that it is linked to. The receiver compared the information with the 'allowed signals' stored in the key fob and then locks or opens the car door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't permitted to function.
When a car is connected with a particular fob, it will only accept signals from that device. Other fobs will not work with the car, even though they appear similar. This safeguards the integrity of the computer system of 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 that are supplied by the manufacturer. This is because the only place with the knowledge to create a replacement fob is in the service department of the dealer. Some aftermarket fobs, usually those from older models with less sophisticated systems can be programmed without the need for a dealer.
