Transponder Chips
If your car was manufactured in the past 20 years, chances are it contains a transponder chip within of it. It's the tiny plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your vehicle.
When it is activated by an electro-magnetic field the chip emits a low-level signal. The signal is then amplified by the specific antenna that is positioned around the ignition barrel of your car. This allows the vehicle's computer system to determine if 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 your vehicle to start it. The chip inside the key ensures that the owner is the one who owns the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys appear like regular metal keys but they have a plastic cap. 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 standard cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.
The circuit in the induction coil will emit a signal when the transponder is put into the ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer on the car recognizes 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 the correct signal, it won't start the engine and notify you via flashing lights and an alarm. This system is designed to deter individuals from tampering with the vehicle. However it isn't a foolproof measure of security. A skilled and determined criminal might be able get around this system using a device that can detect the signal.

Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making chirping sounds to help find a car in a parking lot, today's key fobs can also switch on the heated steering wheel or roll down all of the windows with just a single push. Many of these extra features might seem useful, but they can also make it harder for you to keep the keys to your car.
Key fobs utilize radio frequencies to communicate with each other and with the car. These frequencies are transmitted by a small antenna within the middle of the key. This signal is encrypted to block other key fobs from intercepting or replicating the signal.
You can program a keyfob in various ways based on the make and model of your vehicle. It is possible to do this yourself, but the majority of newer cars require that you visit an expert locksmith or dealer to program a replacement or an additional fob.
When you press a key fob's button, the microchip inside transmits a code to the car's receiver it is linked to. The receiver compares this information to the signals that are allowed inside the fob, and either locks or opens the door. If the data doesn't match an chirping sound is heard and the car isn't able to operate.
Once the car is connected to a specific fob, it only accepts signals from the device. Other fobs will not work with the car, despite the fact that they look similar. This helps to protect the integrity of the car's computer system and prevent unauthorised key fobs from taking control of the vehicle.
The majority of newer dealerships will only deal with cars that have original fobs, or genuine replacements offered by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security skills which can only be obtained in the dealer service department. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems can be programmed by the consumer without the need for a dealership.
