Transponder Chips
If your car is made in the last 20 years, then it contains a transponder chip within of it. It's a small piece of plastic on the back of your key that contains an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then absorbed by the special antenna that is attached to the barrel that controls your ignition in your vehicle. This allows the vehicle's computer system to determine if the transponder chip that is in the key is the correct one for your particular car.
This stops the vehicle from being started by hot-wiring or altering the key. The chip inside the key verifies that the owner is the person who owns the vehicle. This will help reduce car theft.
Regular transponder keys are designed like regular metal keys with a plastic top. The chip is housed inside the plastic portion of the key and there are a few different kinds of cuts available on these keys: a cut laser cut (also known as a sidewinder key) or Ford Tibbe key.
A circuit within the induction coil will emit a signal when the transponder is put into ignition barrel. The signal is received by the chip which sends a signal to the vehicle. If the onboard car computer recognizes this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to begin.
If the car isn't able to recognize the transponder as the correct signal, it will not start the engine and notify you via flashing lights and an alarm. This function is designed to discourage people from tampering with the vehicle. However, it is not an unbreakable security measure. A skilled and committed thief might be able bypass this system by employing a device designed to take over the signal.

Key Fobs

Many of these extra features may seem convenient however they could make it harder for you to keep the keys to your car.
Key fobs communicate with one with the car via radio frequencies which are transmitted through a small antenna located in the center of the key. This communication is encrypted to block other key fobs from intercepting or replicating the signal.
You can program a keyfob in various ways based on the model and brand of your car. It is possible to do this yourself, but the majority of newer vehicles require a locksmith shop or a professional to program a replacement or additional fob.
When you press the button on your key fob it transmits a code to the car's radio that it is linked to. The receiver compares the information with the permitted signals stored on the key fob and then opens or locks the car's doors. If the information does not match the signals, the car will not be allowed to operate.
After the car has been connected to a specific fob, it only accepts signals from that device. Other fobs won't work with the car, even if they look like. This ensures the security of the computer system in the vehicle and stops unauthorized key fobs gaining control of it.
Most dealerships with newer cars will only deal with cars with original fobs, or genuine replacements supplied by the manufacturer. The reason for this is that the only place with the knowledge to create an appropriate replacement fob is a dealer's service department. Certain aftermarket fobs, typically those from older models with less advanced systems, can be programmed without the need for a dealer.
