Transponder Chips
Transponder chips are likely to be found in cars that were manufactured within the past 20 years. This is the little plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your car.
When activated by an electro-magnetic field, the chip emits a low-frequency signal. This signal then gets amplified by the specific antenna that is attached to the ignition barrel of your car. This allows the vehicle's computer system to confirm that the transponder chip that is in the key is the correct one for your particular car.
This is what prevents hot-wiring or tampering with 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 can reduce car theft.
Transponder keys look like regular metal keys but they have caps made of plastic. The chip is located inside the plastic portion of the keys. There are several different cuts: a standard cut, laser cut (also known as a sidewinder or Ford Tibbe), and the Ford Tibbe.
A circuit inside the induction coil will emit an electrical signal when the transponder is inserted into an ignition barrel. The signal will then get absorbed by the chip and cause it to transmit a signal to the car. If the computer inside the car detects the signal as being correct it will turn off the car immobilizer to allow the engine start.
If the vehicle does not recognize the transponder signal as being the correct one, it will keep the engine from running and will alert you by flashing its lights and sounding a siren. This feature is designed to deter people from trying to alter the vehicle, however it is not a foolproof security measure. A skilled and determined thief can still get around this system by using a specific device that intercepts the signal.

Key Fobs
Key fobs today offer more than locking and unlock doors. They can also turn on the vehicle from a distance, make chirping sounds to aid in finding cars, or turn on the heated steering wheel. These additional features can make it difficult to find your car keys.
Key fobs are able to communicate with each other and the car using radio frequencies which are transmitted via an antenna in the middle of the key. The signal is encrypted to prevent others from intercepting or replicating the signal.
You can program a keyfob in different ways based on the model and brand of your car. Some cars allow you to do this by yourself. However, most newer models require you to visit a professional locksmith or dealer for them program a replacement key fob, or an alternative one.
When you press the button on your key fob the microchip inside sends a code to the car's receiver that it is linked to. The receiver compared the information with the permitted signals stored in the key fob, and then it opens or closes the car door. If the information doesn't match the signals, the car will not be allowed to operate.
Once the car has been paired with a specific fob, it can only receive signals from that device. Other fobs won't work with the car, even though they look identical. This protects the integrity of the computer system that runs the car and prevents unauthorized key fobs gaining control of it.
Most newer car dealerships will only accept vehicles that have original fobs or genuine replacements offered by the manufacturer. This is because the only place that has the experience to design an appropriate replacement fob is the service department of the dealer. Certain aftermarket fobs, typically those from older models that have less advanced systems can be programmed without the need for a dealership.
