Transponder Chips
Transponder chips are likely be found in cars manufactured within the past 20 years. It's the small plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.
When activated by an electro-magnetic field the chip emits a low-frequency signal. This signal is then amplified by the specific antenna that is fitted around the ignition barrel of your car. The computer system of the vehicle will then confirm that the chip in the key's transponder is the correct one for your vehicle.
This is what prevents hot-wiring or tampering with the ignition system of the vehicle to turn it on. The chip in the car key ensures that the owner is the one who is the owner of the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular keys, but with a plastic top. The chip is contained inside the plastic portion of the key, and there are a few different cuts that can be found on these keys: a standard cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal will then get received by the chip and cause it to transmit a signal back to the car. If the computer onboard the car recognizes the signal as correct it will turn off the car immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder signal as being the proper one, it will keep the engine from starting and will alert you by flashing its lights and sounding a siren. This function is designed to discourage people from tampering with the vehicle. However it isn't a foolproof measure of security. A skilled and determined thief could still be able to bypass this system by using a special device to detect the signal.

Key fobs are able to communicate with each other and the car using radio frequencies which are transmitted through an antenna in the center of the key. This communication is encrypted, which helps to stop others from stealing and retransmitting the signal.

When you press the button on a key fob, the microchip transmits an indication to the receiver inside the car with which it is linked. The receiver then compares the data with the 'allowed signals' stored in the key fob, and then locks or opens the car door. If the information isn't in line an chirping sound is heard and the car isn't able to operate.
Once the car is connected to a specific fob, it can only receive signals from that device. In turn, other fobs will not work with the vehicle, even though they look the same. This protects the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.

Some aftermarket fobs, usually those from older models with less sophisticated systems can be programmed with out the need for a dealership.
