Transponder Chips
Transponder chips are likely to be found in vehicles manufactured in the last 20 years. It's the small piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your car.
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 ignition barrel of your car. This allows the vehicle's computer system to verify that the transponder chip in the key is the correct one for the car you have.
This prevents the vehicle from starting by either hot-wiring or by altering the key. The chip in the car key verifies that the owner is the one who is the owner of the vehicle. This will help reduce car theft.
Transponder keys resemble regular keys made of metal but they have a plastic cap. The chip is contained within the plastic part of the key, and there are different types of cuts on these keys: a regular cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.
The circuit in the induction coil emits an electrical signal when the transponder is inserted into the ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer in the car recognizes the signal as correct it will turn off the vehicle immobilizer so that the engine can start.
If the vehicle does not recognize the transponder signal as being the right one, it will stop the engine from starting and will alert you by flashing its lights and sounding an alarm. This function is designed to discourage people from tampering with the vehicle. However it isn't an unbreakable security measure. A determined and skilled thief can still get around this system by using a specific device that blocks the signal.

A lot of these additional features may seem convenient however they could make it difficult for you to keep track of your car keys.
Key fobs utilize radio frequencies to connect with one another and with the car. The frequencies are transmitted by a small antenna within the middle of the key. This signal is encrypted to stop others from stealing or modifying the signal.
Keyfobs can be programmed in various ways based on the make and model of your vehicle. It is possible to do this yourself, however most modern vehicles require a dealer or professional locksmith to program a replacement or additional fob.
When you press a key fob's button it transmits an informational code to the car's receiver it is linked to. The receiver compares the information with the 'allowed signals' that are stored in the key fob, and then locks or opens the car's doors. If the information doesn't match an chirping sound is heard and the car isn't able to operate.
Once the car is linked with a specific fob, it will only receive signals from that specific device. This means that other fobs will not work with the vehicle even if they look the same. This protects the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
Most dealerships with newer cars will only work with vehicles that have original fobs or genuine replacements sold by the manufacturer. It is because the only place with the experience to design the replacement fob is the service department of the dealer. However, some fobs from the aftermarket typically for older models with less sophisticated systems -- can be programmed by consumers without the need for an authorized dealer.
