Transponder Chips
If your car was manufactured in the last 20 years, then it has a transponder chip inside of it. It's the tiny piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
When it is activated by an electromagnetic field the chip emits a low-level signal. This signal is then absorbed by a special antenna attached to the barrel of ignition. The computer system of the vehicle can then verify that the transponder chip of the key is the correct one for your car.
This stops the vehicle from being started by either hot-wiring or by manipulating. The chip in the car key confirms that the owner is the one who is the owner of the vehicle. This helps to prevent car theft.
Regular transponder keys are designed like regular metal keys with a plastic top. The chip is located inside the plastic part of the keys. There are a variety of cuts that are a standard cut, Laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.
A circuit within the induction coil will emit signals when the transponder is put into an ignition barrel. The signal is received by the chip which sends a signal to the vehicle. If the car's computer recognizes this signal as the right one, it will turn off the vehicle immobilizer and allow the engine to begin.
If the car doesn't recognize the transponder as the correct signal, it won't start the engine, and will warn you with flashing lights and an alarm. This function is designed to discourage individuals from tampering with the vehicle. However it's not a foolproof measure of security. A determined and skilled thief could still bypass this system using a special device that blocks the signal.
You can see that the transponder is an excellent option. Every car owner should take this into consideration when they want to safeguard their investment and reduce theft risk.
Key Fobs

These additional features could make it difficult to find your car keys.
Key fobs make use of radio frequencies to communicate with one another and the car. These frequencies are sent by a small antenna within the middle of the key. This communication is encrypted, which helps keep others from stealing and re-transmitting the signal.
Keyfobs can be programmed car keys in different ways based on the model and make of your car. It is possible to do this yourself, but the majority of newer cars require that you visit a dealer or professional locksmith to program a replacement or additional fob.
When you hit the button on a key fob the microchip inside sends a code to the car's radio that it is linked to. The receiver then compares the data with the 'allowed signals' stored in the key fob and then locks or opens the car's door. If the data doesn't match, a chirping sound is heard and the car isn't allowed to operate.
Once the car is associated with a particular fob, it only accepts signals from that device. Other fobs won't work with the car, despite the fact that they appear like. This helps to protect the integrity of the vehicle's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.
Most newer car dealerships will only work with cars with original fobs or genuine replacements supplied by the manufacturer. This is because the only place that has the knowledge to create the replacement fob is a dealer's service department. However, some fobs from the aftermarket typically for older models with less sophisticated systems -- can be programmed by the consumer without the need of dealers.
