Transponder Chips
Transponder chips are likely be found in vehicles manufactured within the past 20 years. It's the tiny piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your vehicle.
When activated by an electro-magnetic field the chip emits a low level signal. The signal is then received by a specific antenna attached to the ignition barrel. This allows the car's computer system to confirm that the transponder chip inside the key is the correct one for the car you have.
This is the reason why doing hot-wiring or altering the ignition system of your vehicle to start it. The chip in the key also verifies that you are the genuine owner of the vehicle. This helps to prevent car theft.
Transponder keys look like regular metal keys but they have caps made of plastic. The chip is housed in the plastic portion of the key and there are different cuts that can be found on the keys: a standard cut laser cut (also called a sidewinder) or Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out a signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer onboard the car detects the signal as valid it will turn off the car immobilizer so that the engine can start.
If the car does not recognize the transponder signal as being the right one, it will keep the engine from starting and will alert you by flashing its lights and sounding a siren. This system is designed to deter those who would attempt to alter the vehicle. However it's not an absolute security measure. A skilled and committed thief could still be able to get around this system using a device that can intercept the signal.
You can see that the transponder is an excellent option. Every car owner should take this into consideration if they wish to protect their investment and reduce theft risk.
Key Fobs

These additional features can make it difficult to locate your car keys.
Key fobs are able to communicate with each other and the car using radio frequencies that are transmitted through an antenna in the center of the key. The communication is encrypted, which helps to stop others from stealing and replicating the signal.
There are many ways to program a key fob based on your vehicle's make and model. 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 a second fob.
When you press the button on a key fob, the microchip transmits signals to the receiver in the car with which it is linked. The receiver then compares the data with the permitted signals stored in the key fob, and then it opens or closes the car's door. If the data does not match the fob's information, the car won't be allowed to drive.
Once the car is linked with a particular fob, it will only accept signals from the device that is associated with it. Other fobs will not work with the car, despite the fact that they appear like. This ensures the security of the computer system in the car and blocks the use of unauthorized key fobs to gain control over it.
Most newer car dealerships will only deal with cars with original fobs or genuine replacements sold by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security expertise that is only available in the dealer's service department. However, some aftermarket fobs typically for older models that have less sophisticated systems -- can be programmed by consumers without the need of a dealership.
