Transponder Chips
Transponder chips are likely be found in vehicles 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 the vehicle you own.
When it is activated by an electro-magnetic field, the chip emits a low-level signal. The signal is taken up by an antenna that is attached to the ignition barrel. This allows the car's computer system to determine if the transponder chip in the key is the correct one for the car you have.
This is what stops doing hot-wiring or altering the ignition system of the vehicle to turn it on. The chip in the car key verifies that the owner is the person who is the owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Transponder keys that are regular in shape like regular metal keys with an outer layer of plastic. The chip is inside the plastic part of the keys. There are several different cuts: a standard cut, Laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.
The circuit in the induction coil will emit a signal when the transponder is put into the ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the onboard car computer detects this signal as the right one, it will shut down the vehicle immobilizer and allow the engine to start.
If the car doesn't recognize the transponder as being the proper signal, it will not start the engine, and will alert you with flashing lights and siren. This is designed to discourage people from attempting to alter the vehicle, but it's not a 100% security measure. A determined and skilled thief can still get around this system with a specially designed device that intercepts the signal.

When you hit the button on a key fob, the microchip inside transmits an encoded code to the car's receiver that it is linked to. The receiver then compares the data with the 'allowed signals' that are stored on the key fob and then locks or opens the car's door. If the information isn't in line, a chirping sound is heard and the car isn't permitted to function.
After the car has been associated with a particular fob, it will only accept signals from that device. In turn, other fobs won't work with the vehicle, even though they look the same. This helps to protect the integrity of the car's computer system and to prevent the use of unauthorized key fobs to gain control over the vehicle.
Most newer car dealers will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. This is because the only place with the expertise to prepare a replacement fob is in the service department of the dealer. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems -- can be programmed by the consumer without the need for an authorized dealer.
