Transponder Chips
Transponder chips are likely to be found in cars manufactured within the past 20 years. This is a little plastic thing inside the head of your key that contains an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
When it is activated by an electro-magnetic field, the chip emits a low-frequency signal. The signal is then absorbed by a special antenna attached to the barrel of ignition. This allows the vehicle's computer system to determine if the transponder chip in the key is the correct one for your specific vehicle.
This is what stops doing hot-wiring or altering the ignition system of your vehicle to get it started. The chip in the key also proves that you are the legal owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Transponder keys appear like regular metal keys, but with a plastic cap. The chip is contained inside the plastic portion of the key and there are different kinds of cuts available on these keys: a standard cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal will be absorbed by the chip and cause it to transmit a signal back to the car. If the computer inside the car detects the signal as being correct it will turn off the car immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder as a valid signal, it won't start the engine and will alert you with flashing lights and siren. This feature is designed to discourage people from tampering with the vehicle. However it's not an unbreakable security measure. A skilled and determined thief could still bypass this system by using a specific device that blocks the signal.

Key Fobs

These extra features can make it difficult to find your car keys.
Key fobs use radio frequencies to communicate with each other and the car. These frequencies are transmitted via a small antenna that is located in the middle of the key. The transmission is encrypted, which helps keep others from stealing and re-transmitting the signal.
You can program a keyfob in a variety of ways depending on the make and model of your car. Some cars allow you to do it yourself. However, the majority of newer models require you to visit a professional locksmith or dealer to program a new key fob or additional one.
When you hit the button on a key fob it transmits an informational code to the car's receiver that it is paired with. The receiver compares this information to the signals that are allowed inside the fob, and either locks or opens the door. If the information isn't in line, a chirping sound is heard and the car isn't permitted to operate.
Once the car has been associated with a particular fob, it will only accept signals from that device. Other fobs won't work with the car, even if they appear like. This helps to protect the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.
Most dealerships with newer cars will only accept cars that have original fobs, or genuine replacements sold by the manufacturer. The reason for this is that the only place that has the expertise to prepare the replacement fob is the service department of the dealer. However, some aftermarket fobs typically for older models with less sophisticated systems -- can be programmed by consumers without the need of dealers.
