Transponder Chips
Transponder chips can be found in vehicles manufactured within the past 20 years. This is a little piece of plastic inside the head of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then amplified by the specific antenna that is fitted around the barrel that controls your ignition in your car. 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 your vehicle to start it. The chip in the key also verifies that you are the genuine owner of the vehicle. This will help reduce car theft.
Regular transponder keys are designed like regular metal keys with a plastic top. The chip itself is housed inside the plastic portion of the key and there are a few different kinds of cuts available on these keys: a standard cut laser cut (also known as a sidewinder key) or Ford Tibbe key.
The circuit in the induction coil will emit a signal when the transponder is placed in the the ignition barrel. The signal will then get taken up by the chip and cause it to send a signal back to the car. If the computer inside the car recognizes the signal as correct, it will disable vehicle immobilizer to allow the engine start.
If the car does not recognize the transponder signal as being the right one, it will stop the engine from running and will notify you by flashing its lights and sounding siren. This feature is designed to deter people from trying to tamper with the vehicle, however it isn't a foolproof security measure. A skilled and committed thief could still be able to get around this system employing a device designed to intercept the signal.

Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making chirping sounds to help find the car in a parking lot Key fobs today can also turn on the heated steering wheel or roll down all of the windows with just a single press. A lot of these additional features may seem convenient, but they can also make it difficult for you to keep track of your car keys.
Key fobs utilize radio frequencies to communicate with each other and the car. The frequencies are transmitted 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.
You can program a keyfob in various ways based on the model and brand of your car. You may be able to do it yourself, however most modern automobiles require a dealer or professional locksmith to program a replacement or a second fob.
When you press the button on a key fob the microchip sends a signal to the receiver inside the car with which it is paired. The receiver compares the information with the 'allowed signals' stored in the key fob and then locks or opens the car's door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't able to operate.
Once the car is paired with a specific fob, it will only accept signals from that device. In turn, other fobs won't be able to work with the vehicle even though they appear similar. This protects the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
The majority of newer dealers will only work on a car with original fobs or genuine replacements supplied by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security skills that is only available in the dealer service department. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems can be programmed by the consumer without the need of an authorized dealer.
