Transponder Chips
If your car was built within the past 20 years, chances are it contains a transponder chip within of it. This is a little piece of plastic in the head of your key which contains a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
When activated by an electro-magnetic field the chip emits a low-frequency signal. This signal is then taken up by the antenna that is attached to the ignition barrel of your vehicle. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the correct one for your car.
This is what stops from modifying or hot-wiring the ignition system of the vehicle to get it started. The chip in the car key confirms that the owner is the person who is the owner of the vehicle. This can help to reduce car theft.
Regular transponder keys are shaped like regular keys and have a plastic top. The chip is inside the plastic part of these keys. There are various cuts such as a standard cut a Laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.
A circuit inside the induction coil will emit signals when the transponder is inserted into ignition barrel. The signal will be received by the chip, causing it to send a signal back to the car. If the computer in the car is able to recognize the signal as valid it will turn off the vehicle immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder as the correct signal, it will not start the engine and warn you with flashing lights and siren. This function is designed to discourage individuals from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and committed thief may still be able to escape this security system by using a special device to detect the signal.

Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making sound chirps to help locate the car in a parking space, today's key fobs can also switch on a heated steering wheel or roll down all of the windows with a single press. These extra features could make it difficult to locate your car keys.
Key fobs make use of radio frequencies to connect with one another and the car. The frequencies are transmitted via a small antenna that is located in the middle of the key. This communication is encrypted, which helps stop others from stealing and replicating the signal.
You can program a keyfob in different ways based on the model and brand of your vehicle. Certain cars let you do this by yourself. However, most newer models require you to visit an expert locksmith or dealer in order to program a new key fob, or an alternative one.
When you press the button on a key fob, the microchip transmits a signal to the receiver in the car that it is paired. The receiver compares this information to the 'allowed' signals stored in the fob and then either locks or opens the door. If the data does not match, the car will not be allowed to operate.
Once the car is linked with a specific fob, it will only receive signals from that specific device. Other fobs will not work with the car, even though they look like. This ensures the security of the computer system that runs the car and prevents unauthorized key fobs gaining control of it.
Most dealerships with newer cars will only work with cars that have original fobs or genuine replacements offered by the manufacturer. It is because the only place that has the expertise to prepare a replacement fob is in the service department of a dealer. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems can be programmed by consumers without the need for dealers.
