Transponder Chips
If your car was manufactured within the last 20 years, it is likely that it contains a transponder chip within of it. It's a small piece of plastic inside the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
When it is activated by an electromagnetic field, the chip emits a low-frequency signal. The signal is then absorbed by the special antenna that is attached to the barrel that controls your ignition in your car. This allows the car's computer system to verify that the transponder chip that is in the key is the correct one for your particular car.
This is the reason why from modifying or hot-wiring the ignition system of the vehicle to get it started. The chip inside the key confirms that the owner is the person who owns the vehicle. This can reduce car theft.
Transponder keys look like regular keys made of metal but have caps made of plastic. The chip is contained within the plastic portion of the keys. There are several different cuts: a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe) and a Ford Tibbe.
A circuit within the induction coil emits an electrical signal when the transponder is placed in the the ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the car's computer recognizes this signal as the right one, it will disable the vehicle immobilizer and allow the engine to begin.
If the vehicle does not recognize the transponder signal as being the right one, it will keep the engine from running and will notify you by flashing its lights and sounding a siren. This feature is designed to discourage people from trying to alter the vehicle, but it's not a 100% security measure. A skilled and skilled criminal could still bypass this system by using a specific device that blocks the signal.

Many of these extra features may appear convenient but they could make it difficult for you to keep the track of your car keys.
Key fobs communicate with one other and the car using radio frequencies that are transmitted through an antenna that is located in the center of the key. This communication is encrypted to block other key fobs from stealing or modifying the signal.
Keyfobs can be programmed in different ways based on the model and make of your vehicle. Some cars allow you to do it yourself. However, the majority of modern models require you to visit a professional locksmith or dealer to program a new key fob or an additional one.
When you press the button on a key fob the microchip transmits a signal to the receiver in the car with which it is linked. The receiver then compares this information with the 'allowed' signals stored in the fob and then either opens or locks the door. If the information doesn't match an chirping sound is heard and the car isn't able to operate.
Once the car is linked with a specific fob, it will only receive signals from that specific device. This means that other fobs won't be able to work with the vehicle even if they have the same appearance. This helps to protect the integrity of the car's computer system and prevent the use of unauthorized key fobs to gain control over the vehicle.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security expertise which can only be obtained in the dealer's service department. Some fobs from the aftermarket, especially those for older models with less advanced systems can be programmed without the need for a dealership.
