They come with diagnostic software that enables them to communicate with the computer and also provide bidirectional interfaces to work with the immobilizer system.

Transponder Chips
If your car was manufactured within the past 20 years, chances are it has a transponder inside of it. This is a little plastic thing on the back of your key that contains an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. The signal is then absorbed by the special antenna that is attached to the ignition barrel of your vehicle. The computer system of the vehicle will then confirm that the transponder chip of the key is the right one for your car.
This stops the vehicle from being started by hot-wiring, or by tampering. The chip inside the car key confirms that the owner is the person who is the owner of the vehicle. This can reduce car theft.
Transponder keys resemble regular metal keys but they have a plastic cap. The chip is inside the plastic part of these keys. There are a variety of cuts that are a standard cut and program car Key (Linkagogo.trade), laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil sends out the signal. The signal will then get received by the chip, causing it to send a signal back to the reprogram car keys. If the computer in the car detects the signal as correct, it will disable vehicle immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder as a valid signal, it won't start the engine and will notify you via flashing lights and siren. This feature is designed to discourage individuals from tampering with the vehicle. However it isn't an unbreakable security measure. A determined and skilled thief could still evade this system using a special device that intercepts the signal.
You can see that the transponder is a good option. All car owners should consider this if they wish to protect their investment and decrease the chance of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also turn on the car from a distance, make chirping sounds to aid in finding the car, or switch on the heated steering wheel. These extra features can make it difficult to find your car key reprogrammed keys.
Key fobs make use of radio frequencies to communicate with one another and with the car. The frequencies are transmitted by a small antenna in the middle of the key. This signal is encrypted to stop others from stealing or modifying the signal.
You can program a keyfob in a variety of ways depending on the model and make of your vehicle. You may be able to do it yourself, however most modern vehicles require a dealer or professional locksmith to program a replacement or an additional fob.
When you press the button on your key fob the microchip inside sends an encoded code to the car's radio that it is linked to. The receiver then compares the data with the permitted signals stored in the key fob, and then it opens or closes the car door. If the information does not match, the car will not be allowed 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 work with the vehicle, even though they look the same. This protects the integrity of the car's computer system and prevent unauthorized key fobs from gaining control of the vehicle.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements offered by the manufacturer. This is because the only place that has the knowledge to create the replacement fob is the service department of the dealer. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems can be programmed by customers without the need of an authorized dealer.
