Other kinds of programming car key s are much easier and can be performed by anyone who is able to. They are accomplished using the onboard diagnostic port, which can be accessed with a special tool for key-fob programming.

Transponder Chips
Transponder chips are likely to be found in cars that were manufactured within the last 20 years. It's a small plastic thing inside the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
When it is activated by an electromagnetic field the chip emits a low-frequency signal. The signal is then absorbed by a special antenna attached to the barrel of ignition. The computer system in the vehicle can then verify that the key's transponder chip is the correct one for your vehicle.
This stops the vehicle from being started by either hot-wiring or by manipulating. The chip in the car key ensures that the owner is the one who is the owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys that are regular in shape like regular keys and have a plastic top. The chip is contained within the plastic portion of these keys. There are various cuts such as a standard cut a Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal will then get taken up by the chip and cause it to transmit a signal to the car. If the computer in the car is able to recognize the signal as valid, it will disable vehicle immobilizer, allowing the engine to start.
If the car doesn't recognize the transponder as a valid signal, it will not start the engine, and will warn you with flashing lights and an alarm. This is designed to deter people from trying to alter the vehicle, however it isn't a foolproof security measure. A skilled and skilled criminal could still evade this system by using a specific device that detects the signal.
You can see that the transponder is an excellent option. This is something that all car owners should consider if they are looking to safeguard their investment and decrease the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making chirping sounds to help find a car in a parking lot keys of today can also turn on the heated steering wheel or open all windows with just a single press. These extra features can make it difficult to find your car keys.
Key fobs communicate with each other and with the car through radio frequencies that are transmitted via a small antenna located in the center of the key. This signal is encrypted to prevent others from stealing or modifying the signal.
There are a few different ways to program a key fob, based on the model and make. Some cars allow you to do this yourself. However, the majority of newer models require you to visit an expert locksmith or dealer to program a replacement key fob or additional one.
When you press the button on a key fob the microchip sends signals to the receiver inside the vehicle with which it is paired. The receiver compares this information to the 'allowed' signals stored in the fob and then either opens or closes the door. If the information isn't in line an chirping sound is heard and the car isn't permitted to operate.
When a car is connected with a specific fob, it will only receive signals from that specific device. In turn, other fobs won't be able to work with the vehicle even though they have the same appearance. This helps to protect 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 cars with original fobs or genuine replacements that are offered by the manufacturer. It is because the only place with the knowledge to create an appropriate replacement fob is a dealer's service department. 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 a dealership.
