Transponder Chips
Transponder chips can be found in cars manufactured within the past 20 years. reprogram car key is a little piece of plastic in the head of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is taken up by an antenna attached to the barrel of ignition. The computer system in the vehicle is then able to verify that the transponder chip of the key is the correct one for your car.
This prevents the vehicle from being started by either hot-wiring or by manipulating. The chip in the key also proves that you are the legitimate owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.
Transponder keys appear like normal keys, but with caps made of plastic. The chip is located inside the plastic part of the keys. There are various cuts that are a standard cut, a Laser cut (also known as 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 sends out a signal. The signal will then get absorbed by the chip, causing it to transmit a signal to the car. If the computer onboard the car recognizes the signal as being correct, it will disable vehicle immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder signal as being the proper one, it will stop the engine from running and will notify you by flashing its lights and sounding an alarm.

There are many ways to program a key fob depending on your vehicle's make and model. It is possible to do this yourself, but most newer automobiles require a locksmith shop or a professional to program a replacement or a second fob.

Once the car is linked with a specific fob, it will only accept signals from that specific device. Other fobs won't work with the car, even if they appear similar. This protects the integrity of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control of it.
The majority of newer dealers will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer. This is because preparing a replacement fob requires technological and security skills that can only be found in the dealer service department. Some fobs from the aftermarket, especially those from older models that have less advanced systems can be programmed without the need for a dealer.
