Keyprogrammers can recode the transponder chip on the new mechanical key or key fob. It is also able to copy data from an existing key to make duplicates.

Transponder Chips Transponder chips are likely to be found in cars that were manufactured in the last 20 years. This is the little plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own. The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is then absorbed by the special antenna that is fitted around the ignition barrel of your vehicle. This allows the vehicle's computer system to confirm that the transponder chip in the key is the correct one for the car you have. This is what stops hot-wiring or tampering with the vehicle's ignition system to get it started. The chip inside the key verifies that the owner is the one who owns the vehicle. This will help reduce car theft. Transponder keys resemble regular keys made of metal, but with caps made of plastic. The chip itself is housed in the plastic portion of the key, and there are different types of cuts on the keys: a cut laser cut (also called a sidewinder), or a Ford Tibbe key. When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the car's computer detects this signal as the correct one, it will disable the immobilizer on the vehicle and allow the engine to start. If the vehicle doesn't recognize the transponder signal as being the proper one, it will keep the engine from running and will alert you by flashing its lights and sounding a siren. This function is designed to discourage people from tampering with the vehicle. However it's not an unbreakable security measure. A skilled and determined thief can still get around this system using a special device that intercepts the signal. It is evident that the transponder is a good option. This is something that all vehicle owners should consider if they want to safeguard their investment and reduce the risk of theft. Key Fobs In addition to locking and unlocking doors, launching the car from a distance or making sound chirps to help locate a car in a parking space Key fobs today can also turn on a heated steering wheel, or roll down all of the windows with a single button press. A lot of these features may seem convenient but they could make it difficult for you to keep the keys to your car. Key fobs communicate with one with the car via radio frequencies that are transmitted by a small antenna located in the center of the key. The transmission is encrypted, which helps stop others from stealing and re-transmitting the signal. Keyfobs can be programmed in different ways based on the model and brand of your vehicle. It is possible to do this 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 a key fob, the microchip sends an indication to the receiver in the car with which it is paired. The receiver compares the information with the 'allowed signals' that are stored on the key fob and then opens or locks the car's door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to operate. After the car has been connected to a specific fob, it will only accept signals from the device. This means that other fobs won't work with the vehicle even if they look the same. This protects the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle. Most newer car dealerships will only deal with cars that have original fobs, or genuine replacements sold 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. However, some fobs from the aftermarket — usually those for older models that have less sophisticated systems can be programmed by customers without the need of an authorized dealer.
