This is because the key hasn't yet been programmed into the car's system. This can be expensive. car key programming is why it's a great idea to always have two working keys for a modern automobile and have the replacement key programmed when needed. Keyprogrammers are devices which can reprogram the transponder chip in an entirely new mechanical or key fob key. It is also able to copy data from an existing key to make duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software, which allows them to communicate with computers.

Transponder Chips If your car is made in the past 20 years, it is likely that it contains a transponder chip within of it. It's a small plastic piece in the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle. The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is received by a specific antenna attached to the ignition barrel. This allows the car's computer system to verify that the transponder chip in the key is the right one for the car you have. This is what stops from modifying or hot-wiring the ignition system of the vehicle to get it started. The chip in the key also verifies that you are the genuine owner of the vehicle. This will help reduce car theft. Transponder keys that are regular in shape like regular keys, but with an outer layer of plastic. The chip is housed in the plastic portion of the key, and there are a few different kinds of cuts available on these keys: a cut, a laser cut (also called a sidewinder), or a Ford Tibbe key. When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out a signal. The signal will be absorbed by the chip, causing it to transmit a signal back to the car. If the computer on the car detects this signal as the correct one, it will turn off the vehicle's immobilizer and allow the engine to begin. If the car does not recognize the transponder signal as the right one, it will keep the engine from starting and will notify you by flashing its lights and sounding an alarm. This feature is designed to discourage individuals from tampering with the vehicle. However it isn't an absolute security measure. A determined and skilled thief could still bypass this system by using a specific device that detects the signal. As you can see, there are quite a number of benefits to having transponder keys. Every car owner should consider this when they want to safeguard their investment and minimize the risk of theft. Key Fobs In addition to locking and unlocking doors, starting 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 roll down all of the windows with a single button click. A lot of these additional features may appear convenient but they could make it difficult for you to keep the track of your car keys. Key fobs use radio frequencies to communicate with one another and with the car. These frequencies are transmitted through a small antenna located within the middle of the key. This communication is encrypted, which helps prevent others from intercepting and replicating the signal. You can program a keyfob in different ways based on the model and brand of your car. automotive key programming may be able to do it yourself, but the majority of newer vehicles require a dealer or professional locksmith to program a replacement or a second fob. When you press the button on a key fob the microchip sends a signal to the receiver in the car with which it is linked. The receiver compared the information with the 'allowed signals' that are stored in the key fob and then it opens or closes the car's doors. If the data does not match, the car will not be allowed to drive. After the car has been paired with a specific fob, it will only accept signals from the device. Other fobs won't work with the car, even if they look similar. This ensures the security of the computer system in the vehicle and stops unauthorised key fobs from taking control over it. The majority of newer dealerships will only deal with cars that have original fobs, or genuine replacements offered by the manufacturer. It is because the only place with the experience to design the replacement fob is a dealer's service department. However, some fobs from the aftermarket typically for older models with less sophisticated systems can be programmed by customers without the need of an authorized dealer.
