This is because the key has not yet been programmed into the car's system. This can be expensive. It is best to have two keys that work with your current car so you can program the replacement key whenever required. Keyprogrammers can recode a transponder chip on the new mechanical key or key fob. It is also able to copy data from an existing key to create duplicates. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They are equipped with diagnostic software, which allows them to communicate with a computer. They also have a bidirectional user interface for working with an immobilizer system.

Transponder Chips Transponder chips are likely to be found in vehicles manufactured within the last 20 years. This is a little piece of plastic on the back of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own. When key programer is activated by an electromagnetic field, the chip emits a low-level signal. The signal is then absorbed by the special antenna that is positioned around the barrel that controls your ignition in your car. The computer system of 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 key also proves that you are the legal owner of the vehicle. This helps to prevent the possibility of theft from your vehicle. Transponder keys look like normal keys but they have caps made of plastic. The chip is located inside the plastic portion of these keys. There are a variety of cuts such as a standard cut laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe. A circuit inside the induction coil will emit signals when the transponder is inserted into ignition barrel. The signal is taken up by the chip, which sends a signal to the vehicle. If the car's computer recognizes this signal as the right one, it will disable the immobilizer on the vehicle and allow the engine to begin. If the car isn't able to recognize the transponder as a valid signal, it won't start the engine and will alert you with flashing lights and a siren. This feature is designed to deter people from trying to alter the vehicle, but it isn't a foolproof security measure. A determined and skilled thief could still evade this system with a specially designed device that detects the signal. As you can see there are quite number of advantages to having transponder keys. This is something that all car owners should consider if they want to protect their investment and decrease the chance of theft. Key Fobs In addition to locking and unlocking doors, starting the car from a distance or making noises to aid in finding the car in a parking lot Key fobs today can also activate a heated steering wheel, or roll down all windows with just a single press. These extra features can make it difficult to find your car keys. Key fobs communicate with one other and the car using radio frequencies that are transmitted by an antenna in the center of the key. This communication is encrypted to prevent others from stealing or stealing the signal. There are several ways to program a key fob based on your vehicle's make and model. You may be able to do it yourself, however most modern automobiles require an expert locksmith or dealer to program a replacement or a second fob. When you press the button on your key fob, the microchip inside transmits an informational code to the car's radio that it is linked to. The receiver compares this information with the signals that are allowed on the fob and either opens or closes the door. If the information isn't in line an chirping sound is heard and the car isn't able to function. Once the car has been associated with a particular fob, it will only accept signals from the device. Other fobs won't work with the car, even if they appear identical. This protects the integrity of the vehicle's computer system and prevent unauthorized key fobs from gaining control of the vehicle. The majority of newer dealers will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security expertise which can only be obtained in the dealer service department. Some aftermarket fobs, usually ones for older models that have less sophisticated systems can be programmed without the need for a dealer.
