The reason is because the new key hasn't been programmed to the automobile's system – and this can be quite expensive. This is why it's a great idea to have two working keys for a modern automobile and to have the replacement key programmed if needed. Keyprogrammers are devices that can recode the transponder chip on an entirely new key fob or mechanical key. It can also clone the information from an existing key, allowing duplicates to be created. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that enables them to communicate with the computer, and they also have a bidirectional interface for working with the immobilizer system.

Transponder Chips If your car was built in the past 20 years, it is likely that it has a transponder inside of it. It's the tiny plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own. When it is activated by an electromagnetic field the chip emits a low-level signal. This signal then gets taken up by the antenna that is fitted around the ignition barrel of your car. The computer system in the vehicle can then verify that the key's transponder chip is the right one for your vehicle. This prevents the vehicle from being started by hot-wiring or altering the key. The chip inside the car key ensures that the owner is the person who owns the vehicle. This will help reduce car theft. Regular transponder keys are shaped like regular keys and have a plastic top. The chip is located inside 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 a Ford Tibbe. A circuit inside the induction coil will emit a signal when the transponder is inserted into ignition barrel. The signal will then get absorbed by the chip, causing it to send a signal back to the car. If the computer inside the car detects the signal as valid, it will disable vehicle immobilizer, allowing the engine to start. If the vehicle does not recognize the transponder signal as the proper one, it will keep the engine from running and will notify you by flashing its lights and sounding a siren. This system is designed to deter people from tampering with the vehicle. However it isn't an absolute security measure. A skilled and determined thief can still get around this system with a specially designed device that intercepts the signal. As you can see, there are quite a few advantages to getting a transponder key. Every car owner should take this into consideration if they wish to protect their investment and minimize the risk of theft. Key Fobs In addition to locking and unlocking doors, starting the car remotely or making noises to aid in finding a car in a parking lot Key fobs today can also turn on the heated steering wheel or roll down all windows with just a single press. Many of these extra features may seem convenient, but they can also make it more difficult to keep the track of your car keys. Key fobs utilize radio frequencies to communicate with one another and with the car. These frequencies are sent through a small antenna located in the middle of the key. This communication is encrypted to stop others from stealing or stealing the signal. You can program a keyfob in different ways based on the model and brand of your vehicle. It is possible to do this yourself, however most modern automobiles require a locksmith shop or a professional to program a replacement or an additional fob. When you press the button on a key fob, the microchip sends a signal to the receiver in the vehicle with which it is paired. The receiver compared the information with the 'allowed signals' that are stored in the key fob, and then opens or locks the car door. If the information isn't in line an chirping sound is heard and the car isn't permitted to operate. After the car has been connected to a specific fob, it will only accept signals from that device. In turn, other fobs will not work with the vehicle even though they have the same appearance. This is to safeguard the integrity of the car's computer system, and also to stop unauthorised key fobs from taking control of the vehicle. Most newer car dealers will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security knowledge which can only be obtained in the dealer's service department. Certain aftermarket fobs, typically those for older models that have less sophisticated systems can be programmed with out the need for a dealership.
