The reason is because the new key has not been programmed to the car's system - and this can be quite expensive. This is why it's a great idea to have two keys working for modern vehicles and have the replacement key programmed when necessary. A keyprogrammer can reprogram the transponder chip of the new mechanical key or key fob. It is also able to copy information from an existing key in order to create duplicates. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that allows them to communicate with a computer. They also have a bidirectional interface for working with an immobilizer system.

Transponder Chips If your car was manufactured within the past 20 years, chances are it contains a transponder chip within of it. It's the tiny plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your vehicle. When it is activated by an electromagnetic field the chip emits a low level signal. The signal is then absorbed by a special antenna that is attached to the ignition barrel. https://www.g28carkeys.co.uk/car-key-programming-near-me/ of the vehicle is then able to verify that the key's transponder chip is the correct one for your vehicle. This is what prevents doing hot-wiring or altering the ignition system of your 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 resemble regular keys made of metal, but with caps made of plastic. The chip is contained within the plastic part of these keys. There are a variety of cuts that are a standard cut, Laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe. A circuit inside the induction coil emits a signal when the transponder is put into an ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the computer inside the car recognizes the signal as valid it will turn off the vehicle immobilizer, allowing the engine to start. If the vehicle doesn't recognize the transponder signal as the proper one, it will prevent the engine from starting and will notify you by flashing its lights and sounding a siren. This is designed to discourage people from attempting to tamper with the vehicle, however it isn't a foolproof security measure. A skilled and determined thief could still bypass this system using a special device that blocks the signal. As you can see there are quite a number of advantages to having a transponder key. All car owners must take this into consideration if they wish to protect their investment and reduce theft risk. Key Fobs In addition to locking and unlocking doors, launching the car remotely, or making chirping sounds to help find the car in a parking lot Key fobs today can also turn on the heated steering wheel or roll down all of the windows with a single press. These extra features could make it difficult to locate your car keys. Key fobs are able to communicate with each other and with the car through radio frequencies that are transmitted through an antenna that is located in the middle of the key. The transmission is encrypted, which helps stop others from stealing and replicating the signal. There are several ways to program a key fob, based on your vehicle's make and model. Certain cars let you do this by yourself. However, the majority of modern models require you to visit a professional locksmith or dealer in order to program a new key fob or an additional one. When you hit the button on a key fob, the microchip inside transmits a code to the car's receiver it is paired with. The receiver compared the information with the permitted signals stored on the key fob and then locks or opens the car's doors. If the information doesn't match the signals, the car will not be allowed to drive. When a car is connected with a specific fob, it will only receive signals from that device. In turn, other fobs won't work with the vehicle even though they appear similar. This safeguards the integrity of the computer system that runs the car and blocks the use of unauthorized key fobs to gain control of it. Most newer car dealerships will only accept cars with original fobs, or genuine replacements supplied by the manufacturer. This is because the only place that has the expertise to prepare the replacement fob is the service department of the dealer. Some aftermarket fobs, usually those from older models that have less sophisticated systems can be programmed with out the need for a dealer.
