This is because the key hasn't yet been programmed into the vehicle's system. This can be expensive.

It is also able to clone data of an existing key which allows duplicate keys to be created. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They have diagnostic software that allows them to communicate with the computer, and they also have an interface that works bidirectionally with the immobilizer system.
There are a myriad of types of keyprogrammers available on the market. They come in all sizes, shapes, and colors. Some are inexpensive and others can cost thousands of dollar.

Transponder Chips
If your car was manufactured in the past 20 years, chances are it has a transponder chip inside of it. This is a little piece of plastic on the back of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
When activated by an electro-magnetic field, the chip emits a low-frequency signal. This signal then gets amplified by the specific antenna that is fitted around the ignition barrel of your vehicle. The computer system in the vehicle is then able to verify that the transponder chip of the key is the right one for your vehicle.
This is what stops from modifying or hot-wiring the ignition system of your vehicle to get it started. The chip in the key also proves that you are the genuine owner of the vehicle. reprogram car key helps to prevent car theft.
Transponder keys resemble regular keys made of metal but they have a plastic cap. The chip is inside the plastic part of the keys. There are several different cuts that are a standard cut, a Laser cut (also known as a sidewinder or Ford Tibbe) and a Ford Tibbe.
A circuit inside the induction coil emits an electrical signal when the transponder is put into the ignition barrel. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer on the car recognizes this signal as being the right one, it will shut down the vehicle's immobilizer and allow the engine to start.
If the car does not recognize the transponder signal as being the proper one, it will stop the engine from running and will alert you by flashing its lights and sounding a siren. This feature is designed to discourage people from trying to tamper with the vehicle, but it's not a 100% security measure. A skilled and determined thief could still evade this system using a special device that detects the signal.
As you can see there are quite few advantages to getting transponder keys. This is something that all car owners should consider if want to protect their investment and decrease the risk of theft.
Key Fobs

Many of these extra features may appear convenient however they could make it harder for you to keep the track of your car keys.
Key fobs are able to communicate with each other and with the car through radio frequencies that are transmitted by a small antenna located in the middle of the key. This signal is encrypted to block other key fobs from stealing or modifying the signal.
There are many ways to program a key fob depending on the model and make. You may be able to do it yourself, however most modern vehicles require a locksmith shop or a professional to program a replacement or additional fob.
When you press the button on your key fob it transmits an encoded code to the car's receiver it is linked to. The receiver then compares the data with the permitted signals stored in the key fob and then opens or locks the car's door. If the information does not match, the car will not be allowed to drive.
Once the car has been paired with a specific fob, it will only accept signals from the device. In turn, other fobs will not work with the vehicle even though they look the same. This helps to protect the integrity of the vehicle's computer system and prevent unauthorised key fobs from taking control over the vehicle.
Most newer car dealerships will only deal with cars with original fobs, or genuine replacements sold by the manufacturer. The reason for this is that the only place that has the expertise to prepare the replacement fob is a dealer's service department. Some aftermarket fobs, usually ones for older models that have less sophisticated systems can be programmed with out the need for a dealer.
