This is because the key could not work properly, or it will not start the car at all. The reason for this is that the new key hasn't been programmed into the vehicle's system, and this could be quite costly. It is recommended to have two keys that work with your current car so you can program the replacement key when needed.
A keyprogrammer is a device which can reprogram the transponder chip in a new key fob or mechanical 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 come with diagnostic software that enables them to communicate with the computer and also provide an interface that works bidirectionally with the immobilizer system.
There are many different types of keyprogrammers that are available on the market. They are available in a variety of sizes, shapes, and colors.

Transponder Chips
If your car is made within the last 20 years, then it has a transponder 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 it is activated by an electro-magnetic field, the chip emits a low level signal. The signal is absorbed by a special antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to confirm that the transponder chip in the key is the correct one for your specific vehicle.
This stops the vehicle from starting by hot-wiring, or by altering the key. The chip inside the key confirms that the owner is the person who owns the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular metal keys with a plastic top. The chip is contained within the plastic portion of these keys. There are various cuts that are a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer inside the car is able to recognize the signal as correct it will turn off the car immobilizer, allowing the engine to start.
If the vehicle doesn't recognize the transponder signal as the proper one, it will stop the engine from running and will notify you by flashing its lights and sounding an alarm. This system is designed to deter those who would attempt to alter the vehicle. However it isn't an absolute security measure. A determined and skilled thief could still evade this system using a special device that detects the signal.
As you can see there are quite number of benefits to having a transponder key. This is something that all car owners should consider if want to protect their investment and minimize the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making chirping sounds to help find the car in a parking space keys of today can also activate a heated steering wheel, or open all windows with a single click. A lot of these features may appear convenient but they could make it harder for you to keep track of your car keys.
Key fobs make use of radio frequencies to communicate with one another and with the car. These frequencies are sent via a small antenna that is located inside the middle of the key. This communication is encrypted, which helps to keep others from stealing and re-transmitting the signal.
Keyfobs can be programmed in various ways based on the model and brand of your vehicle. Some cars allow you to do it yourself. However, the majority of modern models require you to visit a professional locksmith or dealer to program a replacement key fob or an additional one.
When you press the button on your key fob it transmits an informational code to the car's receiver it is linked to. The receiver compares this information to the signals that are allowed inside the fob, and either opens or locks the door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't able to operate.
Once the car is linked with a particular fob, it will only accept signals from the device that is associated with it. As a result, other fobs will not work with the vehicle even if they look the same. This protects the integrity of the car's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.
The majority of newer dealerships will only work with cars with original fobs or genuine replacements sold by the manufacturer. It is because the only place that has the experience to design the replacement fob is the service department of a dealer. Some aftermarket fobs, usually ones for older models with less advanced systems, can be programmed without the need for a dealer.
