This is because the key has not yet been programmed into the vehicle's system. This could be costly. This is why it's a good idea to have two keys working for a modern car and to have the replacement key programmed if necessary.
A keyprogrammer can recode a transponder chip on an entirely 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 come with diagnostic software that allows them to communicate with a computer.

Transponder Chips
If your car is made within the past 20 years, it is likely that it has a transponder chip inside of it. This is the little plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to your car.
When activated by an electro-magnetic field the chip emits a low level signal. The signal is then absorbed by the special antenna that is positioned around the ignition barrel of your vehicle. The computer system in the vehicle will then confirm that the transponder chip of the key is the correct one for your car.
This stops the vehicle from being started by either hot-wiring or by altering the key. The chip inside the key verifies that the owner is the person who owns the vehicle. This can help to reduce car theft.
Transponder keys that are regular in shape like regular keys and have a plastic top. The chip is contained within the plastic portion of the keys. There are various cuts: a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe) and Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out a signal. The signal will then get received by the chip, causing it to transmit a signal back to the car. If the computer inside the car is able to recognize the signal as valid it will turn off the car immobilizer so that the engine can start.
If the car doesn't recognize the transponder as the correct signal, it will not start the engine and will alert you with flashing lights and siren. This feature is intended to discourage people from attempting to alter the vehicle, but it is not a foolproof security measure. A skilled and determined criminal could still be able to escape this security system by employing a device designed to take over the signal.
You can see that a transponder is a great option. This is something that all vehicle owners should consider if they want to safeguard their investment and minimize the chance of theft.
Key Fobs
Key fobs today can do more than just lock and unlock doors. They can also start the vehicle remotely, make chirping noises to aid in finding a car, or switch on the heated steering wheel. These extra features can make it difficult to locate your car keys.
Key fobs utilize radio frequencies to connect with one another and the car. These frequencies are sent through a small antenna located within the middle of the key. This communication is encrypted to prevent others from stealing or modifying the signal.
You can program a keyfob in various ways based on the model and make of your car. Certain cars let you do this yourself. However, most newer models require you to visit a professional locksmith or dealer in order to program a new key fob, or an alternative one.
When you press a key fob's button it transmits a code to the car's receiver it is paired with. The receiver then compares the data with the permitted signals stored in the key fob, and then it opens or closes the car's doors. If the information isn't in line, a chirping sound is heard and the car isn't allowed to function.
When a car is connected with a particular fob, it will only receive signals from that specific device. Other fobs won't work with the car, even if they appear like. This ensures the security of the computer system in the car and blocks unauthorized key fobs gaining control of it.
Most newer car dealerships will only deal with cars with original fobs or genuine replacements supplied by the manufacturer. It is because the only place with the expertise to prepare a replacement fob is in the service department of the dealer. However, some fobs from the aftermarket typically for older models with less sophisticated systems can be programmed by the consumer without the need of a dealership.
