This is because the key has not yet been programmed into the car's system. This can be expensive. It is recommended to have two keys that are compatible with your current car so you can program the replacement key whenever needed.
A keyprogrammer can recode the transponder chip of a new mechanical key or key fob. It can also clone the data from an existing key and allow duplicate keys to be created. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software, which allows them to communicate with a computer. They also feature a bidirectional user interface that works with an immobilizer system.

Transponder Chips
If your car is made within the past 20 years, it is likely that it contains a transponder chip within of it. It's the small piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for your vehicle.
When it is activated by an electromagnetic field, the chip emits a low-level signal. This signal is then taken up by an antenna that is attached to the barrel of ignition. The computer system in the vehicle is then able to verify that the key's transponder chip is the right one for your car.
This prevents the vehicle from being started by hot-wiring, or by manipulating. The chip in the key also proves that you are the genuine owner of the vehicle. This can reduce car theft.
Regular transponder keys are shaped like regular keys, but with a plastic top. The chip is housed within the plastic part of the key and there are a few different types of cuts on these keys: a standard cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key.
The circuit in the induction coil emits a signal when the transponder is inserted into the ignition barrel. The signal will be received by the chip, causing it to send a signal back to the car. If the computer on the car recognizes this signal as the right one, it will turn off the vehicle's immobilizer and allow the engine to begin.
If the car does not recognize the transponder signal as the correct one, it will prevent the engine from starting and will alert you by flashing its lights and sounding an alarm. This is designed to deter people from trying to tamper with the vehicle, but it is not a foolproof security measure. A skilled and determined thief may still be able to bypass this system by employing a device designed to detect the signal.
As you can see, there are quite a number of benefits to having a transponder key. This is something that all vehicle owners should consider if they want to protect their investment and decrease the risk of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start your vehicle remotely, emit chirping sounds to help locate the car or turn on the heated steering wheel. These extra features can make it difficult to find your car keys.
Key fobs use radio frequencies to communicate with each other and with the car. The frequencies are transmitted by a small antenna in the middle of the key. The communication is encrypted, which helps to prevent others from intercepting and retransmitting the signal.
Keyfobs can be programmed in a variety of ways depending on the model and brand of your vehicle. You can sometimes do this yourself, however most modern vehicles require a locksmith shop or a professional to program a replacement or a second fob.
When you press a key fob's button the microchip inside sends a code to the car's receiver that it is linked to. The receiver compares the information with the 'allowed signals' that are stored in the key fob, and then it opens or closes the car door. If the information does not match the signals, the car will not be allowed to run.
After the car has been connected to a specific fob, it can only receive signals from the device. As a result, other fobs will not work with the vehicle even though they look the same. This safeguards the integrity of the computer system of the car and prevents the use of unauthorized key fobs to gain control of it.
Most newer car dealerships will only work with vehicles that have original fobs, or genuine replacements offered by the manufacturer. This is because the process of creating a replacement fob requires technological and security skills that is only available in the dealer's service department. However, some aftermarket fobs -- usually those for older models with less sophisticated systems -- can be programmed by customers without the need for dealers.
