This is because the key hasn't yet been programmed into the vehicle's system. This can be expensive. This is why it's a good idea to always have two keys that work for a modern automobile and to have the replacement key programmed if needed.
Keyprogrammers are devices that recodes the transponder chip on the form of a new mechanical or key fob key. It also can clone the data of an existing key to make duplicates. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that enables them to communicate with computers, and they also have bidirectional interfaces to work with the immobilizer system.

Transponder Chips
If your car was built within the past 20 years, then it has a transponder inside of it. This is a little plastic piece inside the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.
When activated by an electro-magnetic field the chip emits a low-level signal. The signal is received by a specific antenna attached to the ignition barrel. The computer system of the vehicle is then able to verify that the transponder chip of the key is the correct one for your car.
This prevents the vehicle from starting by hot-wiring, or by manipulating. The chip in the car key verifies that the owner is the person who is the owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Regular transponder keys are designed like regular keys and have an outer layer of plastic. The chip itself is housed in the plastic portion of the key and there are different cuts that can be found on the keys: a cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.
A circuit inside the induction coil will emit an electrical signal when the transponder is put into ignition barrel. The signal will be taken up by the chip and cause it to send a signal back to the car. If the computer onboard the car detects the signal as correct, it will disable vehicle immobilizer so that the engine can start.
If the vehicle does not recognize the transponder signal as the proper one, it will stop the engine from starting and will alert you by flashing its lights and sounding siren. This system is designed to deter people from tampering with the vehicle. However, it is not an absolute security measure. A determined and skilled thief can still get around this system by using a specific device that detects the signal.
It is evident that the transponder is an excellent option. This is something that all vehicle owners should think about if they want to protect their investment and decrease the risk of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also start your car remotely, make chirping noises to help locate the car or switch on the heated steering wheel. These extra features can make it difficult for you to find your car keys.
Key fobs communicate with each with the car via radio frequencies that are transmitted by a small antenna located in the middle of the key. This communication is encrypted to block other key fobs from stealing or stealing the signal.
There are several ways to program a key fob based on the model and make. Some cars allow you to do this by yourself. However, most newer models require you to visit an expert locksmith or dealer in order to program a new key fob or additional one.
When you press the button on your key fob the microchip inside sends an encoded 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 drive.
Once the car has been associated with a particular fob, it will only accept signals from that device. Other fobs won't work with the car, even if they appear similar. This protects the integrity of the computer system that runs the vehicle and stops unauthorised key fobs from taking control over it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security knowledge that can only be found in the dealer service department. Certain aftermarket fobs, typically ones for older models with less advanced systems, can be programmed without the need for a dealer.
