The reason for this is that the new key has not been programmed to the car's system. This can be very costly. This is why it's a good idea to always have two keys working for modern vehicles and to have the replacement key programmed if needed.
A keyprogrammer is a tool which can reprogram the transponder chip on the form of a new key fob or mechanical key. It is also able to copy the data of an existing key and allow duplicate keys to be made. 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 also provide an interface that works bidirectionally with the immobilizer system.
There are a myriad of types of keyprogrammers available on the market. They are available in a variety of sizes, shapes, and colors.

Transponder Chips
Transponder chips are likely be found in vehicles manufactured in the last 20 years. It's the tiny plastic piece in the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to your car.
When it is activated by an electromagnetic field, the chip emits a low level signal. This signal is then received by a specific antenna that is attached to the ignition barrel. The computer system in the vehicle will then confirm that the chip in the key's transponder is the correct one for your car.
This is what stops doing hot-wiring or altering the vehicle's ignition system to get it started. The chip in the key also confirms that you are the legitimate owner of the vehicle. This can reduce car theft.
Regular transponder keys are shaped like regular metal keys with an outer layer of plastic. The chip itself is housed within the plastic part of the key and there are different types of cuts on these keys: a regular cut laser cut (also called a sidewinder key), or a Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is received by the chip which sends a signal to the vehicle. If the onboard car computer recognizes this signal as being the right one, it will disable the vehicle immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder as the correct signal, it won't start the engine, and will alert you with flashing lights and a siren. This feature is designed to discourage people from tampering with the vehicle. However, it is not an unbreakable security measure. A skilled and skilled criminal could still bypass this system with a specially designed device that detects the signal.
As you can see there are quite a number of advantages to having transponder keys. This is something that all vehicle owners should consider if they want to protect their investment and minimize the risk of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also turn on the vehicle from a distance, make chirping sounds to aid in finding a car, or turn on the heated steering wheel. A lot of these features might seem useful but they could make it difficult for you to keep the keys to your car.
Key fobs use radio frequencies to communicate with each other and with the car. These frequencies are transmitted through a small antenna located within the middle of the key. This communication is encrypted, which helps to prevent others from intercepting and re-transmitting the signal.
There are many ways to program a key fob based on the vehicle's model and make. You may be able to do it yourself, but most newer automobiles require a dealer or professional locksmith to program a replacement or a second fob.
When you hit the button on a key fob it transmits an informational code to the car's radio that it is paired with. The receiver then compares the data with the 'allowed signals' stored in the key fob, and then it opens or closes the car's door. If the data does not match, the car will not be allowed to operate.
After the car has been associated with a particular fob, it can only receive signals from that device. In turn, other fobs won't work with the vehicle, even though they appear similar. This safeguards the integrity of the computer system in the vehicle and stops unauthorized key fobs gaining control over it.
Most newer car dealerships will only accept cars that have original fobs, or genuine replacements offered by the manufacturer. The reason for this is that the only place with the experience to design an appropriate replacement fob is a dealer's service department. However, some aftermarket fobs typically for older models with less sophisticated systems -- can be programmed by the consumer without the need for an authorized dealer.
