The cars require a transponder chip-integrated key to be programmed by a professional locksmith, car dealer or mechanic to function properly.
Professional locksmiths can perform a variety of different types of programming for keys for cars. Some are extremely complicated and require sophisticated tools. These tools are usually not available to the general public and are only used by professionals. This kind of programming is referred to as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot of time.
Other types of programming a key car keys are much easier and can be done by anyone who is able to.

You will have to pay the dealer for programming keys and replacement keys if you don't.
Key Programmers
Modern vehicles typically require a key programming procedure to initialize the vehicle's system and allow the vehicle to begin. In many cases the key needs to be configured by the dealer or auto locksmith. This is because the key might not function properly, or it will not start the car at all. This is because the new key has not been programmed to the automobile's system - and this can be very costly. It is best to have two keys that work with your current car so you can program the replacement key when needed.
Keyprogrammers can recode the transponder chip on an entirely new mechanical key or key fob. It is also able to clone information from an existing key and allow duplicate keys to be made. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They come with diagnostic software that allows them to communicate with the computer and also provide a bidirectional interface for working with the immobilizer system.
There are a variety of keyprogrammers available on the market. They are available in a variety of shapes, sizes and colors.

If you are unable to program the new key yourself and you are unable to do it, then request your dealer to do it, but it will cost you a lot. Another option is to buy an online keyprogrammer. They are less expensive than visiting a dealership however, they aren't inexpensive. Before buying one do some research on the seller. Some aren't reliable and may damage your vehicle.
Transponder Chips
If your car was manufactured in the last 20 years, chances are it has a transponder inside of it. It's the small plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
When activated by an electro-magnetic field, the chip emits a low-level signal. This signal then gets taken up by the antenna that is positioned around the barrel that controls your ignition in your vehicle. The computer system in the vehicle will then confirm that the key's transponder chip is the correct one for your vehicle.
This is what prevents hot-wiring or tampering with the vehicle's ignition system to turn it on. The chip inside the car key verifies that the owner is the one who is the owner of the vehicle. This will help reduce car theft.
Regular transponder keys are designed like regular metal keys with a plastic top. The chip is contained within the plastic part of these keys. There are various cuts: a standard cut and program car keys, Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.
The circuit in the induction coil emits an electrical signal when the transponder is placed in the an ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the computer in the car recognizes the signal as being correct it will turn off the car immobilizer so that the engine can start.
If the car isn't able to recognize the transponder as the correct signal, it will not start the engine and alert you with flashing lights and an alarm. This function is designed to discourage those who would attempt to alter the vehicle. However, it is not a foolproof measure of security. A skilled and skilled criminal could still evade this system by using a specific device that blocks the signal.
You can see that the transponder is an excellent option. This is something that all vehicle owners should think about if they are looking to safeguard their investment and minimize the chance of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also start the car remotely, emit chirping sounds to aid in finding a car or turn on the heated steering wheel. These extra features could make it difficult to find your car keys.
Key fobs are able to communicate with each other and with the car through radio frequencies that are transmitted via an antenna that is located in the center of the key. The signal is encrypted to prevent others from stealing or stealing the signal.
Keyfobs can be programmed in a variety of ways depending on the model and brand of your car. Certain models allow you to do this by yourself. However, most newer models require you to visit an expert locksmith or dealer in order for them program a replacement key fob or additional one.
When you press the button on a key fob, the microchip transmits signals to the receiver inside the vehicle with which it is linked. The receiver compares the information with the 'allowed signals' stored on the key fob and then locks or opens the car door. If the information isn't in line, a chirping sound is heard and the car isn't able to function.
After the car has been associated with a particular fob, it will only accept signals from that device. This means that other fobs won't be able to work with the vehicle even though they look the same. This ensures the security of the computer system that runs the car and blocks unauthorised key fobs from taking control over it.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. The reason for this is that the only place with the knowledge to create the replacement fob is a dealer's service department. Some fobs from the aftermarket, especially ones for older models that have less sophisticated systems, can be programmed without the need for a dealership.
