These cars require a transponder-chip integrated key to be programmed by a professional locksmith mechanic or dealer in order to function properly.
Professional locksmiths can perform various types of programming for keys to cars. Certain types are extremely complex and require sophisticated tools. These tools aren't usually accessible to the general public and are utilized only by professionals. This type of programming is known as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot time.

Key Programmers
Modern cars often require a key programming process to initialize the vehicle's system and allow the vehicle to begin. In many cases keys must be set up by the dealer or auto locksmith. The key might not function correctly or will not start the vehicle at all. This is because the key hasn't yet been programmed into the car's system. This can be costly. This is why it's a good idea to always have two working keys for a modern car and to have the replacement key programmed if needed.
Keyprogrammers can recode the transponder chip of a new mechanical key or key fob. It is also able to copy the data of an existing key, allowing duplicates to be created. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They have diagnostic software that allows them to communicate with computers as well as an interface that works bidirectionally with the immobilizer system.

If programming car key are unable to program the new key by yourself and you are unable to do it, then have your dealer do it, but it will be very costly. Another option is to purchase a keyprogrammer online. They are cheaper than going to a dealership, but still not expensive. Before purchasing one do some research on the seller. Some aren't trustworthy and could damage your vehicle.
Transponder Chips
If your car was built within the past 20 years, chances are it has a transponder chip inside of it. This is a little plastic piece on the back of your key that houses a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
When activated by an electro-magnetic field, the chip emits a low level signal. This signal is then taken up by the antenna that is positioned around the ignition barrel of your vehicle. The computer system of the vehicle will then confirm that the key's transponder chip is the correct one for your car.
This is what prevents doing hot-wiring or altering the vehicle's ignition system to start it. The chip inside the key also confirms that you are the legitimate owner of the vehicle. This can reduce car theft.
Regular transponder keys are designed like regular keys and have a plastic top. The chip is inside the plastic portion of these keys. There are a variety of cuts such as a standard cut 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 ignition barrel. The signal will be taken up by the chip, causing it to send a signal back to the car. If the computer inside the car recognizes the signal as being correct it will turn off the car immobilizer, allowing the engine to start.
If the vehicle does not recognize the transponder signal as being the correct one, it will stop the engine from running and will notify you by flashing its lights and sounding siren. This feature is designed to deter people from trying to tamper with the vehicle, however it is not a foolproof security measure. A skilled and determined criminal may still be able to bypass this system by using a device that can detect the signal.
As you can see there are quite a number of advantages to having a transponder key. Every car owner should take this into consideration in order to safeguard their investment and reduce the risk of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also start your car remotely, emit chirping sounds to help locate a car or turn on the heated steering wheel. These extra features can make it difficult for you to find your car keys.
Key fobs make use of radio frequencies to communicate with one another and the car. The frequencies are transmitted via a small antenna that is located inside the middle of the key. This communication is encrypted to stop others from stealing or modifying the signal.
There are many ways to program a key fob depending on the model and make. It is possible to do this yourself, however most modern automobiles require an expert locksmith or dealer to program a replacement or additional fob.
When you press the button on a key fob the microchip transmits signals to the receiver in the car that it is paired. The receiver compares the information with the permitted signals stored in the key fob and then opens or locks the car's doors. If the information doesn't match the fob's information, the car won't be allowed to drive.
Once the car has been connected to a specific fob, it will only accept signals from that device. Other fobs won't work with the car, even though they look identical. This protects the integrity of the car's computer system, and also to stop unauthorized key fobs from gaining control of the vehicle.
The majority of newer dealerships will only deal with cars with original fobs or genuine replacements offered by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security expertise that can only be found in the dealer service department. Some aftermarket fobs, usually ones for older models with less sophisticated systems, can be programmed without the need for a dealer.
