These cars require a transponder-chip-integrated key to be programmed car keys by a professional locksmith, mechanic or dealer to function properly.
There are a few different types of car key programming that can be accomplished by locksmiths who are professionals. Some are extremely complicated and may require sophisticated tools. These tools are not accessible to the general public and are used only by professionals. This kind of programming is known as EEPROM Programming. It requires the ability to solder, electronic skills and a lot time.
Other types of key programming can be performed by anyone. These are done with the onboard diagnostic port, which is accessible by a specific tool for key-fob programming. Locksmiths can carry out this procedure with the help of an online guide as well as the owner's manual.

The key may not work properly or not start the vehicle in any way. The reason for this is that the new key has not been programmed to the automobile's system, and this could be very costly. It's best to have two keys that are compatible for the modern automobile so that you can program the replacement key whenever required.
Keyprogrammers can recode the transponder chip on an entirely new mechanical key or key fob. It is also able to clone data from an existing key which allows duplicate keys to be made. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software, which allows them to communicate with a computer. They also have a bidirectional user interface for working with an immobilizer system.
There are a number of different types of keyprogrammers available on the market and they are available in all sizes and shapes.

Transponder Chips
If your car was manufactured in the last 20 years, it is likely that 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 that has a unique code to the vehicle you own.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then received by a specific antenna that is attached to the ignition barrel. The computer system in the vehicle can then verify that the chip in the key's transponder is the right one for your car.
This is what stops from modifying or hot-wiring the ignition system of your vehicle to get it started. The chip inside the car key confirms that the owner is the one who is the owner of the vehicle. This can help to reduce car theft.
Regular transponder keys are shaped like regular keys, but with a plastic top. The chip is housed in the plastic portion of the key and there are a few different types of cuts on the keys: a standard cut laser cut (also known as a sidewinder key) or Ford Tibbe key.
The circuit in the induction coil will emit signals when the transponder is placed in the the ignition barrel. The signal will be taken up by the chip and cause it to transmit a signal to the car. If the computer onboard the car recognizes the signal as valid, it will disable vehicle immobilizer, allowing the engine to start.
If the vehicle doesn't recognize the transponder as the correct signal, it won't start the engine and will warn you with flashing lights and siren. This is designed to discourage people from attempting to hack into the vehicle, but it's not a 100% security measure. A determined and skilled thief can still get around this system by using a specific device that detects the signal.
As you can see there are quite number of advantages to having a transponder key programming key. This is something that all car owners should think about if they are looking to safeguard their investment and decrease the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making noises to aid in finding a car in a parking lot Key fobs today can also turn on a heated steering wheel, or roll down all of the windows with a single button press. These additional features can make it difficult to locate your car keys.
Key fobs utilize radio frequencies to connect with one another and the car. The frequencies are transmitted through a small antenna located in the middle of the key. The communication is encrypted, which helps to keep others from stealing and retransmitting the signal.
Keyfobs can be programmed in different ways based on the model and brand of your programmable car keys. Certain cars let you do it yourself. However, the majority of 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 a signal 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 opens or locks the car's doors. If the information isn't in line an chirping sound is heard and the car isn't allowed to operate.
Once the car is paired with a specific fob, it only accepts signals from the device. In turn, other fobs will not work with the vehicle even if they appear similar. This ensures the security of the computer system in the car and prevents unauthorized key fobs gaining control over it.
The majority of car dealers who are newer will only work on cars with 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 fobs from the aftermarket typically for older models that have less sophisticated systems -- can be programmed by the consumer without the need of a dealership.
