In order to work correctly, these vehicles require that a transponder chip-integrated key be programmed into the vehicle by a professional locksmith or car dealer/mechanic.
Professional locksmiths can perform various kinds of programming for keys to cars. Some are very complex and require sophisticated tools. These tools aren't usually available to the public and are used only by professionals. This kind of key programming is called EEPROM Programming. It requires expertise in soldering, electronic knowledge and a significant amount of time.
Other kinds of key programming can be performed by anyone. They are typically accomplished by using the diagnostics port on the car, which can be accessed with the key-fob-programming device. Locksmiths can execute this method with the help of a guide online and the owner's manual.

The key might not function properly or not start the car at all. 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 great idea to have two keys working for a modern car and to have the replacement key programmed if needed.
Keyprogrammers are devices which can reprogram the transponder chip in the form of a new mechanical or key fob key. It is also able to copy the data from an existing key which allows duplicate keys to be created. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They come with diagnostic software that allows them to communicate with a computer. They also feature a bidirectional user interface for working with an immobilizer system.
There are a variety of keyprogrammers available on the market. They come in all shapes, sizes and colors. Some keyprogrammers are cheap, while others may cost thousands of dollars. Some are made for specific automobiles and provide advanced diagnostics of the vehicle's electronic system.
If you're looking to program the new key into your vehicle, refer to the owner's manual to learn how to do it. Certain manufacturers employ proprietary technology that guarantees that the dealership is the only entity that can make new keys, but other manufacturers make it fairly easy for anyone to accomplish it themselves.

Transponder Chips
Transponder chips can be found in vehicles manufactured within the last 20 years. It's the tiny plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then received by a specific antenna attached to the ignition barrel. This allows the vehicle's computer system to determine if the transponder chip inside the key is the right one for your specific vehicle.
This stops the vehicle from being started by either hot-wiring or by altering the key. The chip inside the key also confirms that you are the legal owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys that are regular in shape like regular keys and have an outer layer of plastic. The chip is contained within the plastic portion of the keys. There are fob key programming that are a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe), and the Ford Tibbe.
The circuit in the induction coil will emit signals when the transponder is placed in the the ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer in the car recognizes the signal as correct, it will disable vehicle immobilizer so that the engine can start.
If the car doesn't recognize the transponder as a valid signal, it will not start the engine and will warn you with flashing lights and an alarm. This feature is designed to deter people from trying to hack into the vehicle, but it's not a 100% security measure. A skilled and determined criminal could still be able to escape this security system by using a special device to detect the signal.
As you can see there are quite a number of benefits to having transponder keys. All car owners 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 the vehicle from a distance, make chirping sounds to aid in finding the car or turn on the heated steering wheel. These additional features can make it difficult for you to locate your car keys.
Key fobs use radio frequencies to communicate with one another and with the car. The frequencies are transmitted via a small antenna that is located inside the middle of the key. This communication is encrypted, which helps to prevent others from intercepting and replicating the signal.
You can program a keyfob in various ways based on the model and make of your car. Some cars 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 a key fob's button, the microchip inside transmits an encoded code to the car's radio that it is linked to. The receiver compared this information to the signals that are allowed on the fob and either opens or locks the door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't able to function.

Once the car is linked with a specific fob it will only receive signals from that specific device. This means that other fobs will not work with the vehicle even if they look the same. This is to safeguard the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
Most dealerships with newer cars will only accept cars that have original fobs or genuine replacements supplied by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security knowledge that is only available in the dealer's service department. However, some fobs from the aftermarket typically for older models that have less sophisticated systems can be programmed by customers without the need for a dealership.
