These cars require a transponder-chip integrated key to be programmed by a professional locksmith mechanic or dealer to function properly.
There are many types of car keys programming that can be performed by professional locksmiths. Certain are complicated and require specialized tools. These tools are usually not available to the general public and are only used by professionals. This kind of programming is known as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a significant amount of time.

Key Programmers
Modern cars require a key-programming method to set up their systems and start the car. In some cases, the key will need to be programmed by an auto locksmith or dealer. The key might not function correctly or will not start the car at all. This is because the key has not yet been programmed into the car's system. smart key programming can be costly. This is why it's a good idea to always have two working keys for modern vehicles and have the replacement key programmed if necessary.
A keyprogrammer is a tool that recodes the transponder chip on the form of a new key fob or mechanical key. It can also clone 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 are equipped with diagnostic software that enables them to communicate with computers, and they also have a bidirectional interface for working with the immobilizer system.
There are many different types of keyprogrammers available on the market. They are available in a variety of shapes, sizes and colors.

Transponder Chips
Transponder chips can be found in cars that were manufactured within the past 20 years. It's a small piece of plastic inside the head of your key that contains an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal is then taken up by an antenna attached to the barrel of ignition. This allows the vehicle's computer system to confirm that the transponder chip that is in the key is the right one for your specific vehicle.
This prevents the vehicle from being started through either hot-wiring or by tampering. The chip in the car key ensures that the owner is the person who owns the vehicle. This helps to prevent car theft.
Regular transponder keys are designed 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 a few different cuts that can be found on the keys: a cut laser cut (also known as a sidewinder key) or Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer inside the car detects the signal as being correct, it will disable vehicle immobilizer to allow the engine start.
If the car does not recognize the transponder signal as the right one, it will prevent the engine from starting and will notify you by flashing its lights and sounding an alarm. This feature is designed to discourage people from tampering with the vehicle. However it isn't an absolute security measure. A skilled and determined thief could still bypass this system with a specially designed device that detects 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 when they want to safeguard their investment and minimize the chance of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making chirping sounds to help find a car in a parking space, today's key fobs can also turn on a heated steering wheel or open all windows with a single click. A lot of these additional features may appear convenient but they could make it difficult for you to keep track of your car keys.
Key fobs use radio frequencies to communicate with one another and with the car. The frequencies are transmitted by a small antenna in the middle of the key. The transmission is encrypted, which helps prevent others from intercepting and re-transmitting the signal.
There are a few different ways to program a key fob based on your vehicle's model and make. You may be able to do it yourself, but most newer automobiles require a locksmith shop or a professional to program a replacement or a second fob.
When you hit the button on a key fob the microchip inside sends an encoded code to the car's receiver that it is linked to. The receiver compares this information to the 'allowed' signals stored inside the fob, and either opens or closes the door. If the data doesn't match an chirping sound is heard and the car isn't able to function.
Once the car is paired with a particular fob, it will only receive signals from that device. In turn, other fobs won't work with the vehicle even if they appear similar. This protects the integrity of the computer system that runs the vehicle and stops unauthorized key fobs gaining control of it.
The majority of newer dealers will only work on a car with original fobs or genuine replacements sold by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security skills that is only available in the dealer service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems can be programmed by consumers without the need of dealers.
