To function properly, these cars require that a transponder chip key be programmed to the vehicle by a professional locksmith or car dealer/mechanic.
Professional locksmiths can perform a variety of different types of programming for keys to cars. Certain types are extremely complex and require sophisticated tools. These tools are not accessible 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 time.

Key Programmers
Modern automobiles require a key-programming method to start the vehicle's system and to start the car. In some instances, the key must be programmed by the auto locksmith or dealer.

This is why it's a great idea to always have two working keys for a modern automobile and have the replacement key programmed when required.
A keyprogrammer can recode a transponder chip on a new mechanical key or key fob. It is also able to clone data from an existing key, allowing duplicates to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that allows them to communicate with computers. They also have a bidirectional user interface for working with an immobilizer system.
There are a myriad of types of keyprogrammers on the market. They are available in a variety of shapes, sizes and colors. Some are affordable and others are sophisticated and could cost thousands of dollars.

Transponder Chips
Transponder chips can be found in cars manufactured in the last 20 years. It's a tiny plastic piece on the back of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal is then absorbed by the special antenna that is fitted around the ignition barrel of your car. This allows the computer in your vehicle system to confirm that the transponder chip inside the key is the correct one for your particular car.
This prevents the vehicle from being started through either hot-wiring or by altering the key. The chip inside the key also confirms that you are the legitimate owner of the vehicle. www.g28carkeys.co.uk will help reduce car theft.
Transponder keys look like normal keys, but with a plastic cap. The chip itself is housed in the plastic portion of the key, and there are a few different cuts that can be found on these keys: a regular cut laser cut (also called a sidewinder), or a Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer in the car detects the signal as being correct it will turn off the car immobilizer to allow the engine start.
If the vehicle does not recognize the transponder signal as the proper one, it will stop the engine from running and will alert 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 unbreakable security measure. A skilled and determined criminal could still be able to bypass this system by employing a device designed to take over the signal.
It is evident that the transponder is a good option. This is something that all car owners should consider if want to protect their investment and minimize the risk of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also start the vehicle remotely, emit chirping sounds to aid in finding a car or switch on the heated steering wheel. These additional features can make it difficult to find your car keys.
Key fobs make use of radio frequencies to communicate with each other and the car. The frequencies are transmitted through a small antenna located within the middle of the key. The transmission is encrypted, which helps keep others from stealing and retransmitting the signal.
There are a few different ways to program a key fob based on your vehicle's make and model. It is possible to do this yourself, but most newer cars require that you visit a locksmith shop or a professional to program a replacement or an additional fob.
When you press the button on a key fob, the microchip sends an indication to the receiver inside the car with which it is paired. The receiver then compares the data with the 'allowed signals' stored on the key fob and then it opens or closes the car's door. If the information doesn't match, a chirping sound is heard and the car isn't allowed to function.
When a car is connected with a specific fob, it will only accept signals from the device that is associated with it. Other fobs will not work with the car, even though they appear similar. This helps to protect the integrity of the car's computer system and to prevent unauthorised key fobs from taking control of the vehicle.
Most dealerships with newer cars will only accept cars that have original fobs, or genuine replacements sold by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security skills which can only be obtained in the dealer service department. Some fobs from the aftermarket, especially those for older models with less sophisticated systems, can be programmed without the need for a dealer.
