These cars require a transponder-chip integrated key to be programmed by a professional locksmith car dealer or mechanic in order to function properly.
Professional locksmiths can perform various types of programming for keys for cars. Certain are complicated and require advanced tools. These tools are not generally available to the public and are utilized only by professionals. This kind of key programming is called EEPROM Programming. It requires the ability to solder, electronic skills and a lot of time.
Other kinds of key programming can be done by anyone. They can be done by using the onboard diagnosis port, which is accessible via a tool specifically designed for key-fob programming. Locksmiths can execute this method with the assistance of an online guide and the owner's manual.

A keyprogrammer can recode a transponder chip on a new mechanical key or key fob. It is also able to copy the data from an existing key which allows duplicate keys to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that allows them to communicate with computers. They also have a bidirectional user interface to work with an immobilizer system.

Transponder Chips
If your car is made within the last 20 years, it is likely that it has a transponder chip inside of it. This is the little plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
When it is activated by an electro-magnetic field the chip emits a low-level signal. The signal is then taken up by an antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to determine if the transponder chip inside the key is the right one for your particular car.
This is the reason why hot-wiring or tampering with the ignition system of your vehicle to start it. The chip inside the car key ensures that the owner is the person who owns the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular metal keys with an outer layer of plastic. The chip is contained inside the plastic portion of the key and there are different kinds of cuts available on these keys: a cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal will be absorbed by the chip and cause it to send a signal back to the car. If the computer inside the car is able to recognize the signal as valid it will turn off the vehicle immobilizer, allowing the engine to start.
If the car does not recognize the transponder signal as the correct one, it will keep the engine from starting and will notify you by flashing its lights and sounding siren. This feature is designed to discourage those who would attempt to alter the vehicle. However it isn't an absolute security measure. A determined and skilled thief can still get around this system using a special device that blocks the signal.
You can see that a transponder is a great option. Every car owner must take this into consideration in order to safeguard their investment and reduce the chance of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also start the car remotely, make chirping noises to help locate a car, or turn on the heated steering wheel. These extra features can make it difficult for you to locate your car keys.
Key fobs are able to communicate with each other and the car using radio frequencies that are transmitted via an antenna that is located in the center of the key. The signal is encrypted to prevent others from intercepting or replicating the signal.
Keyfobs can be programmed in a variety of ways depending on the model and make of your vehicle. It is possible to do this yourself, but the majority of newer vehicles require a locksmith shop or a professional to program a replacement or additional fob.
When you press the button on a key fob the microchip sends a signal to the receiver inside the vehicle with which it is paired. The receiver compared the information with the 'allowed signals' that are stored in the key fob, and then locks or opens the car's door. If the information doesn't match, a chirping sound is heard and the car isn't allowed to operate.
Once the car is paired with a specific fob, it will only receive signals from that specific device. This means that other fobs won't work with the vehicle even if they appear similar. This protects the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.
The majority of car key reprogram (you could try these out) dealers who are newer will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security skills that can only be found 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 of a dealership.
