The newer models have computers that have improved anti-theft security. In order to work properly, these cars require that a transponder chip-integrated key be programmed into the vehicle by a certified locksmith or car dealer/mechanic.
programming car key are able to perform a variety of different types of programming for car keys. Some are extremely complicated and require sophisticated tools. These tools are not accessible to the general public and are used only by professionals. This kind of car key programming is known as EEPROM Programming and requires soldering, electronic expertise and a lot of time.
Other kinds of car key programming are much easier and can be done by the average person. These are usually done by using the diagnostics port on the car, that can be accessed using a special key-fob-programming tool.

Key Programmers
Modern cars require a key-programming process to initialize their vehicle's systems and start the car. In some cases the key needs to be programmed by an auto locksmith or a dealer. The key may not work properly or it may not even start the car in any way. This is because the new key has not been programmed to the car's system. This can be quite expensive. This is why it's a good idea to have two keys working for modern vehicles and have the replacement key programmed if needed.
A keyprogrammer can reprogram the transponder chip on the new mechanical key or key fob. It is also able to clone information from an existing key, allowing duplicates to be created. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that allows them to communicate with the computer as well as bidirectional interfaces to work with the immobilizer system.
There are a myriad of types of keyprogrammers available on the market. They come in all sizes, shapes, and colors. Some are cheap, while others are very sophisticated and can cost thousands of dollars. Some are specifically designed for certain types of vehicles and offer advanced diagnostics for the vehicle's electronic systems.

Transponder Chips
Transponder chips can be found in vehicles manufactured within the last 20 years. It's the tiny piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own.
When activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then absorbed by the special antenna that is positioned around the ignition barrel of your car. This allows the vehicle's computer system to determine if the transponder chip inside the key is the correct one for the car you have.
This prevents the vehicle from being started through hot-wiring or tampering. The chip inside the car key confirms that the owner is the person who is the owner of the vehicle. This can reduce car theft.
Transponder keys resemble normal keys but have a plastic cap. The chip is located inside the plastic portion of these keys. There are several different cuts that are a standard cut, laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe.
A circuit within the induction coil will emit a signal when the transponder is put into the ignition barrel. The signal will then get absorbed by the chip and cause it to transmit a signal to the car. If the computer on the car detects this signal as the correct one, it will turn off the vehicle immobilizer and allow the engine to start.
If the car does not recognize the transponder signal as being the right one, it will stop the engine from running and will notify you by flashing its lights and sounding siren. This function is designed to discourage individuals from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and determined thief could still evade this system using a special device that intercepts the signal.
You can see that the transponder is a good option. Every car owner must take this into consideration if they wish to protect their investment and decrease theft risk.
Key Fobs
Key fobs today can do more than just lock and unlock doors. They can also start your car from a distance, make chirping sounds to help locate the car, or switch on the heated steering wheel. A lot of these features may appear convenient however they could make it harder for you to keep the track of your car keys.
Key fobs are able to communicate with each other and with the car through radio frequencies which are transmitted by an antenna that is located in the center of the key. This signal is encrypted to prevent others from intercepting or replicating the signal.
There are many ways to program a key fob, based on the model and make. It is possible to do this yourself, however most modern cars require that you visit a dealer or professional locksmith to program a replacement or an additional fob.
When you hit the button on a key fob it transmits a code to the car's radio that it is paired with. The receiver compared this information to the 'allowed' signals in the fob and then either opens or locks the door. If the data does not match the fob's information, the car won't be allowed to operate.
After the car has been connected to a specific fob, it only accepts signals from that device. Other fobs will not work with the car, despite the fact that they appear similar. This is to safeguard 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 dealers who are newer will only work on cars with original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security expertise that is only available in the dealer's service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems can be programmed by consumers without the need of dealers.
