The newer models have computers that have improved anti-theft security. To function correctly, these vehicles require a transponder chip-integrated key be programmed to the vehicle by a certified locksmith or mechanic/car dealer.
There are a few different 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 type of key programming is called EEPROM Programming. It requires the ability to solder, electronic skills and a significant amount of time.
Other types of key programming can be done by anyone. These are usually done by using the onboard diagnostics port, that can be accessed using an instrument for programming keys. This method can be performed by a trained locksmith with the help of an online guide or the car's owner manual.

Key Programmers
Modern vehicles typically require a key programming procedure to start the system of the vehicle and allow the vehicle to start. In a number of cases the key needs to be programmed by the dealer or an auto locksmith. This is because the key may not work properly or start the vehicle in any way. The reason is because the new key has not been programmed to the automobile's system - and this can be quite expensive. It is recommended to have two keys that work for the modern automobile so that you can program the replacement key when required.
A keyprogrammer can recode the transponder chip of an entirely new mechanical key or key fob. It is also able to copy the data of an existing key to create duplicates. 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 computers. They also have a bidirectional interface for working with an immobilizer system.
There are many different types of keyprogrammers that are available on the market. They are available in a variety of sizes, shapes, and colors. Some are inexpensive while others can cost thousands of dollar. Certain models are specifically designed for certain types of vehicles and can provide advanced diagnostics for the electronic systems of the car.
If you want to program the new key into your vehicle, consult the owner's manual to find out how. Certain manufacturers employ proprietary technology that ensures the dealership is the sole entity that can create new keys, but other manufacturers make it easy for anyone to do it themselves.

They are cheaper than visiting a dealer but they aren't inexpensive. Make sure you research the seller before purchasing one - some are not reliable and could damage your car.
Transponder Chips
If your car was manufactured within the past 20 years, then it has a transponder chip inside of it. It's a small plastic thing on the back of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
When it is activated by an electromagnetic field the chip emits a low-frequency signal. The signal is then received by a specific antenna attached to the ignition barrel. The computer system of the vehicle will then confirm that the key's transponder chip is the right one for your car.
This stops the vehicle from starting by either hot-wiring or by altering the key. The chip inside the key confirms that the owner is the one who owns the vehicle. This can help to reduce car theft.
Transponder keys that are regular in shape like regular keys and have a plastic top. The chip is contained within the plastic part of these keys. There are several different cuts that are a standard cut, Laser cut (also called a sidewinder or Ford Tibbe), and Ford Tibbe.
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 received by the chip which sends a signal to the vehicle. If the computer inside the car recognizes the signal as correct it will turn off the car 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 running and will notify you by flashing its lights and sounding an alarm. This feature is intended to discourage people from trying to hack into the vehicle, but it's not a 100% security measure. A skilled and determined thief can still get around this system using a special device that intercepts the signal.
As you can see there are quite few advantages to getting a transponder key. Every car owner should take this into consideration when they want to safeguard their investment and minimize the chance of theft.
Key Fobs
Key fobs today be more than just a way to lock and unlock doors. They can also start your car remotely, make chirping noises to aid in finding cars, or switch on the heated steering wheel. These additional features can make it difficult for you to find your car keys.
Key fobs communicate with one with the car via radio frequencies that are transmitted through a small antenna located in the middle of the key. The transmission is encrypted, which helps keep others from stealing and replicating the signal.
There are a few different ways to program a key fob based on the vehicle's model and make. You can sometimes do this yourself, but the majority of newer automobiles require an expert locksmith or dealer to program a replacement or additional fob.
When you press the button on your key fob, the microchip inside transmits an informational code to the car's receiver that it is paired with. The receiver compares the information with the 'allowed signals' that are stored on the key fob and then locks or opens the car door. If the information isn't in line an chirping sound is heard and the car isn't permitted to function.
Once the car is linked with a specific fob it will only accept signals from the device that is associated with it. Other fobs won't work with the car, despite the fact that they appear similar. This protects the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
The majority of newer dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security skills that can only be found in the dealer service department. Some aftermarket fobs, usually ones for older models with less sophisticated systems can be programmed with out the need for a dealer.
