There are a few different types of car keys programming that can be done by locksmiths who are professionals. Certain are complicated and require specialized tools. These tools are not available to the general public and are used only by professionals. This kind of key programming is called EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot of time.
Other forms of programming car keys are much easier and can be accomplished by the average person. They are accomplished using the onboard diagnostic port, which can be accessed via a tool specifically designed for key fob programming.

Key Programmers
Modern cars typically require a key programming procedure to set up the car's system and allow the vehicle to start. In many cases the key needs to be programmed by the dealer or an auto locksmith. The key may not function properly or not start the car at all. This is because the key hasn't yet been programmed into the car's system. This can be expensive. This is why it's a great idea to have two working keys for modern vehicles 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 copy the data from an existing key, allowing duplicates to be created. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They come with diagnostic software, which allows them to communicate with a computer. They also feature a bidirectional user interface to work with an immobilizer system.
There are a variety of keyprogrammers that are available on the market. They come in all sizes, shapes, and colors. Some are inexpensive and others are sophisticated and could cost thousands of dollars. Some are designed for specific kinds of vehicles and provide advanced diagnostics for your vehicle's electronic systems.
Consult your owner's guide to learn how to program a key for your vehicle. Some manufacturers use proprietary technology that ensures the dealership is the only entity that can make new keys. However, other manufacturers make it fairly simple for anyone to do it on their own.
If you're unable to program the new key yourself and you are unable to do it, then request your dealer to do it, however it will cost a lot. You can also purchase an online keyprogrammer. These are cheaper than going to the dealership however, they're expensive. Make sure you investigate the seller prior to purchasing one - some are not reliable and can damage your vehicle.
Transponder Chips
Transponder chips can be found in vehicles manufactured within the last 20 years. This is a little plastic piece inside the head of your key which contains an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
When it is activated by an electromagnetic field the chip emits a low-level signal. This signal is then taken up by an antenna that is attached to the ignition barrel. This allows the computer in your vehicle system to confirm that the transponder chip in the key is the correct one for the car you have.
This stops the vehicle from starting by hot-wiring or manipulating. The chip inside the key ensures that the owner is the one who owns the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys that are regular in shape like regular keys, but with an outer layer of plastic. The chip is contained in the plastic portion of the key, and there are different kinds of cuts available on these keys: a regular standard cut laser cut (also called a sidewinder) or Ford Tibbe key.
A circuit inside the induction coil will emit an electrical signal when the transponder is inserted into ignition barrel. The signal will then get taken up by the chip and cause it to send a signal back to the car. If the computer on the car recognizes this signal as the correct one, it will disable the vehicle immobilizer and allow the engine to start.
If the car does not recognize the transponder signal as being the proper one, it will keep the engine from starting and will notify you by flashing its lights and sounding an alarm. This feature is designed to discourage those who would attempt to alter the vehicle. However it's not an unbreakable security measure. A skilled and determined thief can still get around this system using a special device that blocks the signal.
You can see that the transponder is a good option. Every car owner should consider this if they wish to protect their investment and decrease the risk of theft.
Key Fobs
Key fobs today be more than just a way to lock and unlock doors. They can also start the car remotely, make chirping noises to help locate cars, or switch on the heated steering wheel. These additional features can make it difficult to find your car keys.
Key fobs utilize radio frequencies to communicate with each other and the car. These frequencies are transmitted by a small antenna inside the middle of the key. This communication is encrypted to block other key fobs from stealing or modifying the signal.
Keyfobs can be programmed in different ways based on the model and make of your car. You can sometimes do this yourself, however most modern cars require that you visit a dealer or professional locksmith to program a replacement or a second fob.
When you press a key fob's button it transmits an encoded code to the car's receiver that it is linked to. The receiver then compares this information with the signals that are allowed on the fob and either locks or opens the door. If the data does not match the fob's information, the car won't be allowed to operate.
Once the car is paired with a specific fob, it will only accept signals from that device. Other fobs will not work with the car, even if they look identical. This protects the integrity of the computer system of the car and blocks unauthorized key fobs gaining control of it.
The majority of newer dealerships will only deal with cars with original fobs, or genuine replacements supplied by the manufacturer. This is because preparing a replacement fob requires technological and security expertise that is only available in the dealer service department. Certain aftermarket fobs, typically those from older models that have less sophisticated systems can be programmed without the need for a dealer.
