Modern models come with computers that have improved security against theft. 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 to cars. Some are very complex and may require sophisticated tools. These tools are generally not accessible to the general public and are used only by professionals. This type of programming is known as EEPROM Programming. It requires the ability to solder, electronic skills and a significant amount of time.
Other kinds of programming for car keys are much simpler and can be accomplished by the average person. They are typically done using the diagnostics port on the car, that can be accessed using the key-fob-programming device. This procedure can be carried out by a professional locksmith with the help of an online guide or the car's owner manual.

Key Programmers
Modern cars require a key-programming process to initialize their vehicle's systems and then start the vehicle. In some instances keys must be configured by the dealer or auto locksmith. The key may not work correctly or will not start the car at all. The reason for this is that the new key has not been programmed to the car's system, and this could be quite costly. This is why it's a great idea to have two keys that work for a modern car, so you can get the replacement key programmed if required.

Keyprogrammers are devices that can recode the transponder chip in an entirely new key fob or mechanical key. It can also clone data from an existing key to create duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that enables them to communicate with the computer as well as bidirectional interfaces to work with the immobilizer system.
There are a variety of keyprogrammers on the market. They come in all sizes, shapes, and colors. Some keyprogrammers are cheap while others can cost thousands of dollar. Certain models are specifically designed for automobiles and offer advanced diagnostics of the vehicle's electronic system.
If you're interested in programming an entirely new key for your vehicle, refer to the owner's manual for instructions on the procedure. Certain manufacturers have proprietary software that allows only dealers to make new keys. Other manufacturers make it easy for anyone to do.

These are less expensive than going to the dealership, but they're still expensive. Before you purchase one do some research on the seller. Some aren't trustworthy and could cause damage to your vehicle.
Transponder Chips
If your car is made within the last 20 years, chances are it contains a transponder chip within of it. It's the small plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to your car.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then taken up by an antenna attached to the barrel of ignition. car keys programmer allows the computer in your vehicle system to verify that the transponder chip that is in the key is the correct one for your particular car.
This stops the vehicle from being started by either hot-wiring or by tampering. The chip inside the car key verifies that the owner is the one who owns the vehicle. This can help to reduce the possibility of theft from your vehicle.
Regular transponder keys are shaped like regular metal keys with an outer layer of plastic. The chip itself is housed inside the plastic portion of the key and there are a few different cuts that can be found on these keys: a regular cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer in the car detects the signal as correct, it will disable vehicle immobilizer to allow the engine start.
If the car doesn't recognize the transponder as a valid signal, it won't start the engine and warn you with flashing lights and a siren. This feature is designed to discourage people from attempting to tamper with the vehicle, but it isn't a foolproof security measure. A skilled and committed thief could still be able to escape this security system by employing a device designed to take over the signal.
You can see that the transponder is an excellent option. All car owners should take this into consideration when they want to safeguard their investment and minimize theft risk.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also turn on the car remotely, make chirping noises to aid in finding the car or turn on the heated steering wheel. A lot of these additional features might seem useful, but they can also make it harder for you to keep track of your car keys.
Key fobs are able to communicate with each other and with the car through radio frequencies that are transmitted through an antenna that is located in the center of the key. The transmission is encrypted, which helps keep others from stealing and re-transmitting the signal.
Keyfobs can be programmed in various ways based on the model and brand of your vehicle. Some cars allow you to do this yourself. However, the majority of newer models require you to visit a professional locksmith or dealer for them program a replacement key fob or additional one.
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 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 run.
Once the car is paired with a particular fob, it will only receive signals from that device. Other fobs will not work with the car, even though they look identical. This protects the integrity of the vehicle's computer system and to prevent the use of unauthorized key fobs to gain control over the vehicle.
Most dealerships with newer cars will only work with vehicles that have original fobs, or genuine replacements supplied by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security skills that is only available in the dealer service department. Some fobs from the aftermarket, especially those from older models that have less sophisticated systems, can be programmed without the need for a dealer.
