Professional locksmiths can perform a variety of different types of programming for keys for cars. Certain are complicated and require advanced tools. These tools are not accessible to the general public and are used only by professionals. This kind of programming is referred to as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot time.

The key might not function correctly or will not start the vehicle at all. This is because the key has not yet been programmed into the vehicle's system. This can be costly. This is why it's a great idea to have two keys that work for modern vehicles and have the replacement key programmed if required.
Keyprogrammers can recode the transponder chip of a new mechanical key or key fob. It is also able to clone data from an existing key which allows duplicate keys to be created. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They have diagnostic software that enables them to communicate with the computer as well as bidirectional interfaces to work with the immobilizer system.
There are many different types of keyprogrammers available on the market. They come in all shapes, sizes and colors.

Transponder Chips
Transponder chips can be found in cars that were manufactured within the past 20 years. This is a little plastic thing on the back of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then received by a specific antenna that is attached to the ignition barrel. The computer system of the vehicle can then verify that the transponder chip of the key is the right one for your car.
This stops the vehicle from starting by either hot-wiring or by manipulating. The chip inside the key ensures that the owner is the one who is the owner of the vehicle. This can reduce car theft.
Regular transponder keys are shaped like regular keys, but with a plastic top. The chip is contained within the plastic part of the key, and there are different types of cuts on these keys: a regular standard cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil sends out the signal. The signal is received by the chip which then transmits a signal the vehicle. If the onboard car computer detects this signal as the right one, it will disable the vehicle immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder as a valid signal, it won't start the engine and warn you with flashing lights and siren. This feature is designed to discourage people from trying to alter the vehicle, however it is not a foolproof security measure. A determined and skilled thief could still bypass this system by using a specific device that intercepts the signal.
As you can see there are quite number of benefits to having transponder keys. All car owners should consider this when they want to safeguard their investment and reduce theft risk.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making chirping sounds to help find a car in a parking space keys of today can also activate a heated steering wheel, or open all windows with a single button press. A lot of these additional features might seem useful, but they can also make it more difficult to keep track of your car keys.
Key fobs communicate with each with the car via 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 stealing or modifying the signal.
There are several ways to program a key fob based on your vehicle's make and model. Some cars allow you to do this by yourself. However, car key programming of modern models require you to visit an expert locksmith or dealer in order to program a new key fob or an additional one.
When you hit the button on a key fob it transmits an encoded code to the car's receiver that it is paired with. The receiver then compares this information to the signals that are allowed on the fob and either locks or opens the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to function.
Once the car has been connected to a specific fob, it will only accept signals from the device. This means that other fobs will not work with the vehicle even though they appear similar. This is to safeguard the integrity of the vehicle's computer system and prevent unauthorized key fobs from gaining control of the vehicle.
The majority of newer dealers will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer. It is because the only place that has the experience to design an appropriate replacement fob is the service department of a dealer. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems can be programmed by consumers without the need for a dealership.
