Professional locksmiths can perform various types of programming for keys to cars. Certain types are more complex and require specialized tools. These tools are generally not accessible to the general public and are only used by professionals. This type of programming is known as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot of time.
Other kinds of car key programming are much easier and can be accomplished by anyone who is able to.

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 the computer and also provide an interface that works bidirectionally with the immobilizer system.

Transponder Chips
If your car is made within the past 20 years, chances are it contains a transponder chip within of it. This is a little piece of plastic inside the head of your key which contains an RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is taken up by an antenna attached to the ignition barrel. The computer system of the vehicle can then verify that the transponder chip of the key is the correct one for your vehicle.
This stops the vehicle from being started through hot-wiring, or by altering the key. The chip inside the key also proves that you are the genuine owner of the vehicle. This will help reduce car theft.
Transponder keys appear like regular keys made of metal but they have a plastic cap. The chip is housed inside the plastic portion of the key, and there are different cuts that can be found on these keys: a regular standard cut laser cut (also called a sidewinder key) or Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal will then get taken up by the chip, causing it to transmit a signal back to the car. If the onboard car computer detects this signal as the correct one, it will shut down the vehicle immobilizer and allow the engine to start.
If the vehicle does not recognize the transponder signal as being the proper one, it will prevent the engine from running and will notify you by flashing its lights and sounding siren. This is designed to discourage people from attempting to tamper with the vehicle, however it's not a 100% security measure. A skilled and determined criminal may still be able to bypass this system by employing a device designed to take over the signal.
It is evident that a transponder is a great option. This is something that all car owners should consider if they want to protect their investment and decrease the risk of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also start the vehicle from a distance, make chirping sounds to help locate cars, or turn on the heated steering wheel. A lot of these features may appear convenient however they could make it more difficult to keep track of your car keys.
Key fobs use radio frequencies to communicate with each other and with the car. The frequencies are transmitted via a small antenna that is located within the middle 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 depending on the vehicle's model and make. You can sometimes do this yourself, but the majority of newer automobiles require a dealer or professional locksmith to program a replacement or a second fob.
When you press the button on a key fob the microchip sends an indication to the receiver in the vehicle with which it is linked. The receiver compared the information with the permitted signals stored in the key fob, and then opens or locks the car's doors. If the information doesn't match, the car will not be allowed to operate.
After the car has been associated with a particular fob, it will only accept signals from the device. Other fobs won't work with the car, even though they look like. This protects the integrity of the car's computer system and prevent unauthorised key fobs from taking control over the vehicle.
Most newer car dealers will only work on a car with original fobs or genuine replacements supplied by the manufacturer. The reason for this is that the only place that has the knowledge to create a replacement fob is in the service department of a dealer. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems can be programmed by the consumer without the need of dealers.
