There are many kinds of car key programming that can be performed by locksmiths who are professionals. Certain types are more complex and require advanced tools. These tools are not available to the general public and are used only by professionals. This type of programming is referred to as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot of time.

In some instances, the key will need to be programmed by an auto locksmith or dealer. The key may not function properly or it may not even start the car in any way. This is because the key has not yet been programmed into the car's system. This could be costly. This is why it's a good idea to have two working keys for a modern car and have the replacement programing key programmed when needed.
A keyprogrammer is a device which can reprogram the transponder chip in a new key fob or mechanical key. It is also able to copy the information from an existing key programing which allows duplicate keys to be created. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They have diagnostic software that allows them to communicate with computers, and they also have an interface that works bidirectionally with the immobilizer system.
There are a number of different kinds of keyprogrammers on the market and they come in all shapes and sizes. Some are inexpensive and others are sophisticated and could cost thousands of dollars.

They are less expensive than visiting a dealer however, they aren't expensive. Be sure to research the seller before purchasing one - some are not reliable and can damage your vehicle.
Transponder Chips
If your car was manufactured within the past 20 years, it is likely that it has a transponder chip inside of it. This is a little piece of plastic in the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal then gets absorbed by the special antenna that is attached to the barrel that controls your ignition in your car. This allows the car's computer system to verify that the transponder chip in the key is the correct one for your particular car.
This prevents the vehicle from starting by hot-wiring, or by tampering. The chip in the key also confirms that you are the legitimate owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Transponder keys resemble normal keys but have a plastic cap. The chip is housed in the plastic portion of the key and there are different types of cuts on these keys: a cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.
A circuit within the induction coil emits a signal when the transponder is inserted into an ignition barrel. The signal will then get absorbed by the chip and cause it to transmit a signal back to the car. If the computer inside the car detects the signal as being correct it will turn off the car immobilizer, allowing the engine to start.
If the car doesn't recognize the transponder as a valid signal, it will not start the engine, and will warn you with flashing lights and an alarm. This is designed to discourage people from attempting to hack into the vehicle, but it is not a foolproof security measure. A skilled and determined thief could still evade this system with a specially designed device that intercepts the signal.
It is evident that the transponder is a good option. This is something that all car owners should think about if they want to safeguard their investment and minimize the risk of theft.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also start your car remotely, make chirping noises to help locate the car, or turn on the heated steering wheel. A lot of these features might seem useful but they could make it difficult for you to keep the keys to your car.
Key fobs communicate with each other and the car using radio frequencies which are transmitted via an antenna that is located in the center of the key. This signal is encrypted to prevent others from stealing or modifying the signal.
You can program a keyfob in different ways based on the model and make of your vehicle. You can sometimes do this yourself, but the majority of newer vehicles require a locksmith shop or a professional to program a replacement or a second fob.
When you press the button on a key fob, the microchip sends a signal to the receiver in the car that it is paired. 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 doesn't match the signals, a chirping sound can be heard and the car isn't able to operate.
After the car has been paired with a specific fob, it will only accept signals from the device. In turn, other fobs will not work with the vehicle even though they look the same. This ensures the security of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control over it.
Most dealerships with newer cars will only accept vehicles that have 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 is only available in the dealer's service department. Some fobs from the aftermarket, especially ones for older models that have less sophisticated systems, can be programmed without the need for a dealer.
