There are a few different kinds of car key programming that can be done by locksmiths who are professionals. Certain types are more complex and require specialized tools. These tools are not generally available to the public and are only used by professionals. This type of programming is known as EEPROM Programming. It requires the ability to solder, electronic skills and a lot time.

This is because the new key hasn't been programmed into the vehicle's system. This can be quite costly. It's best to have two keys that work for the modern automobile so that you can program the replacement key if needed.

These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They come with diagnostic software that allows them to communicate with computers. They also feature a bidirectional user interface for working with an immobilizer system.

Transponder Chips
If your car is made within the past 20 years, chances are it contains a transponder chip within of it. It's a small piece of plastic inside the head of your key which contains a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal is then taken up by an antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to determine if the transponder chip that is in the key is the right one for your specific vehicle.
This is what prevents doing hot-wiring or altering the ignition system of your vehicle to start it. The chip in the key also verifies that you are the genuine owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys appear like regular keys made of metal but have caps made of plastic. The chip is inside the plastic portion of these keys. There are several different cuts such as a standard cut a Laser cut (also known as a sidewinder or Ford Tibbe) and the Ford Tibbe.
A circuit within the induction coil emits a signal when the transponder is inserted into the ignition barrel. The signal will then get absorbed by the chip, causing it to transmit a signal to the car. If the computer inside the car recognizes the signal as valid it will turn off the car immobilizer so that the engine can start.
If the car doesn't recognize the transponder as the correct signal, it won't start the engine and will alert you with flashing lights and siren. This feature is designed to discourage people from trying to hack into the vehicle, but it isn't a foolproof security measure. A skilled and determined thief might be able escape this security system by using a special device to take over the signal.
You can see that a transponder is a great option. All car owners should take this into consideration if they wish to protect their investment and decrease the chance of theft.
Key Fobs
Key fobs today can offer more than locking 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 extra features could make it difficult to locate your car keys.
Key fobs are able to communicate with each other and the car using radio frequencies that are transmitted through an antenna that is located in the middle of the key. The transmission is encrypted, which helps keep others from stealing and re-transmitting the signal.
There are many ways to program a key fob, based on the vehicle's make and model. Certain cars let you do this by yourself. However, the majority of newer models require you to visit a professional locksmith or dealer in order to program a new key fob or an additional one.
When you press the button on your key fob it transmits an encoded code to the car's radio that it is paired with. The receiver then compares this information with the 'allowed' signals stored in the fob and then either locks or opens the door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to function.
Once the car is linked with a specific fob, it will only receive signals from that device. Other fobs will not work with the car, even though they appear similar. This safeguards the integrity of the computer system of the vehicle and stops the use of unauthorized key fobs to gain control over it.
Most newer car dealers will only work on a car with original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security expertise that can only be found in the dealer's service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems can be programmed by customers without the need of an authorized dealer.
