Newer models are equipped with computers that are enhanced security against theft. In order to work properly, these cars require that a transponder chip key be programmed into the vehicle by a professional locksmith or car dealer/mechanic.
Professional locksmiths can perform various kinds of programming for keys to cars. Certain types are more complex and require advanced tools. These tools are not generally accessible to the general public and are utilized only by professionals. This kind of key programming is called EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time.
Other kinds of car key programming are much easier and can be done by the average person. They are typically done using the onboard diagnostics port, which can be accessed with the key-fob-programming device.

Key Programmers
Modern cars frequently require a key programming procedure to start the system of the vehicle and allow the vehicle to start.

The reason for this is that the new key has not been programmed to the car's system. This can be quite expensive. It is best to have two keys that work for the modern automobile so that you can program the replacement key when needed.
Keyprogrammers can recode the transponder chip on the new mechanical key or key fob. It is also able to copy the data of an existing key and allow duplicate keys to be created. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with computers. They also have a bidirectional interface that works with an immobilizer system.
There are a myriad of types of keyprogrammers available on the market. They are available in a variety of sizes, shapes, and colors.

Transponder Chips
Transponder chips can be found in cars manufactured within the last 20 years. It's the tiny plastic piece in the head of your car key that contains an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then taken up by the antenna that is attached to the barrel that controls your ignition in your vehicle. The computer system in the vehicle can then verify that the transponder chip of the key is the right one for your car.
This stops the vehicle from being started by hot-wiring, or by altering the key. The chip in the key also confirms that you are the genuine owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys resemble normal keys but have a plastic cap. The chip is contained within the plastic part of the keys. There are various cuts such as a standard cut Laser cut (also known as a sidewinder or Ford Tibbe) and a Ford Tibbe.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal is taken up by the chip, which sends a signal to the vehicle. If the car's computer detects this signal as the right one, it will turn off the vehicle immobilizer and allow the engine to start.
If the vehicle does not recognize the transponder signal as the correct one, it will prevent the engine from running and will notify you by flashing its lights and sounding an alarm. This system is designed to deter those who would attempt to alter the vehicle. However, it is not a foolproof measure of security. A skilled and determined criminal may still be able to bypass this system by using a special device to detect the signal.
As you can see there are quite number of benefits to having a transponder key. This is something that all vehicle owners should consider if want to protect their investment and minimize the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making noises to aid in finding the car in a parking space, today's key fobs can also switch on a heated steering wheel, or open all windows with just a single push. These extra features could make it difficult to locate your car keys.
Key fobs use radio frequencies to connect with one another and the car. These frequencies are sent by a small antenna within the middle of the key. This communication is encrypted, which helps stop others from stealing and retransmitting the signal.
You can program a keyfob in different ways based on the model and make of your car. You may be able to do it yourself, however most modern cars require that you visit a locksmith shop or a professional to program a replacement or additional fob.
When you press the button on a key fob the microchip transmits an indication to the receiver in the vehicle that it is paired. The receiver compared this information with the 'allowed' signals stored on the fob and either locks or opens the door. If the data doesn't match an chirping sound is heard and the car isn't allowed to operate.
Once the car is paired with a specific fob, it will only accept signals from that device. In turn, other fobs will not work with the vehicle even if they look the same. This ensures the security of the computer system that runs the car and blocks unauthorised key fobs from taking control over it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security knowledge that can only be found in the dealer service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems -- can be programmed by consumers without the need of dealers.
