Modern models come with computers that have improved anti-theft protection. To function properly, these cars require that a transponder chip key be programmed into the vehicle by a certified locksmith or mechanic/car dealer.
There are several types 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 accessible to the general public and are only used by professionals. This type of programming for car keys is referred to as EEPROM Programming and requires soldering, electronic knowledge and a lot of time.
Other types of key programming can be carried out by anyone. They are typically accomplished by using the onboard diagnostics port which can be accessed with the key-fob-programming device.

Key Programmers
Modern automobiles require a key-programming method to start the vehicle's system and to start the car. In certain instances, the key will need to be programmed by an auto locksmith or a dealer. This is because the key could not function correctly, or it will not start the car at all. The reason is because the new key hasn't been programmed into the vehicle's system, and this could be quite expensive. It is recommended to have two keys that are compatible for the modern automobile so that you can program the replacement key whenever required.
Keyprogrammers can recode the transponder chip of a new mechanical key or key fob. It can also clone data from an existing key to make duplicates. 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 computers and also provide an interface that works bidirectionally with the immobilizer system.
There are many different types of keyprogrammers available on the market and they are available in a variety of sizes and shapes. Some are inexpensive while others are sophisticated and can cost thousands of dollars.

They are cheaper than visiting a dealership but they aren't inexpensive. Before you purchase one, do some research on the seller. Some aren't trustworthy and could cause damage to your vehicle.
Transponder Chips
Transponder chips can be found in cars manufactured within the last 20 years. G28 's the tiny piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your car.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is attached to the ignition barrel of your vehicle. This allows the car's computer system to confirm that the transponder chip that is in the key is the correct one for the car you have.
This stops the vehicle from starting by hot-wiring or altering the key. The chip in the key also proves that you are the legitimate owner of the vehicle. This can reduce car theft.
Regular transponder keys are designed like regular metal keys with an outer layer of plastic. The chip is housed within the plastic part of the key, and there are a few different types of cuts on the keys: a cut laser cut (also called a sidewinder), or a Ford Tibbe key.
A circuit within the induction coil emits a signal when the transponder is placed in the ignition barrel. The signal is received by the chip which sends a signal to the vehicle. If the computer on the car recognizes this signal as the correct one, it will shut down the vehicle's immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine, and will warn you with flashing lights and an alarm. This feature is designed to discourage those who would attempt to alter the vehicle. However, it is not a foolproof measure of security. A determined and skilled thief can still get around this system with a specially designed device that intercepts the signal.
As you can see there are quite number of benefits to having transponder keys. This is something that all car owners should consider if they are looking to safeguard their investment and decrease the risk of theft.
Key Fobs
Key fobs today be more than just a way to lock and unlock doors. They can also start the car remotely, emit chirping sounds to aid in finding cars, or turn on the heated steering wheel. These extra features can make it difficult for you to find your car keys.
Key fobs utilize radio frequencies to communicate with one another and the car. These frequencies are transmitted via a small antenna that is located within the middle of the key. The communication is encrypted, which helps to 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. Some cars allow you to do this by yourself. However, the majority of newer models require you to visit a professional locksmith or dealer for them program a replacement key fob or an additional one.
When you hit the button on a key fob, the microchip inside transmits an encoded code to the car's receiver it is linked to. The receiver then compares this information to the signals that are allowed on the fob and either opens or closes the door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to operate.
Once the car is paired with a particular fob, it will only accept signals from that device. Other fobs will not work with the car, even if they look identical. This ensures the security of the computer system in the car and prevents unauthorized key fobs gaining control of it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. This is because preparing a replacement fob requires technological and security skills which can only be obtained in the dealer service department. Some aftermarket fobs, usually those from older models that have less sophisticated systems can be programmed with out the need for a dealer.
