The latest models come with computers that have improved anti-theft security. To function properly, these cars require that a transponder chip-integrated key be programmed into the vehicle by a certified locksmith or car dealer/mechanic.
There are several types of car keys programming that can be done by locksmiths who are professionals. Some are very complex and require sophisticated tools. These tools are usually not available to the general public and are used only by professionals. This type of key programming is called EEPROM Programming. It requires soldering skills, electronic knowledge and a lot time.
Other types of programming for car keys are a lot simpler and can be performed by the average person. They are typically done using the onboard diagnostics port, that can be accessed using a special key-fob-programming tool. This procedure can be carried out by a locksmith who is trained using an online guide or the car's owner manual.

Key Programmers
Modern vehicles typically require a key programming process to initialize the vehicle's system and allow the car to start. In some instances, the key will need to be programmed by an auto locksmith or dealer. This is because the key could not function properly or start the vehicle in any way. The reason for this is that the new key has not been programmed into the vehicle's system. This can be quite costly. It's best to have two keys that are compatible for your modern car so you can program the replacement key whenever needed.
A keyprogrammer is a device that can recode the transponder chip on a new mechanical or key fob key. It can also clone the data of an existing key to make duplicates. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software, which allows them to communicate with a computer. They also have a bidirectional user interface for working with an immobilizer system.
There are a myriad of types of keyprogrammers on the market. They are available in a variety of sizes, shapes and colors. Some keyprogrammers are cheap and others can cost thousands of dollar. Some are made for specific automobiles and provide advanced diagnostics of the vehicle's electronic system.
If you want to program an entirely new key for your vehicle, refer to the owner's manual for instructions on the procedure. Certain manufacturers employ proprietary technology that ensures the dealership is the sole entity that can create new keys, but other manufacturers make it fairly easy for anyone to do it themselves.

Transponder Chips
Transponder chips can be found in vehicles manufactured within the past 20 years. It's the tiny plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your car.
When activated by an electro-magnetic field the chip emits a low-level signal. This signal is then absorbed by the special antenna that is attached to the ignition barrel of your car. This allows the car's computer system to determine if the transponder chip inside the key is the right one for your particular car.
This stops the vehicle from starting by hot-wiring or tampering. The chip in the car key ensures that the owner is the person who owns the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are shaped like regular keys, but with an outer layer of plastic. The chip itself is housed in the plastic portion of the key, and there are a few different types of cuts on these keys: a regular standard cut laser cut (also called a sidewinder) or Ford Tibbe key.
A circuit inside the induction coil will emit a signal when the transponder is placed in the ignition barrel. The signal will be received by the chip, causing it to transmit a signal back to the car. If the car's computer detects this signal as the correct one, it will disable the immobilizer on the vehicle and allow the engine to begin.
If the car isn't able to recognize the transponder as the correct signal, it will not start the engine, and will alert you with flashing lights and an alarm. This feature is intended to deter people from trying to hack into the vehicle, however it's not a 100% security measure. A skilled and determined thief could still be able to escape this security system by using a special device to detect the signal.
It is evident that the transponder is a good option. This is something that all vehicle owners should think about if they want 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 vehicle remotely, emit chirping sounds to help locate cars, or switch on the heated steering wheel. Many of these extra features may appear convenient, but they can also make it difficult for you to keep track of your car keys.
Key fobs communicate with each other and the car using radio frequencies which are transmitted through an antenna in the middle of the key. This signal is encrypted to prevent others from stealing or stealing the signal.
Keyfobs can be programmed in a variety of ways depending on the model and brand of your vehicle. Certain models allow you to do this yourself. However, most newer models require you to visit an expert locksmith or dealer for them program a replacement key fob or additional one.
When you press the button on a key fob, the microchip sends signals to the receiver in the car that it is paired. The receiver then compares this information to the 'allowed' signals inside 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 allowed to operate.
Once the car is paired with a specific fob, it will only receive signals from that device. Other fobs won't work with the car, even if they appear like. This is to safeguard the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control of the vehicle.
The majority of newer dealerships will only accept vehicles that have original fobs, or genuine replacements sold by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security expertise which can only be obtained in the dealer's service department. Some aftermarket fobs, usually ones for older models with less sophisticated systems can be programmed with out the need for a dealership.
