Professional locksmiths are able to perform various types of programming for car keys. Some are complex and require advanced tools. These tools are not accessible to the general public and are only used by professionals. This type of key programming is called EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time.
Other kinds of programming car keys are much simpler and can be accomplished by anyone who is able to. These are usually done by using the onboard diagnostics port that can be accessed using the key-fob-programming device. Locksmiths can carry out this method with the assistance of a guide online and the owner's manual.

A keyprogrammer can reprogram the transponder chip on a new mechanical key or key fob. It is also able to copy the information from an existing key, allowing duplicates to be created. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They have diagnostic software that allows them to communicate with the computer, and they also have an interface that works bidirectionally with the immobilizer system.
There are a myriad of types of keyprogrammers that are available on the market. They are available in a variety of sizes, shapes, and colors.

Transponder Chips
If your car was built within the last 20 years, then it has a transponder inside of it. This is a little piece of plastic in the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.
When it is activated by an electro-magnetic field the chip emits a low-frequency signal. The signal is received by a specific antenna attached to the barrel of ignition. This allows the computer in your vehicle system to verify that the transponder chip inside the key is the correct one for your particular car.
This prevents the vehicle from starting by hot-wiring or manipulating. The chip in the car key verifies that the owner is the one who is the owner of the vehicle. This will help reduce car theft.
Transponder keys look like regular metal keys, but with caps made of plastic. The chip is contained within the plastic portion of the keys. There are several different cuts that are a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe) and the Ford Tibbe.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer on the car detects this signal as the correct one, it will turn off the immobilizer on the vehicle and allow the engine to start.
If the car isn't able to recognize the transponder as the correct signal, it won't start the engine and notify you via flashing lights and an alarm. This feature is designed to discourage people from trying to hack into the vehicle, but it is not a foolproof security measure. A skilled and determined criminal may still be able to get around this system using a special device to intercept the signal.
It is evident that a transponder is a great option. All car owners must take this into consideration if they wish to protect their investment and minimize theft risk.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making noises to aid in finding the car in a parking space Key fobs today can also switch on a heated steering wheel or open all windows with a single button click. These additional features can make it difficult to locate your car keys.
Key fobs utilize radio frequencies to communicate with each other and with the car. These frequencies are transmitted via a small antenna that is located inside the middle of the key. This communication is encrypted, which helps to keep others from stealing and replicating the signal.
You can program a keyfob in various ways based on the model and make of your vehicle. You may be able to do it yourself, but most newer cars require that you visit 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 transmits a signal to the receiver inside the car with which it is linked. The receiver compares the information with the permitted signals stored in the key fob, and then locks or opens the car door. If the information 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 accept signals from the device. Other fobs will not work with the car, despite the fact that they look similar. This ensures the security of the computer system in the vehicle and stops 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 preparing a replacement fob requires technological and security knowledge that is only available in the dealer service department. Some aftermarket fobs, usually ones for older models that have less sophisticated systems can be programmed without the need for a dealership.
