Newer models are equipped with computers that are enhanced anti-theft protection. In order to work correctly, these vehicles require a transponder chip-integrated key be programmed into the vehicle by a professional locksmith or mechanic/car dealer.
There are several types of car keys programming that can be performed by professional locksmiths. Certain are complicated and require specialized tools. These tools are usually not available to the general public and are used only by professionals. This kind of key programming is called EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot time.
Other forms of programming car key s are a lot simpler and can be done by the average person. They are typically done using the onboard diagnostics port, that can be accessed using a special key-fob-programming tool.

Key Programmers
Modern automobiles require a key-programming procedure to set up their systems and then start the vehicle. In some instances the key needs to be programmed by an auto locksmith or dealer. The key might not function properly or not start the car at all. This is because the key has not yet been programmed into the vehicle's system. This can be expensive. This is why it's a great idea to always have two keys working for modern vehicles and to have the replacement key programmed when required.
Keyprogrammers can recode a transponder chip on an entirely new mechanical key or key fob. It is also able to copy the information from an existing key, allowing duplicates to be created. These devices are handheld units 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 interface to work with an immobilizer system.
There are many different types of keyprogrammers that are available on the market. They are available in a variety of sizes, shapes, and colors.

Transponder Chips
Transponder chips are likely be found in cars that were manufactured within the last 20 years. It's the small plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
When it is activated by an electromagnetic field, the chip emits a low-frequency signal. The signal is taken up by an 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 the car you have.
This is what stops from modifying or hot-wiring the ignition system of the vehicle to turn it on. The chip inside the key also confirms that you are the legitimate owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys that are regular in shape like regular keys, but with an outer layer of plastic. The chip is inside the plastic portion of the keys. There are a variety of cuts: a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe), and the Ford Tibbe.
The circuit in the induction coil emits an electrical signal when the transponder is placed in the ignition barrel. The signal is absorbed by the chip, which then transmits 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 start.
If the car isn't able to recognize the transponder as a valid signal, it won't 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 isn't an unbreakable security measure. A skilled and determined criminal may still be able to escape this security system by using a special device to take over the signal.
You can see that a transponder is a great option. This is something that all vehicle owners should think about if they want to safeguard their investment and minimize the risk of theft.
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 lot keys of today can also activate a heated steering wheel, or roll down all of the windows with just a single push. These additional features can make it difficult for you to find your car keys.
Key fobs communicate with each other and the car using radio frequencies which are transmitted by an antenna that is located in the center of the key. The transmission is encrypted, which helps prevent others from intercepting and retransmitting the signal.
You can program a keyfob in various ways based on the model and brand of your car. It is possible to do this yourself, however most modern automobiles require a locksmith shop or a professional to program a replacement or an additional fob.
When you press the button on your key fob, the microchip inside transmits a code to the car's receiver it is paired with. The receiver then compares the data with the 'allowed signals' that are stored in the key fob, and then opens or locks the car door. If the data does not match the fob's information, the car won't be allowed to operate.
Once the car is associated with a particular fob, it can only receive signals from that device. This means that other fobs won't be able to work with the vehicle even though they have the same appearance. This ensures the security of the computer system of the vehicle and stops unauthorized key fobs gaining control of it.
Most dealerships with newer cars will only accept vehicles that have original fobs or genuine replacements offered by the manufacturer. This is because the only place with the expertise to prepare an appropriate replacement fob is a dealer's service department. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems -- can be programmed by customers without the need for dealers.
