Self-programming
The ignition keys have evolved in tandem with the advancements in car technology. The days of simple mechanical-only keys that were made at a hardware store for under $10. The latest models are equipped with computers that have improved anti-theft security. These cars require a transponder-chip-integrated key to be programmed by a professional locksmith, car dealer or mechanic for proper operation.
There are several types of car keys programming that can be performed by professional locksmiths. Certain types are extremely complex and may require sophisticated tools. These tools are generally not accessible to the general public and are only used by professionals. This type of programming is known as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time.
Other forms of programming for car keys are much easier and can be done by anyone who is able to. They are typically done using the onboard diagnostics port, which can be accessed with a special key-fob-programming tool. Locksmiths can execute this procedure with the help of an online guide as well as the owner's manual.

Key Programmers
Modern cars frequently require a key programming process to set up the car's system and allow the vehicle to begin. In some cases, the key will need to be programmed by an auto locksmith or dealer. The key may not work correctly or will not start the car at all. The reason is because the new key hasn't been programmed to the car's system - and this can be very costly. This is why it's a great idea to always have two keys working for modern vehicles and to have the replacement key programmed if required.
A keyprogrammer can recode the transponder chip of the new mechanical key or key fob. It is also able to copy data from 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 that allows them to communicate with computers. They also have a bidirectional user interface for working with an immobilizer system.
There are many different types of keyprogrammers available that are available and they come in all sizes and shapes. Some are inexpensive and others are advanced and could cost thousands of dollars. Certain models are specifically designed for automobiles and offer advanced diagnostics of the vehicle's electronic system.

Certain manufacturers have proprietary technology that ensures the dealership is the sole entity that can make new keys, but other manufacturers make it easy for anyone to do it themselves.

Transponder Chips
Transponder chips can be found in cars that were manufactured within the past 20 years. It's a tiny plastic thing inside the head of your key that contains an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is absorbed by a special antenna that is attached to the ignition barrel. The computer system in the vehicle will then confirm that the transponder chip of the key is the right one for your vehicle.
This is what stops hot-wiring or tampering with the ignition system of your vehicle to get it started. The chip inside the key also confirms that you are the genuine owner of the vehicle. This will help reduce car theft.
Transponder keys resemble normal keys, but with caps made of plastic. The chip is housed in the plastic portion of the key and there are a few different types of cuts on the keys: a standard cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.
The circuit in the induction coil will emit a signal when the transponder is inserted into an ignition barrel. The signal is taken up by the chip, which sends a signal to the vehicle. If the car's computer recognizes this signal as being the correct one, it will shut down the vehicle immobilizer and allow the engine to start.
If the car does not recognize the transponder signal as being the correct one, it will keep the engine from running and will alert you by flashing its lights and sounding a siren. 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 could still be able to bypass this system by employing a device designed to intercept the signal.
As you can see there are quite number of benefits to having transponder keys. All car owners should take this into consideration in order to safeguard their investment and decrease theft risk.
Key Fobs
Key fobs today can do more than just lock and unlock doors. They can also start your car remotely, emit chirping sounds to aid in finding the car or turn on the heated steering wheel. Many of these extra features might seem useful, but they can also make it more difficult to keep track of your car keys.
Key fobs communicate with one with the car via radio frequencies that are transmitted via a small antenna located in the center of the key. The communication is encrypted, which helps prevent others from intercepting and retransmitting the signal.
There are a few different ways to program a key fob based on the vehicle's make and model. Certain models allow you to do this by yourself. However, the majority of modern models require you to visit an expert locksmith or dealer in order to program a replacement key fob or additional one.
When you hit the button on a key fob, the microchip inside transmits an encoded code to the car's receiver that it is paired with. The receiver compared this information with the 'allowed' signals inside the fob, and either locks or opens the door. If the data doesn't match, a chirping sound is heard and the car isn't able to operate.
Once the car is paired with a particular fob, it will only accept signals from that specific device. In turn, other fobs will not work with the vehicle even though they appear similar. This protects the integrity of the computer system in the vehicle and stops unauthorised key fobs from taking control of it.
Most dealerships with newer cars will only deal with cars with original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security expertise that is only available in the dealer's service department. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems -- can be programmed by customers without the need of dealers.
