Self-programming
As car technology has evolved throughout the years, ignition keys have evolved too. There are no more simple mechanical keys that were made at the hardware store for less than $10. Newer models are equipped with computers that offer improved security against theft. To function correctly, these vehicles require that a transponder chip-integrated key be programmed to the vehicle by a certified locksmith or car dealer/mechanic.
Professional locksmiths can carry out a variety of different types of programming for car keys. Some are complex and require specialized tools. These tools are usually not available to the general public and are only used by professionals. This kind of programming is known as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot time.
Other kinds of key programming can be carried out by anyone. They are typically done using the onboard diagnostics port that can be accessed using a special key-fob-programming tool. Locksmiths can carry out this method with the help of a guide online and the owner's manual.

Key Programmers
Modern vehicles require a key-programming method to start the vehicle's system and start the car. In some instances the key needs to be configured by the auto locksmith or dealer. This is because the key could not function correctly or start the car at all. This is because the key hasn't yet been programmed into the vehicle's system. This can be costly. It is best to have two keys that work for the modern automobile so that you can program the replacement key when required.
A keyprogrammer can reprogram the transponder chip of an entirely new mechanical key or key fob. It is also able to copy the information from an existing key and allow duplicate keys to be created. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that enables them to communicate with the computer, and they also have bidirectional interfaces to work with the immobilizer system.
There are a number of different kinds of keyprogrammers that are available and they come in a variety of sizes and shapes. Some are inexpensive, while others are very advanced and can cost thousands of dollars. Certain models are specifically designed for certain types of cars and can provide advanced diagnostics for your car's electronic systems.

They're less expensive than going to the dealership however, they're not cheap. Be sure to look up the seller before buying one - some are not reliable and can damage your vehicle.
Transponder Chips
Transponder chips are likely be found in vehicles manufactured within the past 20 years. It's a small piece of plastic inside the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
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 positioned around the ignition barrel of your car. The computer system of the vehicle will then confirm that the chip in the key's transponder is the right one for your car.
This stops the vehicle from being started by hot-wiring, or by manipulating. The chip inside the key also verifies that you are the legitimate owner of the vehicle. This can reduce car theft.
Transponder keys appear like regular metal keys, but with a plastic cap. The chip is inside the plastic part of the keys. There are a variety of cuts that are a standard cut, laser cut (also called a sidewinder or Ford Tibbe), and the Ford Tibbe.
A circuit inside the induction coil emits signals 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 computer inside the car detects the signal as correct it will turn off the vehicle immobilizer to allow the engine start.
If the vehicle does not recognize the transponder signal as being the correct one, it will stop the engine from starting and will notify you by flashing its lights and sounding a siren. 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 could still be able to get around this system using a special device to take over the signal.
You can see that the transponder is an excellent option. All car owners should consider this if they wish to protect their investment and minimize theft risk.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also start your vehicle from a distance, make chirping sounds to aid in finding a car, or switch on the heated steering wheel. These extra features can make it difficult to find your car keys.
Key fobs communicate with each other and with the car through radio frequencies which are transmitted by an antenna that is located in the middle of the key. This communication is encrypted to block other key fobs from stealing or modifying the signal.
There are a few different ways to program a key fob, based on your vehicle's model and make. It is possible to do this yourself, but the majority of newer vehicles require an expert locksmith or dealer to program a replacement or additional fob.
When you press the button on a key fob the microchip transmits signals to the receiver inside the vehicle with which it is linked. The receiver then compares the data with the 'allowed signals' stored in the key fob, and then locks or opens the car's doors. If the data does not match the fob's information, the car won't be allowed to run.
When a car is connected with a specific fob, it will only receive signals from that device. Other fobs won't work with the car, despite the fact that they look like. This is to safeguard the integrity of the car's computer system and prevent unauthorized key fobs from gaining control of the vehicle.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. It is because the only place with the expertise to prepare a replacement fob is in the service department of the dealer. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
