Self-programming
As technology for cars has improved throughout the years, ignition keys have evolved too. The days of simple mechanical-only keys that were made at the hardware store for less than $10. Modern models come with computers that are enhanced anti-theft protection. These cars require a transponder-chip-integrated key to be programmed by a professional locksmith mechanic or dealer in order to function properly.
There are a few different types of car keys programming that can be done by professional locksmiths. Certain types are more complex and require advanced tools. These tools are not generally accessible to the general public and are used only by professionals. This kind of programming is known as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot time.

These are done with the onboard diagnostic port, which can be accessed via a tool specifically designed for key-fob programming.

You can be certain that the new key will function and is programmable for your vehicle. You'll have to pay the dealer for programming and replacement keys if you don't.
Key Programmers
Modern cars require a key-programming process to initialize their vehicle's systems and start the car. In some instances, the key must be configured by the dealer or an auto locksmith. The key may not work correctly or will not start the vehicle in any way. This is because the key hasn't yet been programmed into the vehicle's system. This can be expensive. It is recommended to have two keys that work for your modern car so you can program the replacement key when needed.
A keyprogrammer can recode the transponder chip of the new mechanical key or key fob. It also can clone information from an existing key to make duplicates. These are handheld devices connected to a 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 for working with an immobilizer system.
There are a myriad of types of keyprogrammers available on the market. They are available in a variety of shapes, sizes and colors. Some are cheap while others are advanced and could cost thousands of dollars. Some are made for specific vehicles and can provide advanced diagnostics of the vehicle's electronic system.

They are less expensive than going to a dealership however, they aren't expensive. Make sure you investigate the seller prior to purchasing one. Some aren't reliable and can damage your car.
Transponder Chips
If your car is made in the last 20 years, it is likely that it has a transponder chip inside of it. It's a tiny plastic piece inside the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
When it is activated by an electromagnetic field the chip emits a low-frequency signal. This signal is then taken up by the antenna that is fitted around the ignition barrel of your car. This allows the car's computer system to verify that the transponder chip inside the key is the correct one for your specific vehicle.
This prevents the vehicle from starting by hot-wiring, or by manipulating. The chip inside the key also verifies that you are the genuine owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Regular transponder keys are shaped like regular metal keys with a plastic top. The chip itself is housed within the plastic part of the key and there are a few different types of cuts on these keys: a regular cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal will be absorbed by the chip, causing it to transmit a signal to the car. If the computer on the car recognizes this signal as the correct one, it will disable 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 starting and will alert you by flashing its lights and sounding an alarm. This feature is designed to discourage people from trying to tamper with the vehicle, but it's not a 100% security measure. A skilled and skilled criminal could still bypass this system with a specially designed device that blocks the signal.
It is evident that the transponder is an excellent option. This is something that all car owners should think about if they want to protect their investment and minimize the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making noises to aid in finding a car in a parking lot, today's key fobs can also turn on a heated steering wheel, or roll down all windows with a single push. These additional features can make it difficult to find your car keys.
Key fobs communicate with each other and with the car through radio frequencies that are transmitted via a small antenna located in the middle of the key. The transmission is encrypted, which helps to keep others from stealing and re-transmitting the signal.
There are several ways to program a key fob depending on the vehicle's make and model. Some cars allow you to do it yourself. However, the majority of modern models require you to visit a professional locksmith or dealer to program a new key fob or an additional one.
When you press the button on your key fob the microchip inside sends a code to the car's receiver it is paired with. The receiver then compares this information to the signals that are allowed inside the fob, and either opens or locks the door. If the data does not match, the car will not be allowed to drive.
Once the car is linked with a specific fob, it will only receive signals from that specific device. As a result, other fobs will not work with the vehicle even if they have the same appearance. This safeguards the integrity of the computer system that runs the car and blocks unauthorized key fobs gaining control over it.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. It is because the only place that has the knowledge to create the replacement fob is a dealer's service department. However, some aftermarket fobs typically for older models that have less sophisticated systems -- can be programmed by consumers without the need for a dealership.
