Self Programming
As the technology of cars has advanced over the years, the ignition keys have also evolved too. There are no more simple mechanical-only keys that were made at an hardware store for less than $10. The latest models come with computers that have improved anti-theft security. These cars require a transponder-chip integrated key to be programmed by a professional locksmith, mechanic or dealer for proper operation.
There are many types of car key programming that can be done by locksmiths who are professionals. Certain types are extremely complex and may require sophisticated tools. These tools are not generally accessible to the general public and are utilized only by professionals. This type of programming is known as EEPROM Programming. It requires the ability to solder, electronic skills and a lot time.
Other types of key programming can be performed by anyone. These are done using the onboard diagnostic port, which can be accessed via a tool specifically designed for key-fob programming. A locksmith can perform this method with the assistance of a guide online and the owner's manual.

This way, you will be sure that the new key is programmed for your vehicle and that it works. You'll have to pay the dealer for programming and replacement keys if you do not.
Key Programmers
Modern vehicles require a key-programming procedure to start the vehicle's system and to start the car. In many cases, the key must be set up by the dealer or auto locksmith. The key may not work properly or it may not even start the car in any way. This is because the key hasn't yet been programmed into the car's system. This can be costly. This is why it's a good idea to always have two keys that work for a modern car and have the replacement key programmed when needed.
A keyprogrammer can recode the transponder chip on an entirely new mechanical key or key fob. It is also able to clone information from an existing key and allow duplicate keys to be made. Recommended Looking at are handheld devices that connect to a car's On Board Diagnostics (OBD port). They come with diagnostic software, which allows them to communicate with computers. They also feature a bidirectional user interface for working with an immobilizer system.
There are a myriad of types of keyprogrammers that are available on the market. They come in all sizes, shapes and colors. Certain keyprogrammers are affordable and others may cost thousands of dollars. Some are made for specific vehicles and can provide advanced diagnostics of the vehicle's electronic system.
Consult your owner's guide to learn how to program the key to your vehicle. Some manufacturers use proprietary technology that ensures the dealership is the only entity that can create new keys, but other manufacturers make it easy for anyone to do it themselves.

They're less expensive than visiting a dealer, but still not expensive. Be sure to research the seller before purchasing one. Some aren't reliable and could damage your vehicle.
Transponder Chips
If your car is made within the last 20 years, then it has a transponder inside of it. It's the small piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
When it is activated by an electro-magnetic field the chip emits a low-frequency signal. This signal is then received by a specific antenna attached to the barrel of ignition. The computer system in the vehicle will then confirm that the transponder chip of the key is the correct one for your car.
This prevents the vehicle from being started through hot-wiring, or by altering the key. The chip inside the key confirms that the owner is the person who owns the vehicle. This helps to prevent car theft.
Regular transponder keys are shaped like regular keys and have a plastic top. The chip is located inside the plastic part of these keys. There are several different cuts: a standard cut, laser cut (also known as a sidewinder or Ford Tibbe), and a Ford Tibbe.
The circuit in the induction coil emits signals when the transponder is inserted into the ignition barrel. The signal will then get absorbed by the chip, causing it to send a signal back to the car. If the computer in the car recognizes the signal as being correct it will turn off the car immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder as being the proper signal, it won't start the engine and alert you with flashing lights and an alarm. This function is designed to discourage those who would attempt to alter the vehicle. However it isn't an unbreakable security measure. A skilled and determined thief could still bypass this system by using a specific device that blocks the signal.
It is evident that the transponder is an excellent option. Every car owner must take this into consideration in order to safeguard their investment and minimize theft risk.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also turn on the vehicle remotely, make chirping noises to aid in finding cars, or turn on the heated steering wheel. These extra features could make it difficult to locate your car keys.
Key fobs use radio frequencies to connect with one another and the car. The frequencies are transmitted through a small antenna located within the middle of the key. The communication is encrypted, which helps stop others from stealing and retransmitting the signal.
There are many ways to program a key fob, based on your vehicle's model and make. Certain cars let you do this by yourself. However, the majority of modern models require you to visit a professional locksmith or dealer to program a replacement key fob or additional one.
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 then compares the data with the 'allowed signals' that are stored in the key fob and then it opens or closes the car's doors. If the information doesn't match the signals, the car will not be allowed to drive.
After the car has been associated with a particular fob, it will only accept signals from the device. Other fobs won't work with the car, even though they look identical. This is to safeguard the integrity of the car's computer system and prevent unauthorised key fobs from taking control over the vehicle.
Most dealerships with newer cars will only work with cars with original fobs, or genuine replacements offered by the manufacturer. This is because the process of creating a replacement fob requires technological and security skills that can only be found in the dealer service department. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems -- can be programmed by consumers without the need of a dealership.
