Self Programming
The ignition keys have changed along with the car technology. The days of simple mechanical keys that you could purchase from a hardware store for less than $10 have gone. The latest models are equipped with computers with improved anti-theft protection. The cars require a transponder chip-integrated key to be programmed by a professional locksmith mechanic or dealer in order to function properly.
Professional locksmiths can perform various types of programming for car keys. Certain types are extremely complex and require sophisticated tools. These tools are not available to the general public and are used only by professionals. This type of programming is known as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a significant amount of time.
Other kinds of key programming can be performed by anyone. They are accomplished using the onboard diagnostic port, which can be accessed via a tool specifically designed for key fob programming.

You can be sure the new key works and is compatible with your vehicle. You'll have to pay the dealer for programming and replacement keys if they don't.
Key Programmers
Modern vehicles require a key-programming procedure to set up their systems and then start the vehicle. In some instances the key will have to be programmed by an auto locksmith or a dealer. The key may not work correctly or will not start the vehicle at all. This is because the new key has not been programmed into the vehicle's system - and this can be very costly. It is recommended to have two keys that work for the modern automobile so that you can program the replacement key when required.
Keyprogrammers are devices which can reprogram the transponder chip into an entirely new mechanical or key fob key. It is also able to copy the data from an existing key, allowing duplicates to be made. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They have diagnostic software that allows them to communicate with the computer as well as a bidirectional interface for working with the immobilizer system.
There are many different types of keyprogrammers available that are available and they come in a variety of sizes and shapes.

Some aren't reliable and may damage your vehicle.
Transponder Chips
Transponder chips can be found in vehicles manufactured within the past 20 years. It's a tiny plastic piece on the back of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal is then absorbed by a special antenna that is attached to the ignition barrel. This allows the computer in your vehicle system to verify that the transponder chip in the key is the correct one for the car you have.
This is what stops hot-wiring or tampering with the ignition system of your vehicle to start it. The chip inside the key also confirms that you are the legitimate owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.
Transponder keys look like regular keys made of metal but they have caps made of plastic. The chip is contained within the plastic part of the keys. There are a variety of cuts that are a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe.
The circuit in the induction coil will emit a signal when the transponder is put into the ignition barrel. The signal is received 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 turn off the vehicle's immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder signal as the proper one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This feature is designed to discourage people from trying to tamper with the vehicle, however it is not a foolproof security measure. A skilled and skilled criminal can still get around this system with a specially designed device that intercepts the signal.
You can see that the transponder is a good option. This is something that all vehicle owners should consider if they are looking to safeguard their investment and reduce the risk of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also turn on the car remotely, make chirping noises to help locate a car or turn on the heated steering wheel. Many of these extra features may appear convenient however they could make it more difficult to keep the keys to your car.
Key fobs use radio frequencies to connect with one another and the car. These frequencies are sent through a small antenna located in the middle of the key. The communication is encrypted, which helps to prevent others from intercepting and retransmitting the signal.
You can program a keyfob in different ways based on the model and brand of your car. Certain cars let you do it yourself. However, most newer models require you to visit an expert locksmith or dealer in order to program a replacement key fob, or an alternative one.
When you press the button on a key fob, the microchip sends an indication 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 locks or opens the car's doors. If the information doesn't match, a chirping sound is heard and the car isn't permitted to operate.
Once the car has been associated with a particular fob, it only accepts signals from the device. This means that other fobs won't be able to work with the vehicle, even though they have the same appearance. This protects the integrity of the computer system in the car and blocks unauthorized key fobs gaining control over it.
Most newer car dealerships will only work with cars with original fobs, or genuine replacements sold by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security expertise which can only be obtained in the dealer's service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems -- can be programmed by customers without the need of an authorized dealer.
