Self-Programming
The ignition keys have evolved along with the car technology. Gone are the days of simple mechanical keys that were made at a hardware store for under $10. Modern models come with computers that are enhanced security against theft. In order to work properly, these cars require that a transponder chip-integrated key be programmed into the vehicle by a certified locksmith or a car dealer/mechanic.
Professional locksmiths are able to perform various types of programming for keys for cars. Some are complex and require specialized tools. These tools aren't usually accessible to the general public and are only used by professionals. This kind of programming is known as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot of time.
Other kinds of programming for car keys are much easier and can be done by the average person. These are usually done by using the diagnostics port on the car, that can be accessed using the key-fob-programming device. This method can be done by a trained locksmith with the help of an online guide or the car's owner manual.

Key Programmers
Modern automobiles require a key-programming method to set up their systems and then start the vehicle. In a number of cases keys must be configured by the dealer or auto locksmith. This is because the key could not function correctly or start the vehicle at all. This is because the key has not yet been programmed into the vehicle's system. This can be costly. It is best to have two keys that work with your current car so you can program the replacement key if required.
A keyprogrammer can reprogram a transponder chip on the new mechanical key or key fob. It can also clone the data of an existing key in order to create duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that allows them to communicate with computers. They also have a bidirectional interface that works with an immobilizer system.
There are a variety of keyprogrammers on the market. They are available in a variety of shapes, sizes and colors. Some keyprogrammers are cheap and others may cost thousands of dollars. Certain models are specifically designed for certain types of cars and can offer advanced diagnostics for the vehicle's electronic systems.

Transponder Chips
Transponder chips are likely to be found in cars manufactured within the past 20 years. It's a small plastic thing in the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
When activated by an electro-magnetic field the chip emits a low-level signal. The 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 right one for your specific vehicle.
reprogram car key is the reason why from modifying or hot-wiring the ignition system of your vehicle to start it. The chip inside the key ensures that the owner is the person who owns the vehicle. This can help to reduce car theft.
Transponder keys appear like regular keys made of metal but they have a plastic cap. The chip is contained in the plastic portion of the key and there are different kinds of cuts available on the keys: a 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 placed in the the ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the onboard car computer detects this signal as the right one, it will shut down the vehicle's immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder as the correct signal, it will not start the engine, and will alert you with flashing lights and an alarm. This function is designed to discourage those who would attempt to alter the vehicle. However it's not an absolute security measure. A skilled and determined thief may still be able to get around this system using a device that can intercept the signal.
As you can see there are quite few advantages to getting transponder keys. This is something that all car owners should consider if want to safeguard their investment and decrease the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making chirping sounds to help find the car in a parking lot keys of today can also switch on a heated steering wheel, or roll down all of the windows with a single push. Many of these extra features may appear convenient but they could make it difficult for you to keep track of your car keys.
Key fobs use radio frequencies to communicate with each other and with the car. The frequencies are transmitted through a small antenna located inside the middle of the key. The communication is encrypted, which helps prevent others from intercepting and replicating the signal.
You can program a keyfob in different ways based on the model and make of your vehicle. Certain cars let you do it yourself. However, the majority of modern models require you to visit an expert locksmith or dealer for them program a replacement key fob or additional one.
When you hit the button on a key fob the microchip inside sends an encoded code to the car's receiver it is paired with. programming car key compares this information to the 'allowed' signals on the fob and either opens or locks the door. If the information isn't in line an chirping sound is heard and the car isn't able to operate.
Once the car is linked with a particular fob, it will only accept signals from that specific device. Other fobs will not work with the car, even if they appear similar. This ensures the security of the computer system of the car and blocks the use of unauthorized key fobs to gain control over it.
Most newer car dealers will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security skills that can only be found in the dealer's service department. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems -- can be programmed by the consumer without the need of a dealership.
