The ignition keys have changed in tandem with the advancements in car technology. Gone are the days of simple mechanical keys that could be manufactured at an hardware store for less than $10. The newer models have computers that have improved anti-theft security. The cars require a transponder chip-integrated key to be programmed by a professional locksmith car dealer or mechanic to function properly.
Professional locksmiths can carry out a variety of different types of programming for keys to cars. Certain types are extremely complex and may require advanced tools. These tools are generally not available to the general public and are only used by professionals. This kind of key programming is called EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time.
Other types of car key programming are much easier and can be accomplished by anyone who is able to. They can be done by using the onboard diagnosis port, which can be accessed via a tool specifically designed for key fob programming.

Key Programmers
Modern cars typically require a key programming procedure to set up the car's system and allow the vehicle to begin. In a number of cases the key needs to be configured by the dealer or an auto locksmith. The key may not work properly or it may not even start the car in any way. This is because the key has not yet been programmed into the vehicle's system. This can be costly. This is why it's a good idea to always have two keys that work for a modern automobile and to have the replacement key programmed if necessary.
A keyprogrammer is a device which can reprogram the transponder chip on the form of a new mechanical or key fob key. reprogram key fob is also able to copy the information from an existing key, allowing duplicates to be made. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They come with diagnostic software that allows them to communicate with computers and also provide an interface that works bidirectionally with the immobilizer system.
There are many different types of keyprogrammers available on the market and they come in all shapes and sizes. Certain keyprogrammers are affordable, while others may cost thousands of dollars.

Transponder Chips
Transponder chips are likely be found in cars that were manufactured within the last 20 years. It's the tiny plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal is then absorbed by the special antenna that is attached to the ignition barrel of your car. This allows the computer in your vehicle system to verify that the transponder chip that is in the key is the right one for your particular car.
This is what prevents doing hot-wiring or altering the ignition system of the vehicle to turn it on. The chip inside the key verifies that the owner is the person who is the owner of the vehicle. This helps to prevent car theft.
Transponder keys resemble regular metal keys, but with a plastic cap. The chip itself is housed in the plastic portion of the key, and there are different cuts that can be found on the keys: a cut laser cut (also called a sidewinder key) or Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out a signal. The signal is received by the chip which then transmits a signal to the vehicle. If the computer onboard the car recognizes the signal as valid, it will disable vehicle 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 will warn you with flashing lights and siren. This feature is designed to discourage those who would attempt to alter the vehicle. However, it is not an absolute security measure. A determined and skilled thief could still evade this system using a special device that detects the signal.
As you can see there are quite number of advantages to having transponder keys. Every car owner should take this into consideration in order to safeguard their investment and decrease theft risk.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making sound chirps to help locate the car in a parking space keys of today can also turn on a heated steering wheel or open all windows with a single press. Many of these extra features may seem convenient, but they can also make it harder for you to keep the track of your car keys.
Key fobs communicate with each other and the car using radio frequencies that are transmitted by an antenna that is located in the center of the key. This communication is encrypted, which helps to prevent others from intercepting and replicating the signal.
There are many ways to program a key fob based on your vehicle's make and model. You may be able to do it yourself, but most newer automobiles require a locksmith shop or a professional to program a replacement or an additional fob.
When you press the button on your key fob the microchip inside sends an encoded code to the car's receiver that it is paired with. The receiver then compares this information to the 'allowed' signals stored in the fob and then either opens or locks the door. If the information doesn't match the signals, the car will not be allowed to drive.
Once the car is paired with a specific fob, it will only receive signals from the device that is associated with it. Other fobs won't work with the car, even though they appear like. This ensures the security of the computer system that runs the car and blocks unauthorized key fobs gaining control of 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 experience to design the replacement fob is the service department of a dealer. 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 for a dealership.
