Self Programming
The ignition keys have developed in tandem with the advancements in car technology. Gone are the days of simple mechanical keys that could be manufactured at the hardware store for less than $10. The latest models are equipped with computer systems that are more secure against theft. The 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 kinds 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 used only by professionals. This type of programming is known as EEPROM Programming. It requires soldering skills, electronic knowledge and a significant amount of time.
Other kinds of key programming can be done by anyone. They are typically done using the onboard diagnostics port that can be accessed using the key-fob-programming device. Locksmiths can carry out this method with the help of a guide online and the owner's manual.

Key Programmers
Modern automobiles require a key-programming method to start the vehicle's system and start the car. In some cases the key will have to be programmed by an auto locksmith or a dealer. The key might not function properly or not start the vehicle in any way. This is because the key has not yet been programmed into the vehicle's system. This can be expensive. This is why it's a great idea to always have two keys that work for modern vehicles and to have the replacement key programmed when required.
A keyprogrammer is a device that recodes the transponder chip in a new key fob or mechanical key. It is also able to copy information from an existing key to create duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They come with diagnostic software that enables them to communicate with computers and also provide bidirectional interfaces to work with the immobilizer system.
There are a variety of keyprogrammers available on the market. They are available in a variety of sizes, shapes and colors. Certain keyprogrammers are affordable and others may cost thousands of dollars. Some are specifically designed for certain types of vehicles and can provide advanced diagnostics for your car's electronic systems.

Transponder Chips
Transponder chips are likely to be found in vehicles manufactured within the past 20 years. It's a small plastic thing on the back of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
When it is activated by an electro-magnetic field the chip emits a low-level signal. The signal is absorbed by a special antenna attached to the ignition barrel. This allows the car's computer system to determine if the transponder chip that is in the key is the right one for your specific vehicle.
This stops the vehicle from being started by either hot-wiring or by tampering. The chip in the car key confirms that the owner is the one who owns the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys appear like regular keys made of metal but they have caps made of plastic. The chip is located inside the plastic part of the keys. There are several different cuts: a standard cut, laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is received by the chip which sends a signal to the vehicle. If the computer inside the car detects the signal as valid it will turn off the vehicle immobilizer so that the engine can start.
If the vehicle does not recognize the transponder signal as the right one, it will prevent the engine from running and will alert you by flashing its lights and sounding an alarm. This feature is designed to discourage people from tampering with the vehicle. However, it is not an unbreakable security measure. A skilled and determined criminal may still be able to bypass this system by using a special device to detect the signal.
As you can see there are quite few advantages to getting a transponder key. All car owners must take this into consideration when they want to safeguard their investment and decrease the risk of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. automotive key programming can also start your vehicle remotely, make chirping noises to help locate the car or turn on the heated steering wheel. Many of these extra features may seem convenient, but they can also make it difficult for you to keep the keys to your car.
Key fobs communicate with one other and the car using radio frequencies that are transmitted through an antenna that is located in the center of the key. The communication is encrypted, which helps to prevent others from intercepting and re-transmitting the signal.
You can program a keyfob in different ways based on the make and model of your vehicle. Certain cars let you do it yourself. However, the majority of modern models require you to visit a professional 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. The receiver compared this information to the 'allowed' signals stored in the fob and then either locks or opens the door. If the data doesn't match an chirping sound is heard and the car isn't permitted to function.
Once the car is linked with a specific fob it will only receive signals from that specific device. This means that other fobs won't work with the vehicle even if they look the same. This protects the integrity of the car's computer system and to prevent the use of unauthorized key fobs to gain control over the vehicle.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security expertise which can only be obtained in the dealer's service department. However, reprogram car key from the aftermarket -- usually those for older models that have less sophisticated systems -- can be programmed by consumers without the need of an authorized dealer.
