Self-programming
As the technology of cars has advanced over the years, the ignition keys have also evolved as well. Gone are the days of simple mechanical keys that could be made at the hardware store for less than $10. 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, car dealer or mechanic in order to function properly.
There are a few different kinds of car key programming that can be done by professional locksmiths. Some are very complex and may require sophisticated tools. These tools aren't usually available to the public and are used only by professionals. This kind of programming is known as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot time.
Other kinds of programming for car keys are much simpler and can be done by anyone who is able to. They can be done by with the onboard diagnostic port, which can be accessed with a special tool for key fob programming. This method can be performed by a locksmith who is trained with the help of an online guide or the car's owner manual.

This way, you can be sure that the new key has been programmed to your vehicle and that it will work. If not, you'll have to pay the dealer for replacement keys and programming services.
Key Programmers
Modern automobiles require a key-programming procedure to set up their systems and to start the car. In certain instances the key will have to be programmed by an auto locksmith or a dealer. The key may not function properly or it may not even start the vehicle in any way. The reason is because the new key hasn't been programmed to the car's system, and this could be quite costly. It is best to have two keys that are compatible for your modern car so you can program the replacement key whenever needed.
A keyprogrammer is a tool which can reprogram the transponder chip on the form of a new key fob or mechanical key. It can also clone the data of an existing key and allow duplicate keys to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that allows them to communicate with the computer and also provide a bidirectional interface for working with the immobilizer system.
There are many different types of keyprogrammers that are available on the market. They come in all shapes, sizes and colors. Some keyprogrammers are cheap and others can cost thousands of dollar. Some are specifically designed for certain types of cars and provide advanced diagnostics for the car's electronic systems.
If you're looking to program a new key to your vehicle, consult the owner's manual to find out how to do it. Some manufacturers use proprietary technology that makes sure that the dealership is the only entity able to create new keys. However, other manufacturers make it easy for anyone to do it themselves.

Transponder Chips
Transponder chips can be found in cars manufactured within the past 20 years. This is the little plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.
When activated by an electro-magnetic field the chip emits a low-frequency signal. This signal is then absorbed by a special antenna attached to the ignition barrel. This allows the car's computer system to determine if the transponder chip in the key is the right one for the car you have.
This is what prevents doing hot-wiring or altering the vehicle's ignition system to turn it on. The chip in the key also confirms that you are the legal owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys appear like normal keys but they have a plastic cap. The chip itself is housed inside the plastic portion of the key, and there are different kinds of cuts available on these keys: a regular cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal is absorbed 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 shut down the vehicle immobilizer and allow the engine to begin.
If the vehicle does not recognize the transponder signal as being the proper one, it will prevent the engine from running and will notify you by flashing its lights and sounding a siren. This feature is designed to discourage people from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and determined thief could still evade this system by using a specific device that blocks the signal.
As you can see there are quite number of advantages to having transponder keys. This is something that all vehicle owners should consider if want to safeguard their investment and reduce the risk of theft.
programming car key fobs today can offer more than locking and unlock doors. They can also turn on the vehicle remotely, emit chirping sounds to aid in finding a car, or turn on the heated steering wheel. Many of these extra features may appear convenient but they could make it difficult for you to keep the track of your car keys.
Key fobs make use of radio frequencies to communicate with each other and the car. The frequencies are transmitted by a small antenna in the middle of the key. The signal is encrypted to prevent others from stealing or modifying the signal.
Keyfobs can be programmed in different ways based on the make and model of your vehicle. Certain cars let you do this yourself. However, most newer models require you to visit a professional locksmith or dealer to program a new key fob or an additional one.
When you press the button on a key fob the microchip transmits an indication to the receiver inside the vehicle with which it is linked. The receiver compares this information with the 'allowed' signals inside the fob, and either opens or closes the door. If the information isn't in line an chirping sound is heard and the car isn't allowed to operate.
Once the car has been associated with a particular fob, it only accepts signals from that device. In turn, other fobs won't be able to work with the vehicle, even though they appear similar. This safeguards the integrity of the computer system of the car and prevents unauthorised key fobs from taking control over it.
The majority of newer dealerships will only accept vehicles that have original fobs or genuine replacements supplied 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 aftermarket fobs -- usually those for older models that have less sophisticated systems -- can be programmed by consumers without the need for dealers.
