There are a few different types of car key programming that can be done by locksmiths who are professionals. Certain types are extremely complex and require sophisticated tools. These tools are generally not available to the general public and are only used by professionals. This kind of programming for car keys is known as EEPROM Programming and requires soldering, electronic expertise, and a lot of time.

Key Programmers

Modern cars require a key-programming procedure to initialize their vehicle's systems and to start the car. In some cases, the key will need to be programmed by an auto locksmith or dealer. The key may not function properly or not start the car in any way. This is because the key has not yet been programmed into the car's system. This can be costly. It's best to have two keys that work for the modern automobile so that you can program the replacement key whenever needed.

A keyprogrammer is a device that can recode the transponder chip into a new key fob or mechanical key. It is also able to clone data of an existing key, allowing duplicates to be created. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They come with diagnostic software, which allows them to communicate with a computer. They also feature a bidirectional user interface for working with an immobilizer system.

There are a variety of keyprogrammers on the market. They come in all sizes, shapes, and colors. Some are inexpensive and others could cost thousands of dollars. Some are made for specific automobiles and provide advanced diagnostics of the car's electronic system.

Consult your owner's guide to learn how to program the mobile key programming to your vehicle. Some manufacturers use proprietary software that allows only dealers to make new keys. Other manufacturers make it easy for anyone to do.

If you're not able to program a new key on your own or request the dealer to program it for you, however it will cost a lot. Another option is to buy an online keyprogrammer. These are cheaper than going to a dealer however, they're not cheap. Before you purchase one, do some research on the seller. Some are not reliable and could damage your vehicle.

Transponder Chips

Transponder chips are likely to be found in vehicles manufactured in the last 20 years. It's the small piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.

The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is then absorbed by a special antenna that is attached to the barrel of ignition. The computer system of the vehicle can then verify that the key's transponder chip is the right one for your car.

This prevents the vehicle from starting by hot-wiring, or by manipulating. The chip inside the key confirms that the owner is the one who is the owner of the vehicle. This will help reduce car theft.

Transponder keys look like normal keys but they have a plastic cap. The chip itself is housed in 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 Ford Tibbe key.

The circuit in the induction coil will emit an electrical signal when the transponder is placed in the ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle. If the car's computer detects this signal as the right one, it will disable the vehicle's immobilizer and allow the engine to begin.

If the car does not recognize the transponder signal as being the proper one, it will keep the engine from running and will notify you by flashing its lights and sounding siren. This is designed to discourage people from attempting to tamper with the vehicle, but it is not a foolproof security measure. A skilled and determined thief could still bypass this system by using a specific device that detects the signal.

You can see that the transponder is an excellent option. This is something that all car owners should consider if they want to protect their investment and decrease the risk of theft.

Key Fobs

Key fobs today do more than just lock and unlock doors. They can also start your car from a distance, make chirping sounds to aid in finding the car, or switch on the heated steering wheel. A lot of these features may appear convenient but they could make it more difficult to keep the keys to your car.

Key fobs communicate with one other and with the car through radio frequencies which are transmitted via a small antenna located in the middle of the key. The communication is encrypted, which helps prevent others from intercepting and re-transmitting the signal.

Keyfobs can be programmed in various ways based on the make and model of your vehicle. Some cars allow you to do this yourself. However, most newer models require you to visit an expert locksmith or dealer to program a new key fob or an additional one.

When you press the button on a key fob the microchip sends a signal to the receiver in the car with which it is linked. The receiver then compares the data with the permitted signals stored on the key fob and then it opens or closes the car's 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 paired with a particular fob, it will only receive signals from that device. Other fobs won't work with the car, even though they appear identical. This safeguards the integrity of the computer system in the vehicle and stops unauthorised key fobs from taking control over it.

Most newer car dealers will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. It is because the only place that has the experience to design an appropriate replacement fob is a dealer's service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
