Key Programmers Modern vehicles often require a key programming procedure to initialize the vehicle's system and allow the vehicle to begin. In a number of cases the key needs to be set up by the auto locksmith or dealer. This is because the key might not function properly, or it will not start the vehicle at all. The reason for this is that the new key hasn't been programmed to the car's system, and this could be quite expensive. This is why it's a good idea to always have two keys working for modern vehicles and to have the replacement key programmed when necessary. A keyprogrammer is a device that recodes the transponder chip on an entirely new mechanical or key fob key. It can also clone the data of an existing key to create duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They have diagnostic software that allows them to communicate with the computer and also provide bidirectional interfaces to work with the immobilizer system. There are a variety of keyprogrammers on the market. They are available in a variety of sizes, shapes and colors. Some are inexpensive, while others could cost thousands of dollars. Some are specifically designed for certain types of cars, and they can even provide advanced diagnostics for the vehicle's electronic systems.

Other manufacturers make it easy for anyone to do. If you are not able to program the new key yourself or by yourself, you can ask your dealer to do it, but it will cost a lot. Another option is to buy a keyprogrammer online. They're less expensive than visiting a dealership however, they aren't cheap. Before purchasing one, do some research on the seller. Some aren't trustworthy and could cause damage to your vehicle. Transponder Chips If your car was built within the last 20 years, chances are it contains a transponder chip within of it. This is the little piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own. When activated by an electro-magnetic field the chip emits a low-level signal. The signal is absorbed by a special antenna attached to the barrel of ignition. This allows the car's computer system to confirm that the transponder chip that is in the key is the right one for your specific vehicle. This prevents the vehicle from being started by either 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 helps to reduce the risk of theft from your car. Transponder keys resemble regular metal keys but they have caps made of plastic. The chip itself is housed inside the plastic portion of the key, and there are different kinds of cuts available on the keys: a cut laser cut (also called a sidewinder), or a Ford Tibbe key. A circuit inside the induction coil will emit an electrical signal when the transponder is placed in the ignition barrel. The signal will be absorbed by the chip, causing it to send a signal back to the car. If the computer onboard the car recognizes the signal as correct, it will disable vehicle immobilizer so that the engine can start. If the car does not recognize the transponder signal as being the correct one, it will stop the engine from starting and will alert you by flashing its lights and sounding siren. This is designed to deter people from trying to tamper with the vehicle, but it isn't a foolproof security measure. A determined and skilled thief could still bypass this system by using a specific device that blocks the signal. It is evident that a transponder is a great option. All car owners should consider this in order to safeguard their investment and decrease the chance of theft. Key Fobs In addition to locking and unlocking doors, starting the car remotely or making sound chirps to help locate the car in a parking space, today's key fobs can also turn on a heated steering wheel or roll down all windows with just a single click. These extra features could make it difficult to find your car keys. Key fobs communicate with one other and with the car through radio frequencies which are transmitted by an antenna in the center of the key. The signal is encrypted to block other key fobs from intercepting or replicating the signal. There are several ways to program a key fob based on the vehicle's make and model. You may be able to do it yourself, but most newer cars require that you visit a locksmith shop or a professional to program a replacement or additional fob. When you press the button on a key fob the microchip sends a signal to the receiver in the car that it is paired. The receiver compared the information with the 'allowed signals' stored in the key fob, and then opens or locks the car's doors. 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 will not work with the car, even if they appear identical. This ensures the security of the computer system of the vehicle and stops unauthorized key fobs gaining control over it. Most dealerships with newer cars will only deal with cars with original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security skills that is only available in the dealer service department. However, some fobs from the aftermarket — usually those for older models with less sophisticated systems — can be programmed by consumers without the need for a dealership.
