Key Programmers Modern automobiles require a key-programming process to start the vehicle's system and then start the vehicle. In some instances the key needs to be programmed by the dealer or auto locksmith. This is because the key may not work properly, or it will 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. This is why it's a great idea to always have two keys working for a modern automobile and have the replacement key programmed if necessary. A keyprogrammer is a device which can reprogram the transponder chip in the form of a new key fob or mechanical key. It is also able to copy the data of 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 allows them to communicate with computers, and they also have an interface that works bidirectionally with the immobilizer system. There are a variety of keyprogrammers available on the market. They come in all sizes, shapes, and colors. Certain keyprogrammers are affordable while others could cost thousands of dollars. Some are made for specific automobiles and offer advanced diagnostics of the vehicle's electronic system. If you're interested in programming an entirely new key for your vehicle, refer to the owner's manual for instructions on how to do it. Certain manufacturers have proprietary software that allows only the dealership to create new keys. Other manufacturers make it easy for anyone to complete. If you are unable to program the new key on your own and you are unable to do it, then ask your dealer to do it, but it will be very costly. You can also purchase a keyprogrammer from the internet. They are less expensive than visiting a dealer however, they aren't cheap. Before buying one do some research on the seller. Some aren't reliable and could damage your vehicle. Transponder Chips Transponder chips are likely be found in cars that were manufactured within the past 20 years. It's a small plastic piece on the back of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own. The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then taken up by an antenna attached to the ignition barrel. The computer system in the vehicle will then confirm that the chip in the key's transponder is the right one for your car. This is what prevents doing hot-wiring or altering the ignition system of the vehicle to get it started. The chip inside the key also verifies that you are the genuine owner of the vehicle. This helps to reduce the risk of theft from your car. Transponder keys look like regular keys made of metal but they have caps made of plastic. The chip is inside the plastic portion of these keys. There are several different cuts that are a standard cut, laser cut (also called a sidewinder or Ford Tibbe), and Ford Tibbe. A circuit inside the induction coil emits signals when the transponder is placed in the ignition barrel. The signal will be received by the chip, causing it to transmit a signal back to the car. If the computer onboard the car is able to recognize the signal as correct, it will disable vehicle immobilizer, allowing the engine to start. If the car isn't able to recognize the transponder as a valid signal, it won't start the engine and alert you with flashing lights and siren. This feature is designed to discourage individuals from tampering with the vehicle. However it's not an absolute security measure. A skilled and committed thief may still be able to bypass this system by using a device that can intercept the signal. As you can see, there are quite a few advantages to getting transponder keys. Every car owner should consider this in order to safeguard their investment and decrease the risk of theft. Key Fobs In addition to locking and unlocking doors, starting the car from a distance or making sound chirps to help locate the car in a parking space Key fobs today can also turn on the heated steering wheel or roll down all windows with a single press. Many of these extra features may appear convenient, but they can also make it harder for you to keep track of your car keys. Key fobs are able to communicate with each with the car via radio frequencies that are transmitted via an antenna that is located in the middle of the key. The signal is encrypted to block other key fobs from intercepting or replicating the signal. There are a few different ways to program a key fob based on your vehicle's make and model. You may be able to do it yourself, however most modern automobiles require a dealer or professional locksmith to program a replacement or additional fob. When you press the button on a key fob the microchip sends a signal to the receiver inside the vehicle with which it is linked. The receiver compared this information to the 'allowed' signals stored inside the fob, and either opens or closes the door. If the information doesn't match the signals, the car will not be allowed to drive. After the car has been connected to a specific fob, it can only receive signals from the device. Other fobs will not work with the car, even if they look like. This safeguards the integrity of the computer system in the vehicle and stops unauthorized key fobs gaining control of it. Most newer car dealerships will only deal with cars that have original fobs or genuine replacements offered by the manufacturer. This is because the only place with the knowledge to create an appropriate replacement fob is the service department of the dealer. Certain aftermarket fobs, typically those for older models that have less sophisticated systems, can be programmed without the need for a dealership.
