Key Programmers Modern vehicles require a key-programming procedure to initialize their vehicle's systems and start the car.

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 good idea to always have two working keys for a modern car and to have the replacement key programmed when necessary. A keyprogrammer can recode a transponder chip on a new mechanical key or key fob. It can also clone the data of an existing key which allows duplicate keys to be created. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They have diagnostic software that allows them to communicate with computers and also provide bidirectional interfaces to work with the immobilizer system.

They're less expensive than visiting a dealer, but still not inexpensive. Make sure you research the seller before purchasing one – some are not reliable and can damage your car. Transponder Chips If your car was manufactured in the past 20 years, then it has a transponder inside of it. This is a little plastic thing in the head of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle. The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is fitted around the ignition barrel of your vehicle. The computer system of the vehicle will then confirm that the key's transponder chip is the right one for your car. This is what stops hot-wiring or tampering with the ignition system of the vehicle to start it. The chip in the key also verifies that you are the genuine owner of the vehicle. This helps to prevent the possibility of theft from your vehicle. Transponder keys appear like normal keys but they have a plastic cap. The chip is contained inside the plastic portion of the key, and there are different types of cuts on these keys: a cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key. A circuit within the induction coil emits an electrical signal when the transponder is inserted into an ignition barrel. The signal is received by the chip which then transmits a signal the vehicle. If the onboard car computer detects this signal as the correct one, it will disable the vehicle immobilizer and allow the engine to begin. If the car doesn't recognize the transponder as a valid signal, it will not start the engine, and will alert you with flashing lights and a siren. This feature is designed to discourage individuals from tampering with the vehicle. However, it is not an unbreakable security measure. A skilled and determined criminal may still be able to get around this system using a device that can take over the signal. As you can see there are quite a number of advantages to having transponder keys. All car owners should take this into consideration when they want to safeguard their investment and decrease the chance of theft. Key Fobs Key fobs today offer more than locking and unlock doors. They can also turn on the vehicle from a distance, make chirping sounds to aid in finding a car, or turn on the heated steering wheel. A lot of these additional features might seem useful however they could make it more difficult to keep track of your car keys. Key fobs use radio frequencies to communicate with one another and with the car. These frequencies are transmitted through a small antenna located in the middle of the key. The transmission is encrypted, which helps prevent others from intercepting and retransmitting the signal. You can program a keyfob in a variety of ways depending on the model and make of your car. It is possible to do this yourself, but the majority of newer vehicles require a dealer or professional locksmith to program a replacement or a second fob. When you press the button on your key fob, the microchip inside transmits an informational code to the car's receiver it is paired with. The receiver compares this information to the 'allowed' signals in the fob and then 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. When a car is connected with a specific fob, it will only accept signals from that device. This means that other fobs will not work with the vehicle, even though they appear similar. This protects the integrity of the computer system that runs the car and blocks unauthorized key fobs gaining control of it. The majority of newer dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security expertise that is only available in the dealer's service department. However, some fobs from the aftermarket — usually those for older models that have less sophisticated systems can be programmed by the consumer without the need for a dealership.
