A keyprogrammer can recode the transponder chip of an entirely new mechanical key or key fob. It can also clone the data from an existing key and allow duplicate keys to be created. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They come with diagnostic software, which allows them to communicate with computers.

Transponder Chips If your car was manufactured in the past 20 years, chances are it has a transponder chip inside of it. It's the small piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own. When it is activated by an electro-magnetic field, the chip emits a low level signal. This signal then gets absorbed by the special antenna that is positioned around the ignition barrel of your vehicle. This allows the vehicle's computer system to verify that the transponder chip inside the key is the correct one for your particular car. This is what stops from modifying or hot-wiring the vehicle's ignition system to turn it on. The chip inside the key verifies that the owner is the one who is the owner of the vehicle. This will help reduce car theft. Regular transponder keys are designed like regular keys and have an outer layer of plastic. The chip itself is housed within the plastic part of the key and there are a few different kinds of cuts available on these keys: a standard cut, a laser cut (also called a sidewinder), or a Ford Tibbe key. The circuit in the induction coil will emit an electrical signal when the transponder is placed in the an ignition barrel. The signal will then get received by the chip and cause it to transmit a signal to the car. If the computer on the car recognizes this signal as the correct one, it will turn off the vehicle's immobilizer and allow the engine to begin. If the car isn't able to recognize the transponder as the correct signal, it will not start the engine, and will notify you via flashing lights and an alarm. This function is designed to discourage people from tampering with the vehicle. However it isn't a foolproof measure of security. A skilled and skilled criminal can still get around this system with a specially designed device that intercepts the signal. As car programmer near me can see there are quite a number of advantages to having a transponder key. Every car owner should consider this if they wish to protect their investment and minimize theft risk. 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 lot Key fobs today can also turn on a heated steering wheel or roll down all of the windows with just a single press. These extra features can make it difficult to locate your car keys. Key fobs are able to communicate with each other and the car using radio frequencies which are transmitted by an antenna in the center of the key. This communication is encrypted, which helps keep others from stealing and replicating the signal. You can program a keyfob in various ways based on the model and brand of your vehicle. Certain models allow you to do this by yourself. However, the majority of newer models require you to visit a professional locksmith or dealer to program a replacement key fob or an additional one. When you press the button on a key fob, the microchip sends an indication to the receiver in the car that it is paired. The receiver compares the information with the 'allowed signals' stored in the key fob and then opens or locks the car's doors. If the data does not match, the car will not be allowed to run. When a car is connected with a specific fob, it will only accept signals from the device that is associated with it. Other fobs will not work with the car, even though they appear similar. This safeguards the integrity of the computer system that runs the vehicle and stops unauthorised key fobs from taking control over it. The majority of newer dealerships will only accept cars that have original fobs or genuine replacements sold by the manufacturer. This is because the only place with the experience to design the replacement fob is the service department of a dealer. Certain aftermarket fobs, typically those for older models that have less advanced systems can be programmed without the need for a dealer.
