What is a key programmer?

The car programmer is a device that can be used to recodate the transponder in a mechanical key or key FOB. Some modern cars have specially coded transponders in their keys and if the right signal is not received, they will not start or start. In some cases, the new key can be programmed without any special equipment, although many vehicles require a device known as a key programmer. A key programmer can be a separate unit, although they are sometimes integrated into complex scanning tools. Key programmers usually two-way interfaces with a connector on board Diagnostics II (OBD-II). If this happens, it is usually because the transponder inside the key was not encoded in this particular system. The keys can often be obtained from a trade representation or locksmith, even if they need to be encoded regardless of acids. Some vehicles allow the owner to encode their own key, which usually requires the presence of one of their original keyat. This process varies between vehicles, although it usually includes the location of the original key in the ignition, by pressing a special combination of brake and gas pedals, and then replacing the original key with a new one, unexplored.

If the vehicle does not have a self -service function, a key programmer will usually be required. These programmer units are usually two-way OBD-II tools that connect to the same location as other scanning tools. Many vehicle manufacturers sell units that specifically program keys for their vehicles, although generic units can also be found that process different brands and models.

The

process of using the key programmer usually involves connecting the tool to the OBD-II to communicate with Vehicle. Each programming tool has different options and procedures, although they usually allow the operator to pull out the programming data from the computer and thenrewrite the transponder and computer to work together. After using the key programmer, the new key should work just like the old.

Some vehicles use key FOBS instead of traditional lock and glasses. In some cases, the FOB must only be in close proximity to the vehicle to work while other cars require that they are inserted into the dash. Key programmers can be used in many cases with these FOBs, and the process is usually similar to the process used in conventional keys.
