Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Based on the model and manufacturer the process could be as simple as using a spare key to programme the computer onboard, or as complicated as OBD2 programming or EEPROM.
Most US and Asian auto manufacturers use the same programming protocols as auto tool makers, so they can design hardware or software for automotive locksmiths.
