20 Myths About Automotive Locksmith Key Programming: Dispelled
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 an additional key to program the onboard computer, or as complicated as OBD2 programming or EEPROM.
The majority of US and Asian automobile manufacturers use the same programming protocols as auto tool makers to allow them to develop tools and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Most newer cars use what are called transponder chips in order to prevent theft. These are tiny computer microchips that emit radio waves at a low level. The microchips have an unique serial number that authenticates your key when you insert it into the ignition barrel. If your car doesn't recognise the signal it will shut down the engine.
