Automotive Locksmith Key Programming
Modern cars require some type of key programming. Based on the model and manufacturer the process could be as simple as using an additional reprogramme car key to program the onboard computer or as complicated as OBD2 programming or EEPROM.
Most US and Asian automobile manufacturers have programming protocols that they share with auto tool manufacturers in order to create tools and hardware for locksmiths in the automotive industry to use.
Transponder Chips
Most newer cars use transponder chips to prevent reprogramming car keys theft. These are tiny computer microchips that emit radio waves at a low level. The microchips have an unique serial number that authenticates your programmed car keys when you plug it into the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has proved to be an incredible success in preventing auto theft. It also saves many car key programmers owners a lot of money because they don't have to replace their cars.
