Automotive Locksmith Key Programming
The majority of modern cars require some kind of key programming. Depending on the model and manufacturer the procedure could be as simple as using an extra key to program the onboard computer, or as complex as OBD2 programming or EEPROM.
Most US and Asian car makers share their programming protocols with auto tool makers so that they can develop hardware and software for automotive locksmiths to use.
Transponder Chips
Most modern cars are equipped with what are called transponder chips to prevent car theft. These are small computer microchips which emit radio signals of low-level. The microchips are equipped with a unique serial number that authenticates your keys when you plug it into the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has been an immense success in stopping auto theft.

This antenna is programmed so that it can detect the specific frequency of the chip within the key.
