Automotive Locksmith Key Programming
Most modern-day cars require some type of key programming. Depending on the vehicle's make and model, the process can be as simple as onboard programming with a spare working key or as complex as EEPROM or OBD2 programming.
Most US and Asian car makers share their programming protocols with auto tool makers to allow them to develop tools and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are found in many newer cars to guard against theft of vehicles. These are microchips in the form of computers which emit radio signals of low-level. They have a unique serial number which authenticates your key when you insert it into the ignition barrel. If your vehicle isn't able to recognize the signal, the engine will be shut down.

Transponder chips have drastically reduced the number of thefts.
