Automotive Locksmith Key Programming
Modern cars need some form of key programming. Depending on the vehicle's make and model, the process can be as simple as onboard programming with a spare key that works or as complicated as EEPROM or OBD2 programming.
Most US and Asian car manufacturers have programming protocols that they share with auto tool makers so that they can develop software and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are in a lot of modern cars to guard against theft of vehicles. These are small computer microchips which emit radio signals of low-level. The microchips have a unique serial number which authenticates your keys when you insert it into the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down.

When you place the transponder key into the ignition, the signal is picked up by an antenna that is concealed around the barrel. This antenna is programmed to detect the particular frequency of the chip within the key. The car's onboard computer will detect that the key is legitimate and allow fuel to flow, turn the starter or start it.
