Automotive Locksmith Key Programming
Modern cars require some type of key programming. Based on the car's make and model, the process can be as simple as onboard programming with a spare key that works or as complex as EEPROM or OBD2 programming.
Most US and Asian car makers use the same programming protocols as auto tool manufacturers so that they can develop hardware and software for locksmiths in the automotive industry to use.
Transponder Chips
Transponder chips are in a variety of newer vehicles to stop theft of cars. These are microchips in the form of computers which emit radio signals of low-level. They have a unique serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your car isn't able to recognize the signal, it will shut down the engine. This technology has been extremely successful in preventing theft of cars. This technology has also helped car owners save a huge amount of money since they don't have to buy new vehicles.

These kinds of thefts have been drastically reduced with the introduction of the transponder chip.
When you insert a transponder keys into the ignition, it will send the signal which is detected by a hidden antenna circling the barrel of the ignition. The antenna is programmed to match the frequency of the chip in the key. The car's onboard computer will detect that the key is legitimate and allow fuel to flow, power up the starter or start it.

The key programming tool could be a handheld device that is inexpensive device or a fancy one that can perform a wide range of things beyond just key programming (like reading and cloning the eeprom files in the ECU).
