Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on the vehicle's make and model, the process can be as easy as onboard programming using a spare key that works or as complex as EEPROM or OBD2 programming.
Most US and Asian auto manufacturers have a programming protocol that they share with auto tool makers, so they can develop software or hardware for locksmiths in the automotive industry.
Transponder Chips
The majority of newer cars have what are called transponder chips to stop car theft. These are tiny computer microchips which emit radio signals of low-level. They have a unique digital serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has proven to be extremely successful in preventing car theft.

These kinds of thefts have been dramatically reduced with the introduction of the transponder chip.
When you insert the transponder key into the ignition the signal is received by an antenna that is concealed around the barrel. This antenna is programmed so that it can detect the specific frequency of the chip inside the key. The car's onboard computer will then recognise that the key is legitimate and allow the fuel to flow, then power the starter or start it.
