Automotive Locksmith Key Programming The majority of modern cars require some type of key programming. Depending on your vehicle's model and manufacturer, the process may be as simple as using an additional key to program the onboard computer or as complicated as EEPROM or OBD2 programming. Most US and Asian car manufacturers use the same programming protocols as auto tool manufacturers to allow them to develop tools and hardware for locksmiths in the automotive industry to use. Transponder Chips The majority of newer cars have what are called transponder chips to stop car theft. These are tiny computer microchips that emit radio waves of low-level. The microchips are equipped with an unique serial number that authenticates your keys when you connect it to the ignition barrel. If your vehicle does not recognize the signal it will shut down. This technology has proven to be a huge success in preventing car theft. It has also saved many car owners a significant amount of money because they don't need to replace their cars.

These kinds of thefts have drastically reduced thanks to the introduction of the transponder chip. When you place the transponder key into the ignition the signal is received by an antenna that is hidden within the barrel. This antenna is programmed with the frequency of the chip within the key. The computer onboard of the car will then recognise the key as valid and will allow fuel flow and start the starter. begin the engine.
