Automotive Locksmith Key Programming Modern automobiles require some kind of key programming. Depending on the model and make the procedure could be as simple as using an extra key to program the onboard computer or as complicated as EEPROM or OBD2 programming. Most US and Asian automakers share their programming protocol with auto tool makers, so they can design software or hardware for automotive locksmiths. Transponder Chips Transponder chips are found in a variety of newer vehicles to guard against theft of vehicles. These are small computer microchips that emit low-level radio signals. The microchips have an unique serial number that authenticates your key whenever you insert it into the ignition barrel. If your vehicle doesn't recognize the signal it will stop the engine. This technology has been extremely successful in preventing car theft. It has also saved many car owners a significant amount of money as they don't have to buy new their vehicles.

These kinds of thefts have been dramatically decreased with the introduction of the transponder chip. 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 specific frequency of the chip within the key. The onboard computer of the car will recognize the key as valid and will allow fuel flow and power the starter to start the engine. Depending on the manufacturer, certain vehicles can only recognize a specific type of transponder chip.
