Automotive Locksmith Key Programming The majority of modern cars require some kind of key programming. Depending on the model and manufacturer 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 have a programming protocol that they share with auto tool makers, so they can develop hardware or software 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 microchips in the form of computers that emit radio signals at a low level.

Transponder chips have drastically reduced the number of thefts. When you insert a transponder keys into the ignition, it will transmit the signal which is detected by a hidden antenna that is positioned around the barrel of the ignition. The antenna is programmed to match the frequency of the chip inside the key. The car's onboard computer will detect that the key is genuine and allow fuel to flow, turn up the starter, or even begin it. Based on the manufacturer, certain vehicles can only recognize certain types of transponder chip. Therefore, it is essential that your locksmith in the automotive industry is equipped with the correct equipment to program your keys and remotes for your vehicle.
