Automotive Locksmith Key Programming The majority of modern cars require some form of key programming. Based on the model and make the procedure could be as simple as using an extra key to programme the computer onboard, or as complicated as OBD2 programming or EEPROM. Most US and Asian automakers use the same programming protocols as auto tool manufacturers, so they can create software or hardware for locksmiths in the automotive industry. Transponder Chips Most modern cars are equipped with what are called transponder chips to stop car theft. These are tiny computer microchips that emit low-level radio signals. They have a unique digital serial number that authenticates the key to your car 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 a huge success in preventing car theft. This technology has also helped car owners save a huge deal of money by not having to purchase new cars.

These types of thefts have drastically reduced with the introduction of the transponder chip. When you insert a transponder keys into the ignition, it transmits the signal which is picked up by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed with the frequency of the chip inside the key. The onboard computer in the car will recognize the key as being valid and allow fuel flow, power the starter or start the engine. Certain vehicles only recognize a specific type of transponder chip according to the manufacturer.
