Depending on the vehicle's make and model, the procedure could be as simple as programming onboard using a spare key that works or as complicated as EEPROM or OBD2 programming. Most US and Asian auto manufacturers have a programming protocol that they share with auto tool makers, which means they can create tools or hardware for automotive locksmiths. Transponder Chips Most newer cars use what are called transponder chips in order to prevent theft. These are tiny computer microchips that emit low-level radio waves. The microchips are equipped with a unique serial number that authenticates your keys when you connect it to the ignition barrel. If doesn't recognize the signal, it will shut down the engine. This technology has proven to be a huge success in preventing car theft. This technology has also helped car owners save a good deal of money by not having to purchase new cars. The principle behind the transponder system is to make it impossible for thieves to open the doors of your vehicle without a valid key. In the past car thieves used a flat screwdriver to force the ignition switch in your car into the "on" mode or even hot-wire it to get around the system. These types of thefts have been drastically decreased with the introduction of the transponder chip. When you insert a transponder keys into the ignition, it will transmit a signal that is received by a hidden antenna circling the barrel of the ignition. The antenna is programmed to match the frequency of the chip in the key. The car's computer onboard will recognize that the key is genuine and allow fuel to flow, turn up the starter or start it. Certain vehicles only recognize a certain type of transponder chip according
