Automotive Locksmith Key Programming The majority of modern cars require some kind of key programming. Depending on the car's maker and model, the procedure can be as simple as programming onboard using a spare key that works or as complex as EEPROM or OBD2 programming. The majority of US and Asian auto manufacturers use the same programming protocols as auto tool makers, which means they can design software or hardware for automotive locksmiths. Transponder Chips Transponder chips are in a variety of newer vehicles to prevent car theft. These are microchips in the form of computers that emit radio signals at a low level. They have a unique serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle does not recognize the signal, the engine will be shut down. This technology has been extremely successful in preventing theft of cars. It has also saved many car owners a lot of money because they don't have to buy new their vehicles.

These types of thefts have been drastically reduced thanks to the introduction of the transponder chip. When you insert a transponder key into the ignition, it transmits the signal which is picked up by a hidden antenna around the barrel of the ignition. The antenna is programmed with the frequency of the chip within the key. The car's onboard computer will then recognise that the key is genuine and allow fuel to flow, power up the starter, or even start it. reprogram car key recognize certain type of transponder chips, depending on the manufacturer.
