Automotive Locksmith Key Programming Modern cars require some type of key programming. Depending on the car's maker and model, the process could be as simple as programming onboard using an extra working key or as complicated as OBD2 or EEPROM programming. Most US and Asian automakers use the same programming protocols as auto tool makers, which means they can design hardware or software for locksmiths in the automotive industry. Transponder Chips The majority of newer cars have what are called transponder chips to prevent car theft. These are tiny computer microchips which emit radio waves at a low level. They are equipped with a unique digital serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal it will stop the engine. This technology has been an enormous success in preventing theft of cars. It has also saved many car owners a lot of money as they don't have to replace their vehicles. The principle behind the transponder system is to make it impossible for thieves to get into your car without the proper key. In the past car thieves would use an ordinary screwdriver to force the ignition switch of your vehicle to go into “on” mode, or hot-wire it to get around the system. These types of thefts have drastically decreased with the introduction of the transponder chip. When you insert a transponder keys into the ignition, it will send the signal which is detected by a hidden antenna around the barrel of the ignition. 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. Based on the manufacturer, some vehicles will only recognise the specific type of transponder chip.
