Automotive Locksmith Key Programming Modern cars need some kind of key programming. Based on the car's make and model, the procedure can be as easy as onboard programming with an extra working key or as complicated as EEPROM or OBD2 programming. The majority of US and Asian auto manufacturers share their programming protocol with auto tool makers, so they can design software or hardware for automotive locksmiths. Transponder Chips Transponder chips are found in a lot of modern cars to stop theft of cars. 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 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 car theft. This technology has also saved car owners a great amount of money as they do not have to replace their vehicles. The basic concept behind the transponder system is to make it impossible for thieves to get into your vehicle without the correct key. In the past, thieves would use a flat screwdriver to force the ignition switch of your vehicle into the “on” mode or even hot-wire it to bypass the system. Transponder chips have drastically reduced these types of thefts. When you insert a transponder key into the ignition, it will transmit an electrical signal that is detected by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed so that it can read the specific frequency of the chip inside the key. The car's onboard computer will recognise that the key is legitimate and allow fuel to flow, turn the starter or begin it. Some vehicles only recognize certain type of transponder chip, depending on the manufacturer.

For example an “smart key” that lets you call your car to tight parking spaces, like a Tesla or Genesis GV60.
