Automotive Locksmith Key Programming Modern cars require some type of key programming. Depending on the vehicle's make and model, the procedure can be as simple as onboard programming with a spare key that works or as complicated as EEPROM or OBD2 programming. Most US and Asian automobile manufacturers share their programming protocols with auto tool manufacturers in order to create software and hardware for locksmiths working in automotive vehicles. Transponder Chips The majority of newer cars have transponder chips to stop car theft. These are tiny computer microchips that emit radio waves 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 isn't able to recognize the signal it will shut down. This technology has proven to be a huge success in preventing theft of cars. It also saves many car owners a significant amount of money since they don't need to replace their vehicles. The principle behind the transponder system is to make it impossible for thieves to open the doors of your car without the proper key.

These types of thefts have drastically reduced thanks to the introduction of the transponder chip. When you insert the transponder keys into the ignition, the signal is received by an antenna that is concealed around the barrel. The antenna is programmed to detect the particular frequency of the chip within the key. The onboard computer in the car will then recognise the key as valid and allow fuel flow, power the starter or begin the engine. Certain vehicles only recognize a certain type of transponder chip according to the manufacturer.
