10 Things You'll Need To Be Aware Of Automotive Locksmith Key Programming
Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Based on the car's make and model, the process can be as easy as onboard programming using an extra working key or as complex as OBD2 or EEPROM programming.
The majority of US and Asian auto manufacturers share their programming protocol with auto tool makers, which means they can develop tools or hardware for locksmiths in the automotive industry.
Transponder Chips
Most modern cars are equipped with 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 plugged into the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has proven to be a huge success in preventing theft of cars.
