Automotive Locksmith Key Programming: The Good The Bad And The Ugly
Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Based on the car's make and model, the procedure can be as easy as onboard programming using a spare working key or as complex as OBD2 or EEPROM programming.
The majority of US and Asian car manufacturers share their programming protocols with auto tool manufacturers in order to create software and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Most newer cars use what are called transponder chips in order to prevent theft. These are tiny computer microchips which emit radio waves at a low level. They have a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal it will shut down the engine. This technology has been an enormous success in preventing auto theft. It also saves many car owners a significant amount of money since they don't need to replace their cars.

This antenna is programmed with the frequency of the chip inside the key. The onboard computer in the car will then recognise the key as valid and allow fuel flow and power the starter to begin the engine.
