Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the vehicle's make and model, the procedure can be as simple as onboard programming with a spare working key or as complicated as OBD2 or EEPROM programming.
The majority of US and Asian automakers use the same programming protocols as auto tool manufacturers, so they can design tools or hardware for automotive locksmiths.
Transponder Chips
Transponder chips are in a lot of modern cars to prevent car theft. These are tiny computer microchips which emit radio signals of low-level. They have 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, the engine will be shut down. This technology has proven to be an incredible success in preventing auto theft.
