Automotive Locksmith Key Programming 10 Things I Wish I'd Known Earlier

Automotive Locksmith Key Programming

The majority of modern cars require some form of key programming. Based on the model and manufacturer, the process may be as simple as using an extra key to programme the computer onboard, or as complex as EEPROM or OBD2 programming.

Most US and Asian auto manufacturers share their programming protocol with auto tool manufacturers, so they can create software or hardware for locksmiths in the automotive industry.

Transponder Chips

Transponder chips are found in many newer cars to stop theft of cars. These are tiny computer microchips that emit radio waves at a low level. They have a unique digital serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your car doesn't recognise the signal, it will shut down the engine.

This antenna is programmed so that it can detect the particular frequency of the chip within the key.
