Automotive Locksmith Key Programming

Most modern-day cars require some form of key programming. Depending on the car's maker and model, the procedure could be as simple as onboard programming with a spare working key or as complicated as EEPROM or OBD2 programming.

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

Transponder Chips

The majority of newer cars have what are called transponder chips to prevent car theft. These are small computer microchips that emit radio signals at a low level. The microchips have a unique serial number which authenticates your key when you plug it into the ignition barrel. If your vehicle doesn't recognize the signal it will stop the engine. This technology has proven to be an enormous success in preventing car theft. It has also saved many car owners a significant amount of money because they don't need to replace their cars.

In the past car thieves would use a flat screwdriver to force the ignition switch of your car into the "on" mode, or hot-wire it to get around the system. Transponder chips have drastically reduced these types of thefts.

When you insert a transponder key into the ignition, it will send a signal that is picked up by a hidden antenna around the barrel of the ignition. The antenna is programmed to match the frequency of the chip within the key. The computer onboard of the car will then recognise the key as being valid and allow fuel flow and power the starter to begin the engine.
