The Ultimate Cheat Sheet On Automotive Locksmith Key Programming

Automotive Locksmith Key Programming

The majority of modern cars require some kind of key programming. Based on Full Record and manufacturer the process could be as simple as using a spare key to program the onboard computer 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 design tools or hardware for automotive locksmiths.

Transponder Chips

Most modern cars are equipped with what are called transponder chips in order to prevent theft. These are tiny computer microchips that emit radio waves of low-level. They have a unique serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle isn't able to recognize the signal it will shut down.

Transponder chips have dramatically reduced these types of thefts.

When you place the transponder key into the ignition the signal is received by an antenna that is concealed around the barrel. The antenna is programmed to detect the specific frequency of the chip inside the key. The computer onboard of the car will then recognize the key as being valid and will allow fuel flow and power the starter to begin the engine.
