Automotive Locksmith Key Programming: The Good, The Bad, And The Ugly
Automotive Locksmith Key ProgrammingModern cars need some type of key programming. Based on the model and make, the process may be as simple as using an extra key to program the onboard computer, or as complicated as EEPROM or OBD2 programming.

Transponder Chips
Most modern cars are equipped with what are called transponder chips to prevent car theft. These are tiny computer microchips which emit radio waves at a low level. They have a unique serial number that authenticates your key when you connect it to the ignition barrel. If your vehicle doesn't recognize the signal it will shut down the engine.
