10 Wrong Answers To Common Automotive Locksmith Key Programming Questions Do You Know The Correct Answers?
Automotive Locksmith Key ProgrammingModern cars need some form of key programming. Based on the car's make and model, the process could be as simple as onboard programming using a spare working key or as complicated as EEPROM or OBD2 programming.

Transponder Chips
Transponder chips are found in many newer cars to guard against theft of vehicles. These are tiny computer microchips which emit radio waves at a low level. They are equipped with a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal it will shut down. This technology has proved to be an incredible success in preventing auto theft.
