Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the vehicle's make and model, the procedure can be as simple as onboard programming with an extra working key or as complicated as EEPROM or OBD2 programming.
Most US and Asian car manufacturers use the same programming protocols as auto tool manufacturers in order to create tools and hardware for automotive locksmiths to use.
Transponder Chips
Most newer cars use what are called transponder chips to prevent car theft. These are tiny computer microchips which emit radio signals of low-level. They have a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle does not recognize the signal, the engine will be shut down. This technology has been a huge success in preventing theft of cars.

Transponder chips have dramatically reduced the number of thefts.
