Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the vehicle's make and model, the procedure can be as simple as onboard programming with a spare key that works or as complex as OBD2 or EEPROM programming.
Most US and Asian automobile manufacturers have programming protocols that they share with auto tool makers in order to create tools and hardware for automotive locksmiths to use.
Transponder Chips
Most newer cars use what are called transponder chips in order to prevent theft. These are tiny computer microchips which emit radio signals of low-level. The microchips are equipped with a unique serial number that authenticates your key whenever you insert it into the ignition barrel. If your vehicle does not recognize the signal and the engine is shut down. This technology has proven to be an enormous success in preventing auto theft. It also saves many car owners a significant amount of money because they don't have to buy new their vehicles.

Transponder chips have drastically 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 match the frequency of the chip inside the key. The computer onboard of the car will then recognise the key as being valid and will allow fuel flow, power the starter or start the engine.
Some vehicles only recognize a specific type of transponder chip, depending on the manufacturer. Therefore, it is essential that your automotive locksmith is equipped with the right equipment to program your car's keys and remotes.
