Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the model and make, the process may be as simple as using a spare key to program the onboard computer or as complicated as OBD2 programming or EEPROM.
The majority of US and Asian car manufacturers have programming protocols that they share with auto tool manufacturers in order to create hardware and software for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are used in many newer cars to stop theft of cars. These are tiny computer microchips that emit radio waves of low-level. They have a unique digital serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal it will stop the engine.

When you place the transponder key in the ignition the signal is picked up by an antenna that is hidden within the barrel. This antenna is programmed with the frequency of the chip inside the key. The car's onboard computer will then recognise that the key is legitimate and allow fuel to flow, power the starter or start it.
Some vehicles only recognize a certain type of transponder chips depending on the manufacturer. This is why it's crucial to make sure that your automotive locksmith has the appropriate equipment to program your car's key and fobs correctly.
