Automotive Locksmith Key Programming: The Good, The Bad, And The Ugly
Automotive Locksmith Key Programming

Modern vehicles require some form 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 complex as OBD2 programming or EEPROM.
The majority of US and Asian car makers have programming protocols that they share with auto tool makers to allow them to develop software and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are in a variety of newer vehicles to prevent car theft. These are tiny computer microchips which emit low-level radio waves. The microchips are equipped with an unique serial number that authenticates your key whenever you plug it into the ignition barrel. If your car isn't able to recognize the signal, it will shut down the engine. This technology has proven to be extremely successful in preventing car theft.

In the past, thieves would simply force your car's ignition switch into the "on" position using a flat screwdriver or even hot-wire the car to bypass the system entirely. Transponder chips have dramatically reduced the number of thefts.
When you insert a transponder key into the ignition, it will transmit the signal which is received by a hidden antenna circling the barrel of the ignition. This antenna is programmed so that it can detect the particular frequency of the chip inside the key. The computer onboard of the car will recognize the key as being valid and allow fuel flow, power the starter or start the engine.
