Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on the car's maker and model, the process can be as simple as programming onboard using an extra working key or as complicated as OBD2 or EEPROM programming.
Most US and Asian car makers have programming protocols that they share with auto tool makers in order to create software and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Most modern cars are equipped with what are called transponder chips to stop car theft. These are small computer microchips that emit low-level radio signals. They are equipped with a unique digital serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle isn't able to recognize the signal, the engine will be shut down. This technology has been extremely successful in preventing car theft. It has also saved many car owners a significant amount of money because they don't have to replace their vehicles.
The basic concept behind the transponder system is to make it impossible for thieves to open the doors of your vehicle without a valid key. In the past, thieves would use a flat screwdriver to force the ignition switch of your vehicle into the "on" mode or even hot-wire it to get around the system. These kinds of thefts have drastically reduced with the introduction of the transponder chip.
When you place the transponder key into the ignition the signal is received by an antenna that is concealed around the barrel. This antenna is programmed with the frequency of the chip inside the key. The onboard computer of the car will then recognise the key as being valid and will allow fuel flow and power the starter to start the engine.
