Automotive Locksmith Key Programming

Modern automobiles require some kind of key programming. Based on the model and make, the process may be as simple as using a spare key to program the onboard computer, or as complex as EEPROM or OBD2 programming.

Most US and Asian car makers have programming protocols that they share with auto tool makers in order to create hardware and software for automotive locksmiths to use.

Transponder Chips

Most newer cars use transponder chips to stop car theft. These are microchips in the form of computers that emit radio signals at a low level. The microchips are equipped with an unique serial number that authenticates your mobile key programming whenever you insert it into the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has been an immense success in stopping auto theft.

These kinds of thefts have been drastically reduced with the introduction of the transponder chip.

When you insert the transponder keys into the ignition the signal is picked up by an antenna hidden around the barrel. The antenna is programmed to match the frequency of the chip inside the key. The onboard computer in the car will then recognise the key as being valid and allow fuel flow, power the starter or start the engine.
