Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on your vehicle's model and manufacturer the process could be as simple as using an additional key to programme the computer onboard, or as complicated as EEPROM or OBD2 programming.
Most US and Asian auto manufacturers share their programming protocol with auto tool makers, which means they can develop tools or hardware for automotive locksmiths.
Transponder Chips
Most newer cars use transponder chips in order to prevent theft. These are tiny computer microchips which emit radio signals of low-level. The microchips have an unique serial number that authenticates your keys when you plug it into the ignition barrel. If your vehicle isn't able to recognize the signal it will shut down. This technology has been an enormous success in preventing car theft. It has also saved many car owners a lot of money since they don't need to replace their cars.

In the past car thieves used an ordinary screwdriver to force the ignition switch of your vehicle into the "on" mode or even wire it hot to bypass the system. These kinds of thefts have drastically decreased with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it will send an electrical signal that is received by a hidden antenna circling the barrel of the ignition. This antenna is programmed with the frequency of the chip in 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 begin the engine.
