Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on your vehicle's model and make the process could be as simple as using a spare key to program the onboard computer, or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian automakers use the same programming protocols as auto tool manufacturers, so they can design software or hardware for automotive locksmiths.
Transponder Chips
Most newer cars use what are called transponder chips to prevent car theft. These are microchips in the form of computers which emit radio signals of low-level. They have a unique serial number that authenticates the key to your car 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 proven to be an enormous success in preventing theft of cars. It has also saved many car owners a lot of money because they don't need to replace their vehicles.

These types of thefts have been dramatically 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 that is concealed around the barrel. The antenna is programmed with the frequency of the chip within the key. The car's computer onboard will recognise that the key is genuine and allow fuel to flow, turn up the starter, or even start it.
