Automotive Locksmith Key Programming
Most modern-day cars require some form of key programming. Depending on the model and manufacturer, the process may be as simple as using a spare key to program the onboard computer, or as complex as OBD2 programming or EEPROM.
Most US and Asian automakers use the same programming protocols as auto tool makers, which means they can develop hardware or software for automotive locksmiths.
Transponder Chips
The majority of newer cars have transponder chips in order to prevent theft. These are microchips in the form of computers that emit radio signals at a low level. The microchips are equipped with a unique serial number which authenticates your key when 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 an enormous success in preventing auto theft.

Transponder chips have drastically decreased the likelihood of theft.
When you insert a transponder keys into the ignition, it will send an electrical signal that is detected by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed so that it can read the specific frequency of the chip inside the key. The car's computer onboard will recognize that the key is genuine and allow fuel to flow, turn the starter or begin it.

Programming EEPROM is another method that can be used to program new car keys. It is more complicated and requires a deep understanding of electronic systems. It is best to delegate it to a professional who has knowledge of these systems.
Locksmiths can program keys quickly by using onboard programming. It can take as little as a minute when everything is executed correctly. If the key isn't placed in the right situation or the procedure isn't strictly followed, it could take up to a half hour.
