Automotive Locksmith Key Programming
Modern cars need some type 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 EEPROM or OBD2 programming.
The majority of US and Asian car manufacturers use the same programming protocols as auto tool makers so that they can develop tools and hardware for automotive locksmiths to use.
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 digital serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your vehicle does not recognize the signal it will shut down. This technology has been extremely successful in preventing car theft. This technology has also helped car owners save a huge amount of money since they don't have to buy new vehicles.

These types of thefts have been dramatically reduced with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it transmits an electrical signal that is detected by a hidden antenna around the barrel of the ignition. The antenna is programmed with the frequency of the chip inside the key. The car's onboard computer will then recognize that the key is genuine and allow fuel to flow, power up the starter or begin it.
