Automotive Locksmith Key Programming Modern cars need some type of key programming. Based on the model and manufacturer the procedure could be as simple as using a spare key to program the onboard computer, or as complex as OBD2 programming or EEPROM. The majority of US and Asian automakers share their programming protocol with auto tool makers, which means they can create hardware or software for automotive locksmiths. Transponder Chips Transponder chips are found in a lot of modern cars to prevent car theft. These are microchips in the form of computers which emit radio signals of low-level. The microchips have an unique serial number that authenticates your keys when you insert it into the ignition barrel. If your vehicle isn't able to recognize the signal and the engine is shut down. This technology has proven to be an incredible success in preventing auto theft. This technology has also helped car owners save a huge amount of money as they do not have to replace their vehicles.

These types of thefts have drastically reduced with the introduction of the transponder chip. When you place the transponder key into the ignition the signal is received by an antenna that is concealed around the barrel. The antenna is programmed to match the frequency of the chip within the key. The onboard computer of the car will recognize the key as being valid and allow fuel flow and start the starter. start the engine. Depending on the manufacturer, certain vehicles can only accept a specific type of transponder chip.
