Automotive Locksmith Key Programming
Modern cars need some kind of key programming. Depending on your vehicle's model and manufacturer the procedure could be as simple as using an extra key to program the onboard computer or as complex as OBD2 programming or EEPROM.
Most US and Asian auto manufacturers share their programming protocol with auto tool makers, which means they can develop tools or hardware for locksmiths in the automotive industry.
Transponder Chips
The majority of newer cars have what are called transponder chips in order to prevent theft. These are microchips in the form of computers that emit low-level radio signals. The microchips have a unique serial number which authenticates your key whenever you connect it to the ignition barrel. If your vehicle does not recognize the signal and the engine is shut down. This technology has proven to be extremely successful in preventing theft of cars. 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 decreased with the introduction of the transponder chip.
When you insert the transponder key in the ignition the signal is received by an antenna that is hidden within the barrel. This antenna is programmed with the frequency of the chip inside the key. The onboard computer in the car will recognize the key as being valid and allow fuel flow and start the starter. start the engine.
