Automotive Locksmith Key Programming The majority of modern cars require some kind of key programming. Depending on the vehicle's make and model, the procedure can be as simple as onboard programming with an extra working key or as complicated as OBD2 or EEPROM programming. Most US and Asian car makers share their programming protocols with auto tool manufacturers so that they can develop tools and hardware for locksmiths in the automotive industry to use. Transponder Chips Most newer cars use transponder chips to stop car theft. These are tiny computer microchips which emit radio waves of low-level. They have a unique digital serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has been a huge success in preventing theft of cars.

These types of thefts have been drastically reduced thanks to the introduction of the transponder chip. When you insert a transponder keys into the ignition, it will send the signal which is picked up by a hidden antenna circling the barrel of the ignition. This antenna is programmed to read the specific frequency of the chip within the key. The car's onboard computer will then detect that the key is genuine and allow the fuel to flow, then power the starter or begin it. Some vehicles only recognize a certain type of transponder chips depending on the manufacturer. auto car key programmer near me is why it's crucial to make sure that your locksmith for automotive is equipped to program your car's keys and fobs properly.
