Automotive Locksmith Key ProgrammingModern automobiles require some kind of key programming. Based on the model and make the process 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 auto manufacturers use the same programming protocols as auto tool makers, so they can create software or hardware for automotive locksmiths.Transponder ChipsMost newer cars use transponder chips to stop car theft. These are tiny computer microchips that emit low-level radio waves. They have a unique serial number which authenticates your keys when you connect it to 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 a huge success in preventing theft of cars. It also saves many car owners a lot of money since they don't have to replace their cars.The basic idea behind the transponder system is to make it difficult for thieves to open the doors of your vehicle without a valid key. In the past, car thieves would force your ignition switch to the "on" position using an ordinary screwdriver or make use of hot-wires to bypass the system entirely. Transponder chips have drastically reduced these types of thefts.When you insert a transponder key into the ignition, it will send a signal that is detected by a hidden antenna that is positioned around the barrel of the ignition. The antenna is programmed to match the frequency of the chip within the key. The car's onboard computer will recognize that the key is legitimate and allow fuel to flow, turn up the starter or start it.Some vehicles only recognize specific type of transponder chip depending on the manufacturer. This is why it's essential to ensure that your automotive locksmith has the right equipment to program your vehicle's keys and fobs properly.A good automotive locksmith should have a multi-vehicle key programming device that works with different car manufacturers and models.
