Automotive Locksmith Key Programming Modern automobiles require some kind of key programming Based on the model and manufacturer the process could be as simple as using an extra key to program the

your car to go into on mode or hotwire it in order to get around the system These kinds of thefts have drastically decreased with the introduction of the transponder chip When you insert a transponder keys into the ignition it transmits a signal that is received by a hidden antenna that is positioned around the barrel of the ignition The antenna is programmed to match the frequency of the chip in the key The cars onboard computer will recognise that the key is valid and allow fuel to flow turn up the starter or start it Some vehicles only recognize a certain type of transponder chips depending on the manufacturer This is why its important to ensure that your automotive locksmith has the appropriate equipment to program your cars key and fobs correctly A good automotive locksmith should have
