Automotive Locksmith Key Programming Modern vehicles require some form of key programming Depending on the cars maker and model the process can be as easy as onboard programming with a spare working key or as complex as OBD2 or EEPROM programming The majority of US and Asian automakers use the same programming protocols as auto tool makers so they can develop software or hardware for automotive locksmiths Transponder Chips The majority of newer cars have what are called transponder chips to stop car theft These are tiny computer microchips which emit radio waves of lowlevel They have a unique serial number that authenticates your key whenever you insert it into the ignition barrel If your car doesnt recognise the signal it will shut down the engine This technology has proven to be

hotwire the car to bypass the system entirely Transponder chips have drastically decreased the likelihood of theft When you insert a transponder key into the ignition it will send a signal that is picked up by a hidden antenna around the barrel of the ignition This antenna is programmed so that it can read the specific frequency of the chip inside the key The onboard computer in the car will then recognise the key as being valid and will allow fuel flow and power the starter to start the engine Depending on the manufacturer certain vehicles can only recognize certain types of transponder chip It is therefore important that your automotive locksmith is equipped with the appropriate equipment to program your cars keys and remotes A reputable locksmith for automotive needs to have a

alternative key fob from the dealer or from another retailer and have it programmable by a locksmith for your vehicle to be compatible with your specific vehicle This is because most of the major US and Asian automobile manufacturers have key fob programming protocols with thirdparty companies that make the tools that locksmiths use to programme keys for their customers While some of the aftermarket key fobs are marketed as being compatible with any vehicle most automotive locksmiths dont recommend using them as theyre likely to work poorly or not at all Instead they suggest purchasing fobs specifically designed for your specific vehicle so that you can be certain theyll work properly and are less prone to issues such as interfering or incompatibility This will save you
