Automotive Locksmith Key Programming Modern vehicles require some form of key programming. Depending on the vehicle's make and model, the procedure can be as easy as onboard programming using an extra 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 hardware or software for automotive locksmiths. Transponder Chips Most newer cars use transponder chips to stop car theft. These are tiny computer microchips that emit radio waves at a 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 car doesn't recognise the signal, it will shut down the engine. This technology has proven to be extremely successful in preventing car theft. It also saves many car owners a lot of money because they don't have to replace their vehicles. The transponder system's basic idea is to make it impossible for thieves to open the doors of your vehicle without a valid key. In the past, thieves would simply push your ignition switch to the “on” position with the flat screwdriver, or make use of hot-wires to bypass the system entirely. These types of thefts have been drastically decreased with the introduction of the transponder chip. When you insert the transponder keys into the ignition, the signal is received by an antenna that is concealed around the barrel. The antenna is programmed to detect 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 start the starter. start the engine. Based on the manufacturer, some vehicles will only recognise a specific type of transponder chip.
