Automotive Locksmith Key Programming Modern cars require some type of key programming. Depending on your vehicle's model and manufacturer, the process may be as simple as using an additional key to program the onboard computer, or as complex as EEPROM or OBD2 programming. Most US and Asian automakers use the same programming protocols as auto tool makers, which means they can develop tools 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 low-level radio waves. They have a unique serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your vehicle does not recognize the signal it will shut down. This technology has been an enormous success in preventing auto theft. It has also saved many car owners a lot of money as they don't have to replace their vehicles.

In the past, car thieves would use the flat screwdriver to push the ignition switch of your car into “on” mode, or hot-wire it to evade the system. Transponder chips have drastically decreased the likelihood of theft. When you insert the transponder keys in the ignition, the signal is picked up by an antenna that is concealed around the barrel. This antenna is programmed with the frequency of the chip inside the key. The car's onboard computer will recognise that the key is legitimate and allow fuel to flow, power up the starter or start it. Depending on the manufacturer certain vehicles can only recognize the specific type of transponder chip. It is therefore important that your locksmith for cars is equipped with the right equipment to program your keys and remotes for your vehicle.

Instead, they suggest buying fobs specifically designed for your specific vehicle so that you are certain they'll function properly and be less prone to issues like interference or incompatibility.
