Automotive Locksmith Key Programming Modern cars require some type of key programming. Based on the car's make and model, the process can be as easy as programming onboard using a spare working key or as complicated as OBD2 or EEPROM programming. Most US and Asian auto manufacturers use the same programming protocols as auto tool makers, which means they can develop tools or hardware for locksmiths in the automotive industry. Transponder Chips Most modern cars are equipped with what are called transponder chips to prevent car theft. These are small computer microchips that emit low-level radio signals. They are equipped with a unique digital serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your car isn't able to recognize the signal it will shut down the engine. This technology has proved to be an immense success in stopping auto theft. It has also saved many car owners a significant amount of money because they don't have to replace their vehicles. The basic idea behind the transponder system is to make it impossible for thieves to open the doors of your vehicle without a valid key. In the past, thieves would simply force your car's ignition switch into the “on” position using a flat screwdriver or even hot-wire the car to bypass the system entirely. These types of thefts have drastically reduced with the introduction of the transponder chip. When you insert the transponder key in the ignition, the signal is received by an antenna that is hidden within the barrel. The antenna is programmed to match the frequency of the chip inside the key. The computer onboard of the car will then recognise the key as valid and will allow fuel flow, power the starter or start the engine. Certain vehicles only recognize a specific type of transponder chip, depending on the manufacturer. please click for source is therefore essential that your automotive locksmith is equipped with the correct equipment to program your car's keys and remotes.

If you replace your keys, you'll need to program the new key fob into the car to allow it to function. The most common way to accomplish this is using a car key programming tool that is compatible with the model of the vehicle. This tool allows locksmiths to connect to the OBD port of the vehicle, and then enter the programming mode. The key programming device could be a handheld device that's affordable or sophisticated and capable of doing more than just programming keys (like reading the eeprom file inside the ECU).

It is more complicated and requires a deep understanding of how electronic systems function. This is why it's best left to a professional that has a lot of experience working on these types of systems. Locksmiths can program keys quickly by using onboard programming.
