What is an OBD2 Scanner?

Before we dive into the intricacies of using an OBD2 scanner to unlock your car, let’s take a moment to understand what this remarkable device is. OBD2 stands for On-Board Diagnostics 2, and it’s a standardized system present in most modern vehicles. It’s essentially the car’s way of communicating with you and mechanics by providing crucial information about the vehicle’s health and performance.

An OBD2 scanner is a diagnostic tool that plugs into your car’s OBD2 port, typically located under the dashboard near the steering wheel. It’s capable of reading and interpreting the error codes generated by your car’s onboard computer system. These error codes, also known as Diagnostic Trouble Codes (DTCs), can help you identify issues with your vehicle, including lockout situations.
