Understanding the Renault Laguna Cardkey System

Before diving into the replacement procedure, it helps to understand how the system works. The Renault Laguna (primarily the Laguna II and Laguna III generations) utilized a transponder-based cardkey system rather than a standard metal key and ignition barrel.
