How to Replace the Battery in a Renault Megane Key

Model: Renault Megane Megane 2 - Years 2002-2010
Part: Key

To carry out this simple task, you will only need a small amount of patience. First, press the small button at the top of the key on the narrower side to extract the metal key from the upper part of the fob. Now, remove the circular cover that conceals the battery slot. You can use the key itself to help with this. Once the cover is removed, take out the exhausted battery and replace it with a new one, retracing the steps for reassembly.
