How to Replace the Key Card Remote Battery of a Renault Megane 4

Model: Renault Megane Megane 4, Megane IV - Years 2015-2023
Part: Key

This guide shows how to replace the battery of the car remote. First, remove the rear cover of the device, then apply slight pressure on the back of the remote and slide it towards the bottom (in the direction of the hole on the short side of the device). At this point, you can access the internal circuitry. To replace the battery, simply lift the battery cover (a plastic disc) with pressure, and using a small screwdriver, lift out the battery to be replaced. Insert the new battery (model CR2032) and reassemble the battery cover and the remote cover (following the initial procedure in reverse). The operation is now complete.
