How to Replace the Key Battery for Renault and Dacia

Model: Renault Renault Various
Part: Key

In this video, we can see how to change the battery of the key for Renault and Dacia vehicles: on the side with the brand symbol, there is a small slot where you can insert a small flat screwdriver. This will lift the cover, revealing the button battery, a common CR2032 that can be found at any supermarket or electronics store for a few pounds. Remove it, replace it with the new one, ensuring the correct polarity, and then close the cover that was removed earlier. We tested this with a Renault key, but it also works with a Dacia key.
