The steps to replace the battery in the Renault Kadjar key fob are simple and quick to perform independently. To replace the battery, remove the cover of the fob using a flathead screwdriver.

Once the cover is removed, you can replace the worn battery with a CR 2032 3 Volt battery, which can be purchased online or at auto parts stores. Close the fob cover and test the key's functionality.

If it does not work, you will need to reprogram the fob.
