Replacing the Key Battery on Peugeot 308 mk2

Model: Peugeot 308 T9, MK 2 - Years 2013-2021
Part: Key

Replacing the remote battery in your Peugeot 308 is very simple. Open the key using the metal button to eject the metal key. With a flat object, such as a plastic card, remove the cover from the side of the Peugeot logo. Once removed, you will immediately see the compartment where the battery is located. Replace it with a 3V CR2032 battery and check if it works correctly.
