Mazda: how to replace the remote control battery in a few steps.

Model: Mazda 2 MK 3, DJ - Years 2014-2023
Part: Key

To replace the battery in the Mazda remote, work with the key on a stable surface. First, extract the emergency mechanical key from the remote using the release slider on the casing. Then locate the side opening slot and insert a small flathead screwdriver (or a plastic lever), making a slight rotation to separate the two halves of the remote without forcing the clips. Once open, carefully remove the old button cell and check the code printed on the battery to purchase the same equivalent model. Insert the new battery, respecting the polarity indicated in the compartment (usually with the “+” side facing up), ensuring that it is securely seated in the clips. Close the two parts of the remote by pressing along the perimeter until all the clips snap back into place, then reinsert the mechanical key. Finally, test the buttons and the central locking/unlocking: if the Mazda remote responds correctly, the replacement is complete.

To bleed the clutch on a Renault Clio, open the bonnet to access the components located in the engine bay: here, you will need to undo the screws that secure the battery in its housing, the intake manifold, and the coolant reservoir. This will allow you to locate the pipe through which the brake fluid flows: by inserting the other end of the pipe into a container, you can press the clutch pedal to expel all the fluid until it fills the container.
