In the following steps, you will learn how to change the batteries in your car remote. For some types of remotes, simply press the button to release the key, creating a small opening to lift the tab. Identify the part of the remote that needs to be removed and, using tweezers or a very thin flathead screwdriver, try to lower the tab; when you hear a slight click, apply a little pressure to remove the battery cover.

If there are no slots or openings on the remote, the operation will be a bit longer and more delicate. First, remove the key by pressing the side button, then take off the silver cap. Get a small flathead screwdriver and gently lift the cover.

Remove the flat battery using the same screwdriver, being careful not to damage the internal parts.
