Introduction

Replacing the buttons of the Garmin Vívoactive 4 (M/N: 03618) is a difficult process and requires multiple steps and tools.

If the buttons on your Garmin Vívoactive 4 seem unresponsive and don't operate correctly, it is recommended that you replace the entire housing unit as the buttons will come attached to replacement housing units.

Nonetheless, this guide will take you through the steps required to replace the buttons on your Garmin Vívoactive 4 watch.

This guide requires the use of a heat gun and iOpener. See these articles, How to Use a Heat Gun to Soften Adhesive and iOpener Instructions for instructions and safety information.

    • Flip the watch on its back to reveal the watch band connection pins.

    • Wedge your fingernail or the tip of a spudger underneath the watch band's small metal pin.

    • Push on the pin to release the strap from it's hinge.

    • Pull the strap away from the watch to disconnect it.

    • The strap will not pull away if the pin isn't fully pushed in.

    • With both straps removed, a new replacement watch band may be inserted.

    • Use a heatgun to loosen the adhesive beneath the screen, it should take a 5-10 minutes for adhesive to loosen.

    • Handle the watch with care to avoid burning yourself after it has been heated. Review the How to Use a Heat Gun to Soften Adhesive guide.

    5-10 minutes is too long and too short at the same time. I didn't even heat it for 5 minutes on low and the watch was already too hot to touch. I put on some gloves and tried to wedge my jimmy in between the screen and the case but the seam is much too thin, even when I broke out my knife for it. I thought the glue must not be loose enough yet, so I heated it for a couple more minutes and tried again. Even though I did completely discharge my battery before doing any of this, my battery started to bulge and the back of my watch deformed. I followed these instructions as closely as possible, along with the "how to use a heat gun to soften adhesive" guide, and I never got my screen off and now my watch is beyond reasonable repair. If you decide to try this, I hope you have better luck, but I don't know how you're supposed to be able to get this done.

    • Wedge a thin opening tool or your iFixit Jimmy in between the seam where the screen and the watch’s housing connect.

    • Pry the screen off the device.

    • There is a cable underneath the screen that needs to be disconnected - be careful not to rip it.

    • Work quickly so the adhesive doesn’t cool too much.

    • Use a spudger to pry the battery from the case.

    • Be careful not to damage any surrounding components.

    • There is an adhesive holding the battery down. Use an iOpener if it is too difficult to remove the battery with the spudger alone.

    Where can I get Vivoactive 4S battery from?

    Is this the one and only battery number that is right for 4S or are there others that will work?
