Merlin Garage Remote Battery Change

Merlin wall mount remotes come with most Merlin openers. If the battery is working, they operate a door with the LED coming on when you press the button. Some remotes have a round button with a smaller circle, while newer models have two square buttons. Both, ultimately, are the same thing.

So how do you change the battery?

This can often seem like a difficult task, as the wall remote will be screwed or taped to a garage or carport wall. Fortunately, it doesn’t have to as difficult as you thought.

Using a flat head screwdriver, you can peel off the front cover from the top part of the plastic case. It should come off easily without breaking any parts.
Be sure to hold on to the front cover as it will peel off as a separate item.
From this point, you can see where the round lithium three volt batteries are located. Use your screwdriver to carefully push them out.
Slide in the new batteries with positive or plus signs up.
Make sure you replace ALL of the batteries (some models have two batteries)
Before placing the front cover back on, test the remote to ensure the batteries are working perfectly by pressing the buttons.
Line up the front cover, make sure that the LED from the back cover is aligned with its hole in the front cover.
Slide the front cover in position, it should clip together with the back cover easily.

Once you’ve done this, you are all finished and have new batteries in your Merlin wall remote. The new batteries should last for a few years before needing replacing again, so take note of when you put them in so that you have a rough idea of when to buy some new batteries again.
