Key not working on "Royal Kludge" mechanical bluetooth keyboard.

I ended up picking up a bluetooth mechanical keyboard around 7 years ago. I've just dug it up again and I've realised that the bottom left "Ctrl" key is not working. What are my options for fixing it? I can easily take off the key caps and access the switches, but is there anything that can be done? Is there any chance reseating the switch will fix it?Thanks
