My battery leaked acid yesterday and after cleaning it up, the calculator worked perfectly. However, today when I went to use it, every key worked except for the enter key. What can I do?

You can try to repair the button using this guide here. However, the corrosion may have permanently damaged the button which will require a motherboard replacement. You can’t buy new motherboards, but if you can find a calculator with damaged screen, the motherboard is still probably OK and you can salvage it out of the broken calculator. There’s a guide on motherboard replacement here.
