I have a UK layout physical keyboard, which is almost the same as American's, but my keyboard language is set to Swedish. Because of that, the location of ] is different for me also, BUT I noticed that for the sims games it doesn't discriminate what the actual button does for me.
So while on the UK layout it says ] and in Swedish it says ••, the actual button does the same thing.
So, try pressing the button where ] would be for English keyboards. It's the one directly next to return and second up from the right shift key.
Hope that helps.
