Is the word fechado the same in Brazilian and European Portuguese?

Yes

Explanation The only differences between "fechado" in Brazilian Portuguese and Continental Portuguese are pronunciation. Brazilian Portuguese tends to have more open vowels and a more melodic, rhythmic cadence. In Continental Portuguese, unstressed vowels (like the "e" in fechado) are often reduced or "swallowed," making the word sound more clipped or muffled to a Brazilian ear. There are no differences in spelling, grammar, or the fundamental meaning of the word.
