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

Yes

The meaning, spelling, and grammar of "teclado" are identical in both Brazilian and Continental Portuguese. The only difference is in pronunciation. In Brazilian Portuguese, the vowels are generally more open and the syllables are articulated more clearly. In Continental Portuguese, unstressed vowels undergo significant reduction; the initial "e" is often pronounced as a very short, nearly silent [ɨ], making the word sound more "compressed" or "swallowed."

Brazilian Portuguese examples:

1. Eu comprei um teclado novo para o meu computador. (I bought a new keyboard for my computer.)
2. O teclado musical está com defeito. (The musical keyboard is defective.)
3. Você pode limpar o teclado para mim? (Can you clean the keyboard for me?)
4. Eu gosto de digitar em teclados mecânicos. (I like typing on mechanical keyboards.)
5. O teclado do meu notebook parou de funcionar. (My laptop keyboard stopped working.)
