Sim — Yes

Não — No

Funciona — It works

Não funciona — It doesn’t work

Funciona sim — It does work (adds reassurance)

Não funciona não — It really doesn’t work (colloquial emphasis)

When you want to be polite or add more information, use these short sentences.

Sim, funciona. — Yes, it works.

Não, não funciona. — No, it doesn’t work.

Está funcionando. — It’s working (right now).

Não está funcionando. — It’s not working.

Deixa eu ver. — Let me see.

Vou tentar outra vez. — I’ll try again.

Responses with instructions or suggestions

If the key doesn’t work, you may need to suggest solutions or next steps. These phrases are useful in practical contexts like hotels, apartments, or offices.

Tente girar mais forte. — Try turning harder.

Tente devagar. — Try slowly.

Eu: A chave funciona?
Vizinho: Não funciona. Está travando.

Hóspede: Essa chave abre o quarto 205?
Recepcionista: Sim, funciona. Aqui está.

Borrowing a key from a friend
Amigo: Toma, pega a chave.
Você: Tudo bem. Funciona?
Amigo: Funciona sim.

More natural, everyday replies

When speaking casually, Brazilians often use short, colloquial phrases. These are safe for informal contexts.

Beleza, abre. — Cool, it opens. (casual)

Tá sussa, funciona. — It’s fine, it works. (very casual)

Não tá pegando. — It’s not catching / working. (colloquial)

Tá emperrado. — It’s jammed.

Explaining why the key doesn’t work

Useful short explanations help you communicate the problem to a landlord, receptionist, or friend.

A chave está torta. — The key is bent.

A fechadura está quebrada. — The lock is broken.

Tem sujeira na fechadura. — There is dirt in the lock.

A porta está inchada. — The door is swollen (common with humidity).

Practical phrases to ask for help or replacement

These are direct but polite ways to request assistance or a new key.

Pode fazer outra chave? — Can you make another key?

Você pode trocar a fechadura? — Can you change the lock?

Posso pegar emprestado uma chave? — Can I borrow a key?

Tem alguém que conserte fechadura? — Is there someone who repairs locks?

Pronunciation tips for beginners

Simple pronunciation reminders make these phrases easier to say.

A chave — pronounce chave like SHA-vee (x sound like sh)

Funciona — pronounce funcio-na like foon-see-OH-nah (soft c before i)

Trancar / destrancar — trahn-KAR / deh-strahn-KAR (stress on last syllable)

Fechadura — feh-sha-DOO-rah (stress on DOO)

Common mistakes to avoid

Beginners often mix verb forms or use literal translations. Watch for these errors.

Saying Eu funciona — incorrect. Use funciona alone for it works, or Ela funciona when referring to a chave.

Using abrir incorrectly — abrir means to open generally; ask Essa chave abre? for clarity, not Abrir a chave.

Confusing trancar and fechar — fechar means to close, trancar means to lock. A chave tranca a porta means the key locks the door.

Overusing formal phrases in casual situations — use Sim / Não / Funciona in informal contexts.

Real-life examples you might use

Imagine you are checking into a short-term rental.

Host: Aqui está a chave do apartamento.
Você: A chave funciona na porta da frente?
Host: Sim, funciona. Se tiver problema, me liga.

At a store selling keys

Você: Essa chave abre este cadeado?
Vendedor: Não, essa é para portas. Aqui está a certa.

Beginner tips for confidence

Keep your replies short and clear. Start with Sim or Não, then add a short phrase like funciona, não funciona, or deixa eu ver. Watch and imitate the stress pattern of verbs (many end stressed on the last syllable). Use gestures if needed: point to the key, the lock, or the door while speaking.

Short checklist before replying

Look at the lock and the key

Try the key slowly once or twice

Listen for clicks or resistance

Use a short phrase to answer
