Introduction / Context:
This word puzzle asks you to think about objects that have "keys" but no locks. In everyday language, the word "key" usually makes us think of metal keys that open locks on doors, cupboards, or vehicles. However, "key" also refers to buttons arranged on a board, such as those on musical instruments or typing devices. The riddle plays on these two meanings and tests whether you can identify familiar objects where "keys" exist without any associated locks.
Given Data / Assumptions:
- The riddle mentions "keys" but explicitly says there are no locks involved.
- The options list a piano, a computer keyboard, a typewriter, and "All of the above".
- All of these devices actually have physical keys as buttons.
- None of them contains locks in the ordinary sense related to doors or padlocks.
- The puzzle appears in a word puzzles category, emphasising word meanings and double senses.
Concept / Approach:
The central concept is the double meaning of the word "key". On a piano, the white and black keys are pressed to produce musical notes. On a computer keyboard and on a typewriter, keys are pressed to input characters or commands. These are all legitimate "keys" even though they are not used to unlock locks. The riddle does not restrict us to a single example; it simply asks what has keys but no locks. Because all three items fit this description, the best answer among the options is "All of the above".
Step-by-Step Solution:
Step 1: Recall that pianos have keys that you press to create different musical sounds.
Step 2: Notice that a piano does not have door locks associated with these keys; they are purely for music.
Step 3: Consider a computer keyboard. It is full of keys (letter keys, number keys, function keys), and none of them opens physical locks.
Step 4: Think about a typewriter, which has a very similar set of keys used to strike letters onto paper.
Step 5: Recognise that each of the individual options (piano, keyboard, typewriter) satisfies the riddle's description.
Step 6: Since multiple listed options are correct, choose "All of the above" to represent them together.
Verification / Alternative check:
To verify, you can test the riddle with each object separately: "A piano has keys but no locks", "A computer keyboard has keys but no locks", "A typewriter has keys but no locks." Each statement is clearly true in ordinary English usage. There is no need to restrict the answer to just one of them. The presence of "All of the above" as a choice signals that the question designer intended more than one device to qualify. This makes the combined option the most accurate answer.
Why Other Options Are Wrong (by themselves):
Choosing only "A piano", only "A computer keyboard", or only "A typewriter" would ignore the fact that the other listed devices also meet the conditions of the riddle. While each of them individually fits the phrase "has keys but no locks", the multiple choice question structure suggests that the most complete answer is the one that recognises all correct cases. Therefore, the single item options are incomplete rather than strictly false, and "All of the above" is the best match.
Common Pitfalls:
Some solvers may automatically think of the most traditional version of this riddle, where the expected answer is just "A piano". Others may focus on modern technology and jump to "A computer keyboard". The main pitfall is forgetting that multiple choice questions often include an "All of the above" option precisely when more than one item qualifies. To avoid this mistake, always test every option against the riddle and then see whether a combined option better reflects the full set of correct examples.
Final Answer:
All three listed devices fit the description, so the correct answer is
All of the above.
