It's not a shop, nor a key duplicating cart.
The area where the keysmith resides corresponds to an apartment building.
"This… is too straightforward, isn't it?"
Han Dong and the Clown stand in front of the apartment building, temporarily not stepping into it.
Simply because the hallway is filled with keys... one could even say that the handrails and stairs are all made of keys, with all sorts of keychains embedded in the walls
As if they are directly indicating that the "Keymaker" resides inside.
The clown tried to explore the interior with a Smiling Balloon.
As soon as the balloon flew in.
The key chains embedded in the hallway immediately began to vibrate, and the balloon burst on the spot... the fragments of the balloon had just landed on the surface of a metal gear, and were promptly crushed and swallowed up.
"Interesting Key House..."
Even though the Clown was saying how interesting it is, his body refused to move. He insisted on making Han Dong go ahead.
