Which Surah mentions the return of the keys to the Sacred House of Allah to Banu Shaybah?

Surah An-Nisa' is where the command to return the keys of the Kaaba to Uthman ibn Talhah (may Allah be pleased with him) is found, in Allah's saying: "Indeed, Allah commands you to render trusts to whom they are due" (An-Nisa':58). This verse was revealed after the Prophet (peace be upon him) took the key from Uthman and entered the Kaaba with it on the Day of the Conquest. Then he came out and recited it, after which he called Uthman and handed the key back to him. The verse is general for every trust, as the lesson lies in the generality of the wording, not the specificity of the reason for revelation.
