58 Eiruvin 10/9-12

(9) A man may not stand in a private domain and [use a key] to open [a door] in the public domain, [nor may he stand] in the public domain, and [use a key] to open [a door] in a private domain, unless he has previously made a mechitza [legal partition] ten tefachim high [around the spot on which he stands] - so says Rabbi Meir. [The Sages] said [back] to him, it so happened in the stall-feeders’ market in Jerusalem, that they would lock up [their shops], and place the key in the window [opening] above the opening [doorway]." Rabbi Yose says, "It was in the wool-market."

(10) If there is a loose bolt, with a knob to it, Rabbi Eliezer forbids [one to use it to lock the door of a building on Shabbat]: but Rabbi Yose permits [it]. Rabbi Eliezer said, "It happened in the synagogue in Tiberias that they were accustomed to [treat] it as permitted, until Rabban Gamliel and the elders came and forbade [it] to them." Rabbi Yose said, "[On the contrary;] as forbidden they were accustomed to [treat] it , until Rabban Gamliel and the elders came and permitted [it] to them."

(11) If there is a loose bolt that [is fastened to a rope and part of it] drags [on the ground], we may [use it to] lock [a door] in the Temple, but not in the [rest of the] country; but a bolt that rests [completely on the floor] is forbidden in either place. Rabbi Yehuda says, "[Even] one that rests is permitted in the Temple, and one that drags [is permitted also] in the [rest of the] country."

(12) We may refasten the lower hinge [of a door] in the Temple, but not in the [rest of the] country; but [to refasten] the upper [hinge] is forbidden in either place. Rabbi Yehuda says, "[Even] the upper one [may be refastened] in the Temple, and the lower one [also] in [the rest of the] country."
