In the "Atlas of the Kaluga Governorate" from 1782, a route is mentioned that connected Kozelsk and Bolkhov, passing through Klyuksy, Volosovo, Khryapkino, Veyno, and Verkhny Peredel, heading south. The village of Klyuksy had a ferry crossing over the river. However, after the construction of a mill dam near the village of Bulatovo, the water level in the lower reaches of the river significantly decreased, and the ferry was replaced with a wooden bridge that was built every summer. This road existed for a long time and contributed to the development of riverside and forest villages such as Khostsy, Dubnovichi, Volkovynka, and Volosovo-Zvyagino, located south of the river.

The last owner of the estate in Klyuksy was A.N. Yergolsky. In 1895, the village had five peasant communities. Two of them consisted of former serfs of landowner Sofia Mikhailovna Astafyeva, who later became the schemamonk Sofia and the first abbess of the Shamorodinsky Monastery. One community was made up of the peasants of landowner Shakhnin, another of the peasants of A.N. Yergolsky, and one more from the household of Prince Dmitry Alexandrovich Obolensky, a member of the State Council.

According to the 10th revision of 1858, there were 45 peasant households in Klyuksy, with 213 men and 209 women. By 1895, the number of households had increased to 89, and the population to 272 men and 289 women. There were no local industrialists in Klyuksy, but 37 men were engaged in seasonal work.

To this day, the main house of the estate, built in the classical style, and the remnants of a fruit orchard have survived. The building was constructed in the early or mid-18th century.

During the Great Patriotic War, a military hospital was located in the Klyuksy estate, and later it housed a school. Now the building is vacant and deteriorating.
