The settlement is located near the point where the course of the Kamchatka River turns from north to east.
History
It was founded in 1731. In 1951, it was granted urban-type settlement status and in 1979—town status. In 2004, it was demoted to a rural locality in order to become eligible for increased funding from the Russian federal budget.
Military
Klyuchi, being in a very isolated part of the former Soviet Union, has been near an intercontinental ballistic missile testing range since the Cold War, the Kura Missile Test Range, and is served by Klyuchi air base just southwest of the town. Klyuchi's original airfield consisted of a dirt airstrip and was located 13 kilometres (8 mi) east-southeast of the town. It was abandoned in the 1960s[4] and is being reclaimed by forest.
Transportation
There is a road connecting Klyuchi to Petropavlovsk-Kamchatskiy. Driving, according to Google Maps, can take as long as several hours.
Climate
Klyuchi has a typical subarctic climate (Köppen climate classificationDfc), albeit with slight early dry-summer precipitation patterns. Summers are generally mild and rainy with cool nights, while winters are long, cold, and very snowy. Due to Klyuchi being located in the interior, the maritime influence is less than for Petropavlovsk-Kamchatsky and the nearest coastal locality of Ust-Kamchatsk.
