Kechinov was born in Uzbekistan and started his professional career at local Pakhtakor, with whom he won the Uzbek League title, before moving to Moscow.

With Spartak, Kechinov won six Russian Premier League titles and one Cup.

Kechinov wasn't the only player to have problems with the Spartak management at that time, earlier other star players such as Ilia Tsymbalar, Andrey Tikhonov, Sergey Yuran, Ramiz Mamedov and Evgeniy Bushmanov were forced to leave the team for similar reasons.

After a brief spell at Saturn, Kechinov moved to Shinnik, where he spent the next three years of his career, until retiring in 2004.

He worked as Spartak Moscow reserve coach in 2006–2008, assisting Miroslav Romaschenko.
