Markeyvius Cathey (born August 3, 1997), better known by his stage name Key Glock, is an American rapper from Memphis, Tennessee. A protégé of Memphis rapper Young Dolph, he rose to fame in 2017 for his mixtape Glock Season.
Markeyvius Cathey was born in South Memphis on August 3, 1997. When he was 18 months old, his mother was sent to prison, where she would be for the next 16 years, in both state and federal facilities. His father was in and out of his life, so he was raised by his grandmother. According to Cathey, he and his grandmother visited his mother in prison every now and then. At 18 years old, he was charged with three counts of aggravated assault related to his involvement in a shooting. Fortunately for him, music was a distraction from his hardscrabble life.
Key Glock grew up listening to Gucci Mane and Lil Wayne, and cites Three 6 Mafia as his largest influence. He was also a big fan of Project Pat, whom he describes as the "Drake of Memphis". According to Glock, Pat's songs "If You Ain't From My Hood" and "Gorilla Pimp" changed his life. The latter's chorus inspired one of his breakout songs, "Dig That". The first track that Glock recorded himself was a freestyle of Future's "Ain't No Way Around It" in 2011.
CEO Daddy O and Young Dolph signed Key Glock to the Paper Route Empire label in 2017. On January 25 of that year, Glock released his debut single "Racks Today" featuring American rapper Jay Fizzle. On June 16, 2017, Glock released his debut mixtape, Glock Season, under the label. His collaborative album Dum and Dummer with Young Dolph reached #8 on the Billboard 200 chart. "Major" featuring Key Glock reached #47 on the Hot R&B/Hip-Hop Songs chart.
In mid-2019, following the release of his collaborative album Dum and Dummer with Young Dolph, he went on a European tour across Manchester & London, UK. The pair brought out UK rapper Blade Brown as a supporting act. The two proceeded to start the "No Rules" Tour in 2020, beginning on the 5th Feb in Seattle. On 31st January, Key Glock released his 5th solo mixtape titled "Yellow Tape", which debuted on the Billboard 200 at #13, selling 28,000 album-equivalent units first week. Key Glock has stated that he prefers being an independent artist, as it gives him the freedom to release the type and amount of music he wants to, whilst also keeping majority of his revenue that is generated through streams, touring and album sales. 
Young Dolph is his cousin through marriage.
