Two weeks ago, Kean claimed they were "24 hours'' away from wrapping up a new deal for the youngster, whose current agreement expires at the end of the season.
Progress has been slow since then but Kean, who celebrated his first win of the season with a 4-3 reverse of Arsenal on Saturday, is adamant that Hoilett will sign on the dotted line soon.
"We are getting there very slowly,'' Kean said. "I believe the term has been agreed and his base salary has been agreed. It is the smaller detail which can be slow but the main things have been agreed.''
Hoilett has been at Rovers since he was 14 and has emerged as one of the club's leading players in the last 12 months. He enjoyed an impressive end to last season and Kean is eager to ensure the 21-year-old is tied down to a long contract so he will not leave next summer.
