Jenkins, who worked for the likes of Crewe Alexandra and Blackpool before joining the Saddlers, took up the role after Keates revealed his desire to build a scouting network which will include several of the club's former pro's.
Before Keates' arrival the club had operated without any recognised scouting system, often relying on word of mouth along with manager and coaches watching matches when the Saddlers weren't in action.
Speaking via the Express & Star, Dean said; "Gary has worked a lot in non-league, he then got an opportunity at Crewe and then he left them to work for Blackpool. I’ve seen him out and about many times. When I got the job here, I saw him at a lot of League One games.
"Bringing him in is something we needed to do. He is Oldbury-based. He knows what the football club is about and what it means to the town and the area. And he is eager, enthusiastic and wants to learn.
"For what we want to do going forward, he will play a massive part. He’s out all the time watching games and now it’s just a case of us all working to a routine, getting some structure and all pulling together for the good of the football club."
