The 36-year-old beauty retreated from the spotlight following her terrifying ordeal in Paris last October and so filming the show forced her back into "getting up and running", and the 61-year-old matriarch also thinks having her daughter speak about the incident on camera helped her work through her feelings.
Kris said: "When we started filming again and getting up and running, you know obviously Kim was around because we all practically live together on the street. And we started filming and what was coming out of that was very therapeutic for her, I think. To just explain to us and walk us through."
Because of what happened to Kim - who has children North, three, and Saint, 14 months, with husband Kanye West - Kris admitted the entire family have made huge changes to their lives and grown more security-conscious.
She added: "She just thinks that it might bring some awareness.
"You know, it's changed the way we live our lives and just the way we take care of our kids and our grandchildren. So it's been a process.
"I locked all the doors and changed the locks cause I'm afraid."
A trailer for the upcoming series of 'KUWTK' features Kim discussing the robbery for the first time, and Kris admitted she found the footage too "upsetting" to watch back, and even now she wants to cry whenever she thinks about what happened to her daughter.
She told talk show host Ellen DeGeneres: "I was watching it and I was balling - balling when I saw it. "And I just saw some of it. I couldn't even watch the whole thing it was so upsetting. It was such an upsetting time and something so awful happened to somebody you love so much. And it's just like it chokes me up every time to think about it.
"No one can get through the first few minutes without getting hysterical. Like, I get choked up just thinking about it and talking about it. But its remarkable to listen to her tell the story and she does that . moment by moment."
