I Am Making This Western Game And I Am Trying To Make A Cell Door Open?

So As You Can Tell By The Question.I Am Making A Western Game And If A Sheriff Catches A Theif Or Whatever Then The Sheriff Arrests Them And Tells Them To Come To The Cell.So I Want To make It Simple Instead Of Someone Having To Click It To Open (May Change That) So i Put Can Collide To False And Transparency To 4,But When I Test The Game,The Door Goes Transparent But Doesn't Let Me Walk Into The Cell which Is Meant To Happen When canCollide Is false.

Here It Is:

while true do
    wait(2)
    game.Workspace["Cell Door"].Transparency = 4
    wait(3)
    game.Workspace["Cell Door"].Transparency = 0
    wait(2)
    canCollide = false
    wait(2)
    canCollide = true
    wait(2)
end
