How do you keep players locked in their seats?

Is there any code anyone can send me to keep my players in their seat for a specific amount of time and then when I chose they can jump out their seat?

We can use Humanoid:SetStateEnabled and Seat:GetPropertyChangedSignal to achieve this.

local seat = path.to.Seat -- please change path.to.seat to your seat, HAS TO BE A Seat Instance
seat:GetPropertyChangedSignal("Occupant"):Connect(function() -- get the event signal and connect it to the function
    local occupant = seat.Occupant -- get the humanoid of the occupant!!
    if occupant then -- if there is a occupant
        local p = game:GetService("Players"):GetPlayerFromCharacter(occupant.Parent) -- get the player from the parent of humanoid
        if p then -- if there is a player then
            occupant:SetStateEnabled(Enum.HumanoidStateType.Jump, false) -- disable jumping.
            wait(0) -- change 0 to your time you want to wait.
            occupant:SetStateEnabled(Enum.HumanoidStateType.Jump, true) -- enable jumping
        end
    end
end)

Please mark this as a solution if this works in your context, Metatable out!

Name= "Put in Username" game.Workspace:FindFirstChild(Name).Humanoid.UseJumpPower=false game.Workspace:FindFirstChild(Name).Humanoid.JumpHeight=0 wait(5) game.Workspace:FindFirstChild(Name).Humanoid.UseJumpPower=true game.Workspace:FindFirstChild(Name).Humanoid.JumpHeight= Your Original JumpHeight you have to change the script to make it do what you said.

what this script does: it disables the JumpPower (The Player has to be seated) and then after 5 Sek it Turns it on Again.
