Advanced door system for no reason

[exotic tendon]

Can someone help me with my door system which is complicated for no reason

local Functions = require(game.ServerScriptService.Functions)

    local Door = DoorModel:WaitForChild("Door")
    
    local Lock = Door.Lock
    local Locks = Door.Locks

    local DoorSide = side
    local Frame = DoorModel.Frame

    if not originalCFrames[Door] then originalCFrames[Door] = Door:GetPivot() end
    local originalCFrame = originalCFrames[Door]

    local targetCFrame = originalCFrame * CFrame.Angles(0, math.rad(-95aaa), 0)

    if DoorSide == "L" then
        targetCFrame = originalCFrame * CFrame.Angles(0, math.rad(95), 0)
    end

            Functions.RotateDoor(Door, targetCFrame, 0.5)
            IsOpen.Value = true
        else
            Functions.RotateDoor(Door, originalCFrame, 0.5)

prompt.Triggered:Connect(function()

end

return Functions

How it works: It doesnt use tweens instead it rotates the pivot with a "Custom" Lerp rotator also trying to make functionality for locking but it doesnt work
