How to change touch script to a keybind?

local Services = {
    Players = game:GetService("Players"),
    Debris = game:GetService("Debris")

}
local Settings = {
    Kick_Cooldown = 1,
    Kick_Force = 20
}
local Ball = script.Parent
local KickSound = Ball:WaitForChild("Kick")
local IgnoreTable = {}

Ball.Touched:Connect(function(Part)
    local Character = Part.Parent
    if not Character then
        return
    end
    local Player = Services.Players:GetPlayerFromCharacter(Character)
    local Humanoid = Character:FindFirstChildOfClass("Humanoid")
    local Root = Character:FindFirstChild("HumanoidRootPart")
    if not Player or not Humanoid or Humanoid.Health <= 0 or not Root or table.find(IgnoreTable, Player) then
        return
    end
    table.insert(IgnoreTable, Player)
    delay(Settings.Kick_Cooldown, function()
        if not Player then
            return
        end
        local Position = table.find(IgnoreTable, Player)
        if not Position then
            return
        end
        table.remove(IgnoreTable, Position)
    end)
    local Direction = CFrame.lookAt(Root.Position, Ball.Position).LookVector
    if Direction.Magnitude < 0.001 then
        return
    end
    local Velocity = Instance.new("BodyVelocity")
    Velocity.Parent = Ball
    Velocity.MaxForce = Vector3.new(1, 1, 1) * math.huge
    Velocity.Velocity = (Direction.Unit * Settings.Kick_Force) + Vector3.new(0, Settings.Kick_Force /1.05, 0)
    Services.Debris:AddItem(Velocity, 0.2)
    KickSound:Play()
end)

well to do this, you will need a LocalScript, a remote event, and a normal script to handle it.

firstly, In the LocalScript, you will want to get the UserInputService(you can put this in PlayerScripts):

local UIS = game:GetService("UserInputService")
local remote = --the path to the remote event(should probably put in replicate storage)

UIS.InputBegan:Connect(function(input, processed)

if input.KeyCode == Enum.KeyCode.A and not processed then

remote:FireServer()


end




end)

Then in normal script, put th code in the event:

local remote = -- the path to the remote event


remote.OnServerEvent:Connect(function(player)
-- the code from the ball


end)

-- sorry, im in a rush to do something, tell me if u still have any problems
