Script:
using UnityEngine;
using System.Collections;

public class changeTool : MonoBehaviour
{
    public GameObject paintTool;
    public GameObject buildTool;
    public GameObject shootTool;

	// Use this for initialization
	void Start ()
    {
        paintTool.SetActive(false);
        buildTool.SetActive(false);
        shootTool.SetActive(true);

	void Update ()
    {
        switchWeapon();  
	}

    void switchWeapon()
    {
        if (Input.GetKeyDown(KeyCode.Alpha1))
            shootTool.SetActive(true);
            buildTool.SetActive(false);
            paintTool.SetActive(false);

        if (Input.GetKeyDown(KeyCode.Alpha2))
            paintTool.SetActive(false);
            buildTool.SetActive(true);
            shootTool.SetActive(false);

            buildTool.SetActive(false);
     }

You’re missing braces around the code you want each “if” block to execute. If you don’t include braces, the “if” will only process a single statement - which is not what you want in this case. Your code should look like this:

void switchWeapon()
{
    if (Input.GetKeyDown(KeyCode.Alpha1))
    {
        shootTool.SetActive(true);
        buildTool.SetActive(false);
        paintTool.SetActive(false);
    }

    if (Input.GetKeyDown(KeyCode.Alpha2))
    {
        paintTool.SetActive(false);
        buildTool.SetActive(true);
        shootTool.SetActive(false);
    }

    if (Input.GetKeyDown(KeyCode.Alpha3))
    {
        shootTool.SetActive(false);
        paintTool.SetActive(true);
        buildTool.SetActive(false);
    }
}
