These thieves mostly fiddle inside the cabin as shown in the video so I will recommend that even if u have tracker installed do remove/disconnect some pipe , plug or anything else under the hood which only u know which can obstruct the starting of engine or no starting at all.
Thief will be searching for chor switch, electronics under the dashboard and till the time he will figure out something tampered under the hood it will be too late for him.
