Well, I have 2 huge Craftsman boxes full of nothing but Craftsman tools plus a Craftsman roll-around work table full of Craftsman tools - I could run a business out of my garage! & if I do find a need for something I don't have, I go buy it!
My insurance company has looked my garage over, knows what's in it & says everything is either covered by my homeowner's policy, my under restoration car policies (yep, very inexpensive policy that covers disasters in the garage while the cars are in non-running status) or my roadworthy car policies....against theft, fire, etc.
Do my locks work? Yes.
Do I use them? No.
Do I know where all the keys are? Yes.
Will I start using them? Probably not.
Would I try to influence anybody else? No.
