If you have key fobs for your car you need to secure them

I was talking to our public safety commissioner this weekend, and he told me about it.  I Googled it, and it's a thing.  I have shielded both of my fobs with stuff I purchased off Amazon

Rich: Thanks for the heads-up. I don't see a difference between $6 ones and $15 ones, but figured you already thought of that and researched it... so (continuing in my true spirit of laziness lol) I'm asking (?). Bob

I bought two boxes a few years ago when the entrepreneurs were stealing cars in Northern Bergen County. Actually it's just easier to see which cars are open, because a lot of people keep their fobs in the cars. I get ring alerts all the time about that.

If you want to be cheap tin foil or a metal box will do.  Unfortunately, items this minor don't have reviews, so you sort of have to take it on faith that they are effective.  If I had to guess, I would think most work, but that doesn't mean some shady company might sell one minus the metal shielding.
