Jenny @ CRAFT points us to a tutorial on Zakka Life for using a pill bottle, a rock, and some glue to make a stealth key hider for outside your home.

    This is one of those hacks that stops working as soon as it’s posted :)

    Gee, if I were looking for a key hidden under a rock but instead I find a container of some sort, I wonder what might be in the container. Would I leave it untouched or open it and see?

  • Jeremy P

    It’d probably be a better idea to cover the bottle with soil, and only use the rock to mark the spot. That way if someone picks it up, they (shouldn’t) see it.

    Or you could just have a big rock garden with hundreds of rocks to choose from.

  • Victor

    Just make sure you shine up one of those rocks so it’s obvious which one to choose.

    What all the other commenters said. Except I like BigD145’s take on it. THAT is innovation.

  • Jeff

    I don’t think this would work so well when the rock is buried under three feet of snow!

  • Wilson!

    Obvious solution for you is to move someplace warm!

  • Dan

    unless you get overrun with dung beetles.

    Although the hiding of a spare key is practical, hiding it under a rock is just so common place that would be one of the first places to look.

    Depending on your home’s layout, you could hide the key to your front door near your homes back door and vice versa. Or basically, don’t hide the key near the door.

    When hiding your key, you don’t actually have to hide it near the door it opens. All that really matters is that the key is hidden and you can remember where you put it.
