If you're ever paranoid about locking yourself out of your house, the worst thing you can do is to hide your spare key in an obvious spot, like under the doormat, under a planter, or anywhere near the front door.
One of the most fool-proof ways to hide your keys is to give a copy to a trusted neighbor, family member, or friend who lives nearby. If that isn't possible, you can hide your spare key on the collar of your backyard dog or underneath a planter or door mat—but on a neighbor's front porch, not yours.
For a more DIY, crafty approach to hiding keys, you can create a decoy hiding place out of a real rock, super glue, and a prescription pill bottle. Simply glue the rock on top of the cap of a prescription bottle, place the key inside the bottle and bury it underground so that only the rock is sticking out.
