->''"20 bucks says I can get in in 20 seconds"''
-->-- '''Dr. Gregory House''', '''''Series/{{House}}''''', before performing the trope.

Do you need to get into your house... or perhaps someone else's house... quickly? Have you suddenly realized you locked your keys ''inside'' your house, so that now you not only can't get your car started, but you can't get into your house to get your keys? What do you do? Why, you look under the doormat, of course!

Occasionally, the spare key isn't hidden under the doormat, but is rather hidden inside a fake rock, or in a ceramic animal near the door, or even concealed atop the frame of the door itself. There is also a vehicular variant wherein the spare key is hidden above the driver's side sun visor.

Often TruthInTelevision, despite the advice of pretty much every crime prevention leaflet. Compare WeHaveTheKeys, which often occurs after a door is [[ThereWasADoor destroyed or bypassed]] when a less destructive alternative was available.



* In a commercial for Energizer batteries, Count Dracula, who is hired by the Supervolt battery company to steal the Energizer Bunny's battery, gets locked out of his castle chasing the bunny. He has the key to his castle under his "Velcome" mat, but before he can use it to unlock the door, the morning sun rises, and he says, "[[FamousLastWords Oh... great.]]" before it vanquishes him.

Sure enough, they remove the bum's hat to find the key resting on his scalp. The "bum" turns out to be a dummy.
* Parodied in an episode of Series/{{Chucklevision}} where the duo are delivering and installing a heavy fireplace. They look under the mat and can't find a key so they assume they got the apartment number wrong when they find a key under the other mat. It turns out the instruction was look under the "cat" as in a little porcelain cat so it turns out they've been renovating (read: wrecking) the wrong place.
* Also parodied on the absurdist show ''Series/StellaUS'', where Michael, Michael & David explain to the landlord that their spare key is kept under the doormat, but it's off at the cleaners and he'll need to go pick it up from there.

They also point out how much easier it made it for the unsub to get close to her, though he didn't use it to abduct her.
* In ''Series/{{Supergirl}}'', Superman leaves the key to the Fortress of Solitude right in front of the door. It gets covered with snow, considering where it is, but he doesn't even bother with a mat.

* On ''Radio/APrairieHomeCompanion'', there's a fictional inventor that attempts to avert this. He sells Cowpie Key Hiders.

So instead of putting your key under the mat like an idiot, you can put it where nobody wants to look.
* In the Radio Drama ''The Father Gilbert Mysteries'' "Where The Heart Is", Mr. Eckhart concludes that someone broke into the church's crypt by using the key hidden under the flower pot beside the door. Father Gilbert chews him out for keeping a key there, as it's the first place anyone would look.
* Similarly in ''Radio/AdventuresInOdyssey'' Connie jumps from tree to ledge to window in order to get into Mitch's apartment. Mitch tells her that she could have just used the key under the mat. A rather unsafe place for an FBIAgent to hide a key though...
