1. Attach an outdoor socket cover to the wall and stick the key in there instead of an actual electrical plug.
2. Top an empty jar with a drain cover, then bury it in the dirt and pop the key inside.

3. Cover a pill canister with a hose nozzle to disguise it as a sprinkler.
4. Or glue a rock to the top of the pill canister's cap, then sit it in your garden.

5. Glue rare earth magnets to a door knocker so you can pull it off the door with a tug to grab the key out of the back.

6. Spray-paint a big glob of dried hot glue brown to cover a buried jar with fake poo.
7. Or store the key in an empty water shut-off valve, which you can hide under a hose bibb.
