Best Places to Hide a Spare Key Outside (and Worst Ones!)

Ever Locked Yourself Out? Here’s the Smart Way to Hide a Spare Key

Published: 05-Apr-2025

At some point, we’ve all locked ourselves out.

I’ve done it more than once, and yeah, it’s no fun sitting on the porch waiting for someone with a key.

So, having a spare key hidden outside? Smart move.

But where you hide it can make all the difference between a quick fix… and a break-in waiting to happen.

Best Places to Hide a Spare Key

Here’s what I’ve learned from years of tinkering with home security setups—these are the best and worst places to stash that spare.

1. Inside a Lockbox with a Code

If you’re serious about security, this is the way to go. I keep mine mounted on the side of my house, disguised to look like one of those electric meter boxes.

It’s tough, it’s discreet, and I don’t lose sleep over it.

You can get a regular one, but hiding it from plain sight is a better option.

2. Under a Fake Rock (But Not Right There)

Now, the fake rock trick can work—if you put some thought into it.

Don’t just toss it near your front step like everyone else does. Tuck it in your garden bed, mix it with real stones, and it’ll blend in nicely.

3. In a Locked Shed or Detached Garage

Got a backyard shed? Perfect.

I keep a key taped under a shelf in mine. It’s locked, but not as critical if someone breaks in—and it keeps the key off the radar.

4. Behind a Fence Cap or Loose Vinyl Siding

Here’s a little sneaky one I like: remove the top cap of a fence post or pop off a piece of siding. Just remember where you put it!

I once forgot and spent 20 minutes poking around my fence like a weirdo.

Worst Places to Hide a Spare Key

We covered the best places – how about the worst ones?

1. Under the Doormat

Come on. This is literally the first place anyone checks. I’d rather just leave my door wide open.

2. In the Mailbox or Planter by the Door

It’s way too obvious—and you’re probably reaching into that planter every day. Not subtle.

3. On Top of the Doorframe

Used to work… 30 years ago. These days? It’s like handing the key right to someone.

Quick Tips from Me to You

Ever wonder if it’s even worth hiding a key?

Here’s my take: if you live alone or get locked out easily, yes—but hide it right. Do it wrong, and you’re giving strangers an all-access pass.

Remember:

• Only tell someone you really trust where the key is
• Switch up the hiding spot once in a while
• Or better yet—get a smart lock and skip the spare key altogether
