A Thermometer That Does Double Duty
Most diversion safes are objects you hide among other objects. This one is different — it actually works as the thing it pretends to be. Hang it on a porch, garage wall, or garden post, and it reads the real temperature. Nobody questions a thermometer.
Behind that functional exterior is a compartment that runs the length of the unit, giving you a slim but surprisingly deep hiding spot for spare keys, folded cash, or other small essentials.
Who This Diversion Safe Is For
Homeowners who want a spare key accessible from outside without using the obvious spots. People with workshops, sheds, or detached garages who want a key nearby. Anyone who likes the idea of a diversion safe that actively earns its spot on the wall by actually doing something useful.
The long, narrow compartment also makes it a good fit for small items that don’t work well in round can-style safes — like flat keys or tightly rolled bills.
Is This the Right Choice for You?
Choose the Thermometer Diversion Safe if you want:
- A diversion safe that functions as a real thermometer — dual purpose
- An outdoor-friendly option for porches, garages, sheds, or patios
- A slim, elongated compartment (6″ deep) for keys and flat items
Consider something else if you need:
- A wider compartment for bulkier items — the interior is narrow at 0.875″ wide
- A fully indoor option that blends with kitchen or bathroom items
The Advantage of Functional Concealment
Most diversion safes rely on being overlooked. This one goes a step further — it invites attention by being useful. A thermometer hanging on a porch or garage wall isn’t just ignored; it’s actively accepted as part of the environment. Someone might glance at it to check the temperature and never realize there’s a compartment inside.
The interior measures 1.625 inches wide, 0.875 inches deep, and 6 inches tall. That slender profile accommodates flat keys, rolled bills, a small USB drive, or similarly slim items. The length is the real advantage here — at 6 inches, you have depth that most can-style diversion safes can’t match.
It works indoors too. A thermometer in a mudroom, garage, workshop, or even a kitchen isn’t unusual. Wherever temperature is something people casually check, this fits right in.

Practical Details
Weighs 0.2 lbs. Interior dimensions: 1.625″ x 0.875″ x 6″. Functions as an actual thermometer — no batteries required for the temperature reading. Suitable for indoor or outdoor use. Hangs on any nail, screw, or hook. Simple and maintenance-free.
A diversion safe that doesn’t just hide — it belongs. Functional, discreet, and designed to be exactly what it looks like until you need it to be something more.
Does the thermometer actually work?
Yes. It functions as a real thermometer and displays the current temperature. This is what separates it from most diversion safes — it’s not just mimicking the appearance of a thermometer, it’s actually doing the job. That makes it even less likely to raise suspicion.
What can I fit in the compartment?
The interior is narrow (0.875″ wide) but deep (6″). It’s well-suited for flat keys, tightly rolled bills, small USB drives, or other slim items. It won’t hold bulky jewelry or anything wider than about an inch. Think of it as a purpose-built key and cash holder with length to spare.
Can I use this indoors?
Absolutely. A thermometer in a mudroom, garage, kitchen, or workshop doesn’t look out of place. It works wherever checking the temperature seems reasonable. Outdoors on a porch, patio, or near a garden is the most common placement, but indoor use is equally practical.
How does this compare to a stone hide-a-key?
The stone safe is ground-level and blends into landscaping. The thermometer mounts on a wall and actually functions. The thermometer offers a deeper compartment (6″ vs. 0.75″) but is narrower. If you need something at eye level that earns its place on the wall, the thermometer is the better fit. For tucking into a garden bed, the stone works well.
