Lockable Storage Boxes

Lockable storage boxes add a welcome layer of security to garden storage. Each lockable storage box in this range is designed to take a lock at the lid, so tools, cushions and children's toys stay where you left them — and garden chemicals stay well away from small hands.

Made from weather-resistant plastic and resin, the boxes stand outside all year without the upkeep timber demands, and closed lids keep the contents dry through the seasons.

Sizes run from compact boxes suited to a balcony or doorstep up to larger garden chests. Check the internal dimensions against what you actually plan to store — cushions in particular eat space faster than you'd expect.

Common questions

Before you buy Lockable Storage Boxes.

How do lockable storage boxes secure their contents?

Each lockable storage box in this range is designed to take a lock at the lid, so tools, cushions and children's toys stay where you left them. Fit a suitable padlock and the closed lid keeps casual hands out. It adds a welcome layer of security to garden storage, turning an ordinary box into somewhere you can leave things with confidence.

Are lockable boxes a safe place for garden chemicals?

They are a sensible choice, since a locked lid keeps garden chemicals well away from small hands. Always store chemicals in their original, sealed containers, keep the box locked when unattended, and position it out of direct afternoon sun to avoid heat build-up. Combined with the lock, that keeps hazardous items secure and stable rather than loose on an open shelf.

What are lockable storage boxes made from?

They are made from weather-resistant plastic and resin, so they stand outside all year without the upkeep timber demands, with no painting, staining or rot to manage. The closed lids keep the contents dry through the seasons as well as secure. That combination of security and low-maintenance weatherproofing is what makes resin the practical material for a lockable box.

What sizes of lockable storage box are available?

Sizes run from compact boxes suited to a balcony or doorstep up to larger garden chests, so there is an option whether you are securing a few tools or a full set of cushions. Check the internal dimensions against what you actually plan to store, as cushions in particular eat space faster than you would expect, then allow a little room to spare.

Does a lockable box keep contents dry as well as secure?

Yes. The weather-resistant plastic and resin construction and closed lids keep the contents dry through the seasons alongside the security the lock provides. To keep it that way, stand the box on level ground so the lid seats correctly, clear any debris from where it closes, and let damp items dry before locking them away.
