Review: Worth the money, works perfectly in a - Have had this for 3 years exposed to weather. Perfect. Slide the cover up or down. Easy to set code. Enough space for 2 keys and my car keys on a fob. No weather leakage and this is Maine with lots of rain and snow. No rust. No malfunctions. Very glad I got it. For a 911 situation is a blessing.
Review: Love pink color - I originally purchased the medium size, but it was larger than I needed, so I returned it. The small size is perfect for holding a couple of keys and fits them easily. Setting up the combination was simple and quick. The lock box feels very sturdy and well made, giving me confidence that my keys are secure. I also chose the pink color, and I absolutely love it—it looks great and is easy to spot. Overall, this was exactly what I was looking for and I highly recommend it.

## Features

- Built-In Hooks On The Back Wall - Interior hooks molded into the back wall hang several keys and a fob so they stay separated and untangled — house key on one, spare or fob on another — and you grab the right key in a second, no digging through a pile.
- Built-In Catch Tray - The fixed interior tray catches keys as the box opens, so nothing jams the mechanism, falls in the dirt or tumbles out when you swing the door — grab what you need in one clean motion, an organizer bargain single-cavity boxes skip.
- Shackle Opens Completely Out - Unlike one-side shackles that drape and slide off, the stainless steel U-arm swings fully open to wrap around a door handle, gate rail, fence post, chain link or padlock hasp, then clicks shut. Clearance 2.25 x 1.5 in.
- Honest About Capacity - The interior is 3.25 H x 3.0 W x 1.4 D in and the rolling-dial mechanism takes up to 1 in of top depth. A 5-key house ring plus one car fob fits and the door still closes; garage remotes and several chunky fobs need the XXL.
- Heavy-Duty Metal Body - Zinc alloy and aluminum construction wrapped in an impact-absorbing polymer shell that takes daily outdoor use and won't mar doors, railings or car handles. Solid, serious protection for your keys — not a flimsy plastic box.
- Built To Stay Outside - A protective dial cover shields the four dials from rain and grit so they stay clean and turn smoothly, and the weather-resistant body handles sun, damp and freeze-thaw year-round — secure key storage, not a burglary-rated safe.
- Set Your Own 4-Digit Code - First open at the factory default 0-0-0-0, hold the inside reset lever, roll in your code from 10,000 combinations, then test it 3 times with the door open before closing. Reset after each handoff so old codes stop working.
- Wall-Mount Hardware Included - Loop the U-shackle on tool-free, or screw it flat with the included 4 screws, 4 anchors and 2 plugs that cap the shackle holes for a clean flush install — no extra trip to the store. Stick-on hanger and guide included.
- Hand Out Access Without Handing Out Keys - Made for real estate agents, Airbnb and VRBO hosts, Turo owners, property managers, cleaners and contractors — plus families who want a spare that can't get locked inside — and never chase a returned key again.
- No App Or Battery - A purely mechanical lock box with nothing to charge, pair or update — no Wi-Fi, no wiring — so it works in cold, heat or a dead-phone moment, the day you get it and years later. Four big dials roll by feel and click into place.
