Review: Reliable, Secure, and Easy to Set Up - This Master Lock key lock box is well built and gives me confidence that my keys are secure.

Review: Solidly made with clear instructions - I was worried that it would not fit my doorknob-older house. It did, but surprise! I couldn’t close my door with the key safe on it. That never crossed my mind, or if I would I be able to close my screen door with the key safe in place. I never did find that out because the second problem was that I couldn’t close the key safe with a key in it. I took it on and off, multiple times, got it working with a key in it and have put it on a different door. I don’t want to fiddle with it now. It’s working and fine where it is. I am not moving it. It’s easy to set or change the combination, and except for getting it to close with a key inside, it has been easy to install/operate. I feel safer with my spare key in this quality Master Key safe. It’s very sturdy and my key is going to be accessible only to me. It’s not going to be easy for a thief to open it. I think my problems closing it were due to me, and not due to any problems with the key safe. ## Features - SPARE KEY STORAGE: This durable key lock box holds up to 5 standard house keys in one locked spot, giving family, renters, and trusted helpers controlled access without hidden spares - WEATHERPROOF OUTDOOR KEY SAFE: A solid metal body and protective shutter door shield the dials from rain, dust, and daily exposure.

It's easy to set and change codes when needed. Good for trusted contractors when you're not at home. It's also saved me a trip when condo tenants lock themselves out, and roommates lose or forget their keys. I was on a cruise last year and needed a neighbor to enter my condo to resolve an issue. I just texted him the code. I wasn't sold on the electronic locks installed on the door itself. If it's an older construction where the door sticks, etc., I was confident that the bolt would always retract properly. This seemed like a very inexpensive and reliable option for me. ## Frequently Bought Together - Master Lock Key Lock Box, Outdoor Lock Box for House Keys, Key Safe with Combination Lock, 5 Key Capacity, 5400EC, Black - Lock Box Buddy - Secure Lock Box Attachment for Lever Handles - Realtors, Vacation Rentals and Real Estate Agent Supplies - Realtor Supplies for Key Lock Box for Keys with Code (1 Pack) - Puroma Key Lock Box, Portable Combination Lockbox Wall-Mounted Key Storage Box for House Keys, Resettable Code Safe Security Lock Box for Home, Office, Apartment Spare Key Storage (1 Pack, Gray) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/2029903-master-lock-portable-key-lock-box-combination-lock-box-holds](https://www.desertcart.sk/products/2029903-master-lock-portable-key-lock-box-combination-lock-box-holds) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-06*
