Self storage security levels are easier to act on as a ladder than as a checklist. A facility is rarely "secure" or "insecure" — it sits at a tier, and the useful questions are which tier you're on and what it takes to climb. This guide sets out three: Good, Better, and Best, defined not by how much you spend but by what each tier actually removes as a risk. There's a twist at the top that most grading skips. Moving from Good to Better is about adding protection you're missin

Are there app-controlled storage unit locks? Yes — and a phone can open one four different ways: Bluetooth, WiFi/platform, cellular, and battery-free NFC. Most run on a battery inside the lock, and several charge a recurring subscription fee. One category does neither. This guide lays out all four for self storage, gives you the comparison table nobody else publishes, and answers what using one from an iPhone actually feels like. We build battery-free NFC locks, so we have a

The most useful fact about DaVinci Lock comes from DaVinci itself: "The DaVinci Lock® is not a smart lock nor does it require wifi or power to use" (DaVinci Lock Help Center). That single sentence resolves most of the confusion around the product — and it is the right starting point for anyone comparing self-storage lock systems. This guide covers what the system actually is, what it costs in 2026, and the one architectural question that decides whether it fits your operation

The short answer almost every guide gives — "buy a disc lock" — is correct, and it is also where most guides stop. A disc lock earns its reputation because its shackle is buried inside the lock body, leaving bolt cutters almost nothing to bite (Extra Space Storage). What the advice rarely tells you is how to judge one disc lock against another, which security claims are verifiable, and which part of your door is the real weak point. I design lock bodies for a living, so this

The purchase price of a smart lock is usually the smallest number in its story. Smart lock total cost of ownership is a ledger — hardware, installation, parts, labor, emergency response, administration — and the power architecture you choose decides which of those lines exist at all. Most published cost content stops at "consider various factors." This article computes instead: a line-item ledger, a five-year worked example for a 100-lock deployment, and every assumption stat

An NFC lock is an electronic lock that authenticates users through near-field communication (NFC) — a short-range wireless standard operating at 13.56 MHz over a range of roughly 4 cm (ISO/IEC 18092 and NFC Forum standards). Tap an NFC-enabled phone or card against the lock, the credential is verified, and the mechanism opens. Some designs go further: they carry no battery at all, drawing their operating power from the phone's NFC field itself. A lock with no battery, no wiri
