DaVinci Lock: How It Works, What It Costs, and Alternatives
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

Best Locks for Storage Units: What Actually Keeps Yours Shut
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

Smart Lock Battery Replacement at Scale: Why Fleets Fail
At home, smart lock battery replacement is a ten-minute chore twice a year. At two hundred locks, it is a job description. Every battery-life figure published by the industry is a single-lock answer — accurate, and quietly useless to the person responsible for a locker bank, a storage facility, or an apartment portfolio, because nobody multiplies it by N in public. This article does the multiplication. No product pitch, no cost model — just the operational shape of the proble

Smart Lock Total Cost of Ownership: Battery vs Battery-Free
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

Do Smart Locks Work Without WiFi or Power?
Short answer: Most smart locks unlock fine without WiFi — the network exists for management, not for opening the door. Power is the harder question, and the answer depends on which of three jobs inside the lock loses its supply. Vendor pages tend to compress all of this into a reassuring "don't worry," which is exactly why the confusion persists. This article gives you the uncompressed version: a three-layer model of what a smart lock actually needs, a matrix of the four dif

Are NFC Locks Safe? Encryption, Cloning & Relay Attacks
Properly implemented, yes — an NFC lock that pairs AES-256 encryption with challenge-response authentication has no practical wireless attack today. The honest caveat lives in the word implemented. The market spans hardware that never transmits a copyable credential and hardware that announces one fixed ID to anyone who asks, and which end of that spectrum a product sits on decides whether "NFC" means protection or exposure. So instead of the usual "buy from a reputable bran

How NFC Energy Harvesting Powers a Lock Without Batteries
NFC energy harvesting is the process of turning the 13.56 MHz radio field emitted by an NFC device — usually a smartphone — into usable electrical power. Every NFC link is built on inductive coupling between two small antenna coils, and a passive NFC device sitting in that field can do two things at once: exchange data and draw energy (near-field communication standards, ISO/IEC 18092 and ISO/IEC 14443). A battery-free lock pushes the second capability to its logical end. Th

NFC vs RFID vs Bluetooth: Which Lock Technology Wins?
The short answer: NFC is not a competitor to RFID — it is a specialized subset of it. NFC (near field communication) is built on high-frequency RFID at 13.56 MHz, adds two-way communication, and works over roughly 4 cm (ISO/IEC 18092 and related standards). RFID is the broader family, spanning three frequency bands with read ranges from centimeters to ten meters. Bluetooth is a different technology entirely — a battery-dependent radio link designed for continuous connections

What is an NFC lock? How It Works & Why Battery-Free Wins
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
