Check Price on Amazon

The code-only deadbolt that keeps a curious child out with no app, no Wi-Fi, and no subscription.

Parents who need one specific door to hold firm buy this DESLOC C100 for a simple reason: it has no Wi-Fi, no app, and no subscription. Every setting happens on the lock itself, which means nobody can talk to it remotely and the access data stays stored locally on the unit. The setup that gets repeated in the reviews is quick — buyers report it went on the door in under 15 minutes with no drilling or realignment, and the manual was clear enough to follow without a second pair of hands.

Where this lock beats the Veise VE027-K for the right buyer is capacity at the code level. You can program 100 user PIN codes for family, staff, or tenants, plus 4 one-time codes that expire automatically after a single use. That covers a cleaner, a delivery, or a temporary house guest without ever handing over a working key. The 0.96 inch visible display (a small screen on the lock face that shows what you are typing) is the feature that separates it from most keypad-only deadbolts, because you can see the code entry and the menu instead of guessing whether a button registered. Codes run 6 to 8 digits, and the interface lets you give each one a name so you know whose code is whose.

Security sits at BHMA Grade 3 with a reinforced lock cylinder, an IP54 weatherproof body (a rating that means it handles splashing water from rain or a damp room), and anti-peep PIN protection. Auto-lock is adjustable from 5 to 120 seconds, and the honest trade-off is the one buyers keep raising: it locks even when you step out for ten seconds to grab a parcel, so set the window longer if your door is used for quick trips. Battery life runs up to 12 months on 4 AA cells, and if it ever dies the Type-C emergency power port lets you jump it from any power bank instead of crawling through a window. At 8.11 x 5.91 x 3.98 inches it is the more compact housing of the two against the Veise’s 7.09 x 3.54 x 9.84 inch frame. The small LED text is the only cosmetic complaint, and it is minor.

A keypad knob with Silent Mode that kills every beep for midnight trips.

Bedrooms and bathrooms sit side by side, and that is the whole reason this Veise KS03 exists in the shape it does. Silent Mode shuts off every keypad beep, so a late-night trip to the bathroom stops being a small event. Vacation Mode goes the other way and disables every user code except the master, which is useful for a bathroom door you want sealed while the house sits empty. If neither applies, a simple press and hold on any key for 2 seconds locks the door from outside, and a thumb turn does the same job from inside.

Capacity covers a normal household and a bit more. There is room for up to 20 user codes at 4 to 10 digits each, plus a one-time code and 2 spare keys in the box. Auto-lock runs from 10 to 99 seconds and is on by default, though you can switch it off entirely and use the lock in passage mode during a party or a busy morning. Weather duty is handled by an IP55 rating (sprayed water is fine, so a humid bathroom is no problem) and a rated working range of -35°F to 160°F, which means the same lock survives a cold porch and a hot corridor. Battery life reaches up to 365 days, and the backlit keypad makes the numbers legible in a dark room without fumbling for a light switch.

The one thing to be honest about is how the feel of the keypad divides people. Functionality is the most-discussed topic across the reviews, and it is a mixed bag rather than a clean win — some owners find the keypad response crisp, others find it slow to register. Durability shows up as a genuine weak point for a small number of owners, and one of those units failed to unlatch within a week. Against that, the support team is fast and replaces faulty units without argument, and the build draws consistent praise for quality. Installation takes about 10 minutes with a screwdriver, and the lock fits standard doors 1-3/8 to 2 inches thick. One owner whose grip is limited by arthritic thumbs was initially worried about the fully round knob, and reported no trouble turning it.

Fingerprint entry and app control at the price of a plain keypad deadbolt.

If you want to try fingerprint access without committing to a premium lock, this TEEHO TE012W is the least expensive way onto the list to get it. It connects straight to 2.4GHz Wi-Fi with no hub in the middle, and it works with Alexa and Google Assistant for voice control. There are five ways in: the app, a fingerprint that stores up to 20 users, a passcode pool of up to 100 codes, 2 backup keys, and voice. For a door that a teenager keeps forgetting to lock, the app lock and open up alone is worth the upgrade. The KE Home app also carries AES-128 encryption (a standard scrambling method that protects your access data) and stores that data locally.

Security extras are where the value really shows. Enter 10 wrong PINs and the lock freezes for 3 minutes and pushes a break-in alert to your phone. The anti-peep password lets you pad your real code with random digits on either side, and the backlit keypad keeps it usable at night. The housing is BHMA Grade 3 certified and rated IP55, so a damp hallway or a covered porch is fine. Auto-lock adjusts from 10 to 180 seconds in the app, or you can lock up in 2 seconds with a single touch on the way out. Installation runs 10 to 15 minutes with a screwdriver and no drilling, fitting doors 1-3/8 to 2 inches thick with a 2-3/8 or 2-3/4 inch backset.

The honest catch is power. This lock takes 8 AA batteries, which is twice the cell count of a standard 4-battery Wi-Fi lock, and battery life is the single most-mentioned gripe among owners — a few report swapping batteries sooner than they expected. Set your auto-lock window and keep the Wi-Fi signal strong and it behaves better. Compared with the Veise VE027-K above, this one has the same 8 AA appetite for a fraction of the outlay, but it drops the IP65 shell and the 0.2 second rated fingerprint speed for a slower reader and a lighter build at 0.92 kg.

The smart knob built for the garage-to-house door, the most open up gap in most homes.

The door between the garage and the house is the most open up gap in most homes, and this Veise VE018 is built exactly for that spot. It takes 8 ways in — a 0.2 second fingerprint, app control over Bluetooth, the keypad, an IC card, mechanical keys, remote authorisation, password sharing, and voice through the Veise G1 Gateway (which is the separate bridge you buy to put the lock on your Wi-Fi, since the lock itself only speaks Bluetooth). Two key fobs and two user cards come in the box, so you can hand a card to a family member without handing over the app.

The reader holds up to 20 fingerprints using FPC sensor technology with AI self-learning, rated at 0.2 second recognition and above 99% accuracy. Access logs show exactly which finger opened the door and when, which is more useful than it sounds when someone keeps borrowing a bathroom key. Codes run above 100, split into permanent and recurring options plus remote one-time and duration codes for a house sitter, a cleaner, or a delivery. Anti-peep entry lets you bracket your code with extra digits. The build carries ANSI Grade 3 and BHMA certification, 128-bit AES encryption, local data storage, intrusion alerts after repeated failed attempts, and a 96-hour corrosion resistance test. It works from -35°F to 160°F and includes passage mode and mute mode.

The battery claim is the standout number: 4 AA alkaline cells give up to 16 months of use, which the maker describes as 80% longer than standard smart locks. That is a two-thirds reduction in cell count versus the Veise VE027-K’s 8 AA, in a package that runs measured in years at a bathroom door. There is a Type-C emergency port for temporary open up if the cells do die, plus the backup keys. What owners trust most here is reliability, and it is fair to say the mechanical side is the softer half: a machine-pressed knob has come off for at least one owner, and the internal mechanism can feel stiff, needing a manual turn to set the stop. Owners mention it works well with Google and Alexa once the gateway is installed.

A rental-grade deadbolt with the fingerprint capacity of a small office.

Hosts and landlords get the most out of this Sifely Model O deadbolt because it is built to spread access around. It stores more than 100 fingerprints and more than 100 codes, which is far past what a family needs and squarely aimed at a door that gets handed to guests, kids, seniors, and short-term renters. Entry options are fingerprint, keypad code, app, fob, or a physical key. The free app and web portal let you manage codes, read the activity logs, share eKeys, and set access schedules around who is coming and going. Auto-lock fires after each entry, with a one-touch lock on the # key and privacy and passage modes when you want the door left open.

The build is the strongest signal in the reviews, with quality praised more than anything else. It installs with a screwdriver and no locksmith, fits left and right doors, and customers note it still working like new after months of use. Voice control works through Alexa or Google once a Sifely Gateway (the separate bridge for Wi-Fi) is connected — the lock otherwise talks over Bluetooth. That gateway requirement is the detail worth knowing before you buy if you want to open up that door from somewhere else, and the practical Bluetooth range is around 10 to 12 feet, so you need to be near the door. Also worth knowing: only one device can be signed into the account at a time, so a house with several phones will need to trade turns.

The genuinely mixed part is the hardware behaviour. Some units run flawlessly, others hit a jam when open up, and the fingerprint reader is reliable for most people but occasionally needs a second attempt. A slow wake-up on the lock button is the most common small annoyance, with owners asking for a faster one-button auto-lock. Access methods cover 6.3 x 2.6 x 1.9 inches of housing, and the brass finish is the distinctive look on this list. Under all of it sits the same anti-peep code entry and low battery alerts you would expect, and an occasional unit arrives needing a support call that the company handles promptly.

One box that replaces both the handle and the bolt, in a single screwdriver session.

When the old bathroom handle is loose and the deadbolt above it is a different colour, buying a handle set solves both problems at once, and this TEEHO TK001H is the complete version of that idea. You get a keypad deadbolt, a lever handle, two backup keys, and the latch and strike hardware in one purchase. It fits standard U.S. doors with a 2-1/8 inch bore hole and a 1-3/8 to 2 inch door thickness, and the handle hole is adjustable, so it works on left or right handed doors without new drilling. Reviewers point out the whole thing goes on in around 10 minutes and the code changes just as fast.

Entry options cover the everyday cases well. There are 20 user codes, 2 backup keys, one-time codes that delete themselves after a single use, and passage mode for when you want the door open. Auto-lock is adjustable from 10 to 99 seconds and arrives off by default, which is a smarter default than it sounds — you decide when the door starts locking itself. If you prefer to lock on your way out, press and hold any keypad number for 2 seconds. Anti-peep entry lets you pad your code with extra digits, and 10 wrong attempts triggers an anti-crack lockout. The body is aluminium and zinc alloy, tested to ANSI Grade 3 and rated IP54 for water resistance (splash-safe, so a humid room is fine). Power comes from 4 AA batteries running up to 1 year, with a red low-battery flash once the power drops below 15%.

The most-discussed issue with this set is that a few shoppers say trouble getting out of the house in certain scenarios, which is a fair reason to read the manual on the interior exit before you fit it. Everything else holds up: the appearance reads as more expensive than a plain keypad, the instructions are clear, and the auto-lock behaviour is the top reason people buy it. Support runs 2 years of warranty with lifetime service.

The lock for somebody who refuses to put an app on their phone.

Some people want a code on the door and absolutely nothing else, and this Yale Code deadbolt is the purest version of that idea. It is a non-connected lock — no Wi-Fi, no Bluetooth, no hub, no app. Adding and removing codes, setting up auto-lock, and adjusting the sound all happen on the lock itself and can be finished in seconds. It stores up to 20 entry codes, which is more than enough for a household and the people they trust, and each code can run from 4 to 8 digits so you decide the length. Built quality is what owners talk about most, and the deadbolt has the sturdy feel to match the reputation, with a low-profile design and a matte Black Suede finish that blends into most décor.

The details that make daily use pleasant are small but real. The buttons are raised rather than flat, which one owner called superior to the flat style for finding a digit by touch. The keypad is backlit and the speaker gives a clear chime when somebody open up the door. Auto-lock kicks in after 30 seconds, which is enough to keep the door secure behind you but tight enough that a slower guest might be shut out — set the code entry first, then decide if you want that window. It works on existing doors and installs with minimal fuss; most owners measure their first attempt in minutes rather than hours.

The honest caveats are worth stating plainly. The locking sound is loud enough that one owner flagged it as genuinely noisy. Deleting a code is not obvious without a look at the manual, and the backlight is faint enough to be hard to read in daylight. It also will not work with Alexa or Google, by design. Isolated reports of a unit failing after a couple of months exist, and they are rare. On the value side, this is the entry point into a well-known lock brand, and owners consistently say it feels like a more expensive piece of hardware than it is. Against the TEEHO TK001H, you give up the matching handle set but gain a brand-name deadbolt with no app layer at all.

The heavy one-piece plate that hides every old hole in the door.

If your door already has two holes — one for the bolt and one for the handle — and the finish around them is a mess, this Nyboer solves a cosmetic problem and a security one at the same time. The extra-long 9.25 inch panel covers both the deadbolt and the handle holes in one piece, so there is no patching, no filler, and no exposed gap where the old hardware used to sit. It works with single-hole or double-hole doors and installs with a screwdriver. At 4.3 pounds it is the heaviest unit here, and the weight is noticeable in the door the moment you take it from the start — a substantial piece of hardware rather than a lightweight shell.

Entry is genuinely wide. Fingerprint, keypad, app, key fob, and physical key cover five routes, with remote access and voice control through a Wi-Fi gateway (the separate bridge, required for anything off-site). Fingerprint reads run fast and accurate, using the enrolled finger, and open up in about a second. Push it to the limit and you get 100+ fingerprints, 100+ codes, permanent and scheduled passcodes, an entry log, and app alerts when the battery runs low. Five physical keys and five key fobs come in the box, so a family can hand access around without anyone installing software. Power runs from 4 AA batteries with long life and low-battery app alerts.

App control is the part that makes the upgrade worth it for anyone with guests. You can lock or open up remotely, create temporary or scheduled passcodes, and read the access activity at any time — the practical version of that is a dog sitter getting a code that expires on Sunday. Everything is backed by a 30-day money-back guarantee, a 2-year warranty, and 24/7 customer support. The trade-off compared with the cheaper code-only locks on this list is complexity: more ways in means more setup, and the gateway is a separate purchase if you want remote control. For a bathroom door used only by residents, most of this capability would go unused.
