Yamiry Keypad Smart Door Knob Lock, Yamiry Keyless Entry Digital Lock with Handle, Electronic Code Knob for Front Door, Easy Installation

I wanted a keypad door knob that didn’t require another app or hub, just a reliable code and a solid latch. The Yamiry keypad knob hits that brief. After several weeks on a high-traffic side entry (garage-to-house), it’s proven to be an uncomplicated, well-built keyless solution that trades smart-home flash for predictable, everyday function.

Installation and first setup

This was refreshingly straightforward. I pulled the old knob, dropped in the included latch, and mounted the exterior keypad and indoor knob with a screwdriver. Start to finish was about 15 minutes, including fine-tuning the strike plate for a smooth close. Yamiry includes thin rubber gaskets that sit between the hardware and the door faces; they help avoid scuffing and add a small measure of weather sealing. It’s a thoughtful touch you don’t always see at this price.

Programming took a bit longer the first time, mostly because the sequence is button-driven and you’ll repeat it a few times as you add users. The keypad accepts 4–8 digit codes, up to 20 users, plus single-use guest codes. Once I got the flow, adding and deleting codes was simple enough. If you’re code-heavy, plan five to ten minutes to get everyone set up. Minor gripe: the printed instructions would benefit from larger type and a slightly clearer layout, but the steps themselves are logical.

Build quality and design

This knob is made of aluminum alloy with a matte black finish that feels denser and more premium than I expected. There’s minimal play in the spindle, the buttons don’t rattle, and the latch action is positive. The IP54 rating means dust and splash resistance. Practically speaking, it’s fine for interior or covered exterior use; I wouldn’t mount it on a door that takes direct, driving rain without an overhang, but it’s well-suited to garage, side, and front doors that get typical weather.

Inside, there’s no thumbturn; the interior knob turns freely to open. That took a day to get used to, but it’s actually an advantage for egress—if auto-lock engages, you still exit instantly from inside by turning the knob. From the outside, once locked, it stays locked until a code or key is used.

The keypad is backlit and visible at night. It lights up after the first keypress, not on proximity, so your first touch is blind in a pitch-black entryway. It’s a small trade-off, and the illumination is even and bright once active.

Everyday use

Day to day, the Yamiry lock does exactly what a keypad knob should do: it locks when I want, opens quickly with a code, and doesn’t make me think about batteries or connectivity. The auto-lock feature is the unsung hero. You can set it from 5 to 99 seconds or disable it entirely. For a garage entry that should always latch behind you, 15–30 seconds feels right. On a front door, I prefer 45–60 seconds to give guests time to catch the door. The ability to disable auto-lock is useful for moving days and backyard parties.

Code entry is consistent. Buttons have clear tactile feedback, and the unit rejects sloppy presses rather than guessing, which I prefer for security. One-time guest codes work as advertised; I created a single-use code for a contractor and saw it invalidate after the first entry.

Battery status is handled via a low-battery indicator on the keypad. I haven’t hit that threshold yet, but I tested the behavior—auto-lock and code entry continue working with a low-battery warning, and of course there’s a mechanical key backup. The included keys are standard and duplicable.

Security considerations

A keypad knob is never going to rival a Grade 1 deadbolt, but for many doors it’s the right tool. The Yamiry lock’s security is grounded in convenience-you’ll-actually-use: auto-lock reduces the chance you forget to secure the door; the backlit keypad makes code entry quick in the dark; and the ability to rotate codes or issue a one-time guest code is fundamentally more secure than stashing a spare key.

There’s support for obscured entry, letting you add random digits before or after your real code to mask your fingerprints and shoulder-surfing. It won’t stop a determined attacker with tools, but it addresses the most common risks for household and light commercial use. If this is your primary exterior lock, consider pairing it with a separate deadbolt for full-height door reinforcement.

Notably, there’s no wireless connectivity—no Bluetooth, no Wi‑Fi, no Zigbee. That’s either a security benefit (one less thing to attack remotely) or a limitation (no remote unlock, no logs), depending on your needs. I appreciate the “offline” simplicity here.

Fit and compatibility

The included latch and strike are standard residential fare, and the lock is happiest when you use the provided hardware. If you have a non-standard door—especially a 5-inch backset or an old mortise prep—this won’t be a drop-in replacement. Most modern doors with a 2-3/8" or 2-3/4" backset and a 2-1/8" bore will be fine. If you’re retrofitting an older door, measure before you buy and plan to use the supplied latch, as the square spindle interface may not match aftermarket latches.

Door thickness guidance isn’t printed on the hardware itself, but with typical interior/exterior door thicknesses, fitment was no issue. The included screws cover a reasonable range without bottoming out.

What stood out

• Setup speed: Install in a quarter hour with basic tools; programming the first handful of codes is quick once you know the steps.
• Solid feel: Aluminum alloy body, clean machining, and a latch that doesn’t feel toy-like.
• Thoughtful basics: Backlit keypad, adjustable auto-lock, mechanical key backup, and weather resistance adequate for covered outdoor use.
• Code management: Up to 20 user codes plus one-time codes covers families, cleaners, sitters, and trades.
• No app required: It just works, without another account to maintain.

Where it could improve

• Documentation: The programming section could be laid out more clearly and printed in a larger font.
• Keypad wake: It lights after the first keypress. A proximity or touch-to-wake would make the first digit easier to hit in total darkness.
• No remote features: If you want phone alerts, lock status, or integration with smart home routines, this isn’t the right product.
• Hardware interchangeability: It’s designed around its own latch. If you need a 5-inch backset or to reuse an existing latch, compatibility will be limited.

Tips for best results

• Set auto-lock intentionally. Shorter on service entries to avoid forgetfulness; longer on doors where guests linger.
• Use one-time codes for anyone who needs brief access, and regularly rotate permanent codes for household members.
• If mounting on an exterior door, aim for a location with at least partial cover. IP54 handles light weather but not submersion or heavy, wind-driven rain.
• Keep a physical key in a secure spot as a contingency, even with the low-battery indicator.

Who it’s for

The Yamiry keypad knob is ideal for people who want keyless convenience without the overhead of a connected smart lock. It’s a strong fit for garage-to-house doors, side entries, short-term rental interior privacy doors, and any location where issuing and revoking codes is easier than circulating keys. If your priority is smart home control, remote auditing, or integrating with voice assistants, look to a Wi‑Fi/Bluetooth deadbolt instead. If you’re securing a primary exterior door in a high-risk area, pair this with a deadbolt or choose a higher-grade lockset.

Bottom line

The Yamiry keypad knob focuses on the fundamentals and executes them well: solid construction, quick install, straightforward code management, and dependable auto-lock. It avoids the complexity (and attack surface) of wireless features, and it’s priced appropriately for what it does. My only meaningful reservations are documentation polish, lack of proximity wake, and the expectation that you’ll use the included latch—none of which are deal-breakers for a simple, reliable keypad knob.

Recommendation: I recommend this lock for anyone who wants a no-frills, keyless entry that’s easy to install and manage. It’s especially compelling for secondary entries and households that value offline security. If you need remote access, smart home integration, or compatibility with unusual door preps like 5-inch backsets, you’ll want to shop a different category. For straightforward keyless convenience, this is a smart buy.
