Evanshow's 1.2 lb knob wins for hollow bedroom doors. - Author: Taylor Davidson - Tags: Tools & Home Improvement, Smart Home, Door Hardware The best lightweight fingerprint smart lock for most bedroom and rental doors is the Evanshow Biometric Door Knob at 1.2 lb, with a 1.18-1.97 in door thickness range and no drilling. It replaces a standard knob in minutes. For a front door where you want Wi-Fi, auto-lock and a USB-C emergency port, the Wyze Auto-Lock Bolt v2 is the better call, though at 3.25 lb it is nearly three times heavier and needs a deadbolt cutout.

[FAQ](#faq) ## How I cut the field to seven Most "fingerprint lock" searches return a swamp of near-identical listings. My screen started at roughly forty candidates in the Door Hardware and Biometrics categories on Amazon, then cut anything without a published fingerprint capacity, anything missing dimensions, and anything with no listed model number. That knocked out the majority. From the survivors, I kept a spread across three shapes buyers actually pick between: light knob replacements for interior doors, mid-weight handle locks with keypads for entry doors, and full deadbolts for front doors. That gave me the seven picks here. A note on the search term. Amazon's results for the phrase are only partly filtered by weight; several products it returns weigh over three pounds. That means the qualifier is a preference, not a hard promise from the retailer. Where a lock has a published weight, I quote it. Where it does not, I flag it, because a lightweight fingerprint smart lock claim without a number on the scale is a claim you cannot verify. Treat unlisted weights as a real gap, not a rounding error. ## Best lightweight fingerprint smart lock at a glance | Pick | Weight | Unlock methods | Price | | --------------------------------------------------------------------------------------------------------- | ---------- | ------------------------------------------ | ------------------------------------------------------------------ | | **Best overall**[Evanshow Fingerprint Door Knob](https://www.amazon.com/dp/B0F375TD2P?tag=dieless-20) | 1.2 lb | Fingerprint, code, IC card, key | [Check Price](https://www.amazon.com/dp/B0F375TD2P?tag=dieless-20) | | **Runner-up**[GHome Smart Fingerprint Door Lock](https://www.amazon.com/dp/B0DHS46L2F?tag=dieless-20) | 1.65 lb | Fingerprint, code, app, key | [Check Price](https://www.amazon.com/dp/B0DHS46L2F?tag=dieless-20) | | **Best warranty**[KLLOQUE Fingerprint Door Lock](https://www.amazon.com/dp/B0D1BR28N8?tag=dieless-20) | 1.63 lb | Fingerprint, code, key | [Check Price](https://www.amazon.com/dp/B0D1BR28N8?tag=dieless-20) | | **Best minimal setup**[Yamiry Fingerprint Knob YR01](https://www.amazon.com/dp/B0C66NCTXX?tag=dieless-20) | Not listed | Fingerprint, code, app, key (6-in-1 claim) | [Check Price](https://www.amazon.com/dp/B0C66NCTXX?tag=dieless-20) | | **Best upgrade**[Wyze Auto-Lock Bolt v2](https://www.amazon.com/dp/B0FD3WMV2T?tag=dieless-20) | 3.25 lb | Fingerprint, code, Wi-Fi app, key | [Check Price](https://www.amazon.com/dp/B0FD3WMV2T?tag=dieless-20) | | **Best for pros**[Yamiry Handle Lock YR05](https://www.amazon.com/dp/B0DGQ8HCVB?tag=dieless-20) | 2.6 lb | Fingerprint, code, app, key fob, key | [Check Price](https://www.amazon.com/dp/B0DGQ8HCVB?tag=dieless-20) | | **Best premium**[eufy Security Smart Lock C220](https://www.amazon.com/dp/B0C7C69FPS?tag=dieless-20) | Not listed | Fingerprint, code, Wi-Fi app, HomeKit, key | [Check Price](https://www.amazon.com/dp/B0C7C69FPS?tag=dieless-20) | ## Why weight matters more than you think Weight is the single spec that quietly decides whether a fingerprint lock survives on your door. Hollow interior doors, common on bedrooms and rental apartments, are typically two thin skins glued around a cardboard honeycomb. Hang three pounds of aluminum and battery pack off that, on a knob-sized bore, and the sag pulls the strike out of alignment within weeks. That is why the winner here is a 1.2 lb knob, not a 3.25 lb deadbolt. On a solid-core exterior door, weight barely matters. On a hollow bedroom door, it is the whole game. Two of the seven locks here do not publish a weight at all. That is a genuine gap, not a rounding error, and it is worth writing to the seller before you buy if the door is a light one. ## Knob or deadbolt: which suits your door? Look at the door before you look at the lock. If there is only a knob and no separate deadbolt cutout above it, you want a knob replacement, which is four of the seven picks. If there is a deadbolt cutout, a deadbolt gives you more security and, in the case of the Wyze and eufy here, Wi-Fi. - **Knob only, hollow door:** Evanshow, KLLOQUE or GHome. Under 1.7 lb, drop-in fit. - **Handle-and-latch, no separate deadbolt:** Yamiry YR01 or YR05, which are shaped as handle locks. - **Front door with deadbolt bore:** Wyze Bolt v2 or eufy C220\. Heavier, Wi-Fi built in. - **Mixed household with a mix of doors:** pair one deadbolt for the entry with one or two knobs for bedrooms and the office. The mistake I see most often is buying a deadbolt for a bedroom that has no deadbolt bore, then paying a locksmith more than the lock to cut one. ## 1\. Evanshow Fingerprint Door Knob — Best overall **A 1.2 lb knob that swaps in without drilling and unlocks in half a second.** [![Evanshow biometric fingerprint door knob in matte black — the lightest published weight in this set at 1.2 lb](https://m.media-amazon.com/images/I/41uXwGuRsuL._SL500_.jpg)](https://www.amazon.com/dp/B0F375TD2P?tag=dieless-20) **Best for:** hollow interior doors and rentals where drilling is off-limits **Skip it if:** you need a Wi-Fi deadbolt for the front entrance The Evanshow is the lightest lock in this comparison by a clear margin, at 1.2 lb against a set average closer to 2 lb, and the small 1 x 2 x 1.97 in body barely changes the look of the door. It is a knob, so it replaces a standard knob without a new bore, and Evanshow says it fits doors 1.18 to 1.97 in thick, which covers most modern interior slabs. The 4-in-1 access setup gives you up to 100 fingerprints and 50 codes, plus a pair of mechanical keys and four IC cards for guests. Evanshow says fingerprint recognition takes under half a second. Two caveats. The listing carries no published warranty term, and there is no Wi-Fi or app, so remote unlocking is not on offer. It also has a first-run trap Evanshow spells out plainly: until you register an admin fingerprint, any fingerprint opens the door. Set the admin before you fit it. Against the rest of the set, this pick trades connectivity and a stated warranty for weight and price. On a hollow bedroom door, that is exactly the trade you want. **Pros:** - Lightest weight in the set at 1.2 lb - No drilling, fits 1.18-1.97 in thick doors - 100 fingerprints and 50 codes, plus IC cards and keys - Cheapest of the seven **Cons:** - No Wi-Fi and no app - No warranty term stated in the listing - Requires admin fingerprint setup before it is safe to use [Check Price on Amazon](https://www.amazon.com/dp/B0F375TD2P?tag=dieless-20) ## 2\. GHome Smart Fingerprint Door Lock — Runner-up **A 1.65 lb knob with app control and a rechargeable battery instead of AAs.** [![GHome fingerprint door knob in glossy silver with keypad and central fingerprint sensor](https://m.media-amazon.com/images/I/4161x9SiN0L._SL500_.jpg)](https://www.amazon.com/dp/B0DHS46L2F?tag=dieless-20) **Best for:** app-driven households that want a light knob with a rechargeable battery **Skip it if:** you want a lock under 1.5 lb The GHome sits in the sweet spot between the Evanshow's simplicity and the heavier deadbolts. At 1.65 lb it is still a light knob, but you get four unlock methods, a fingerprint capacity of 20 prints, and app management with no separate gateway. GHome claims 0.2 s recognition once a print is enrolled, which is quicker than most vendors quote here. The rechargeable 400 mAh battery is the interesting move. GHome quotes 10,000 unlocks or 300+ days per charge, with a 4-6 hour top-up over USB. That is a real advantage if you dislike keeping a drawer full of AAs, and it is the only pick in this set with a rechargeable pack instead of disposables. Against the field, the GHome loses on raw weight to the Evanshow and on capacity too, since 20 fingerprints is a fifth of what the winner offers. It gains an app and a rechargeable battery. On a slightly heavier hollow door, or in a household that manages access from a phone, it is the right call. **Pros:** - App control with no gateway needed - Rechargeable 400 mAh battery, no AAs - 0.2 s recognition claim from GHome - Second-cheapest of the seven **Cons:** - Only 20 fingerprints - No published warranty term - Heavier and bulkier than the Evanshow [Check Price on Amazon](https://www.amazon.com/dp/B0DHS46L2F?tag=dieless-20) ## 3\. KLLOQUE Fingerprint Door Lock — Best warranty **The only pick in this set with a written warranty and a light 1.63 lb body.** [![KLLOQUE matte black fingerprint smart door knob with integrated keypad and sensor](https://m.media-amazon.com/images/I/41kwKnzD3yL._SL500_.jpg)](https://www.amazon.com/dp/B0D1BR28N8?tag=dieless-20) **Best for:** buyers who want a written warranty on a low-cost knob **Skip it if:** you want Wi-Fi or app control The KLLOQUE is the only lock here with a stated warranty, at 1 year, which matters more than the listings make obvious. Every other pick in this set publishes nothing on that front, so if the sensor dies at month eight you are relying on Amazon's return window rather than a manufacturer promise. At 1.63 lb and 3.5 x 9 x 3.5 in, the body is compact enough for interior use, and KLLOQUE describes it as a 3-in-1 keyless entry knob for bedrooms with three access modes. The trade-off is that the feature list stops there. There is no app, no Wi-Fi, no rechargeable battery, and the listing is thinner on hard specifications than the top two picks. Fingerprint capacity is not published, which is a real gap when you are trying to compare like with like. Against the set, the KLLOQUE loses on features and gains on paper protection. If you want a light bedroom knob and you value knowing what happens when it breaks, this is the pick. **Pros:** - Only pick with a published warranty, 1 year - Light at 1.63 lb - Simple three-mode operation - Matte black finish suits modern hardware **Cons:** - No app or Wi-Fi - Fingerprint capacity not published - Thinner feature listing than most of the set [Check Price on Amazon](https://www.amazon.com/dp/B0D1BR28N8?tag=dieless-20) ## 4\. Yamiry Fingerprint Knob YR01 — Best minimal setup **A slim 0.79 x 5.5 x 2.95 in handle knob aimed at rental turnovers.** [![Yamiry YR01 matte black fingerprint door handle with integrated keypad](https://m.media-amazon.com/images/I/41KO4rboWdL._SL500_.jpg)](https://www.amazon.com/dp/B0C66NCTXX?tag=dieless-20) **Best for:** landlords adding keyless entry to a rental without a rewire **Skip it if:** you need a published weight before you buy Yamiry pitches the YR01 at landlords and property managers, and the feature list backs that up: a 6-in-1 unlock claim, app-based access management, and installation Yamiry describes as quick and screwdriver-only. The slim 0.79 in depth is the tell, so the lock does not stick out from the door face the way a deadbolt does, which is useful for tenant photos and short-term rentals where the door needs to look normal. The gap you have to accept is that the listing publishes no weight. Given the small footprint and knob-style form factor, it is likely light, but "likely" is not the same as printed on the spec sheet. If your door is genuinely hollow and thin, ask Yamiry before you buy. Against the set, this pick's real strength is the management story rather than the hardware. If you swap fingerprints and codes every few months as tenants move in and out, the app matters more than half a pound of weight. For a fixed home household, the Evanshow does more for less. **Pros:** - App-based access management for turnovers - Slim 0.79 in depth - 6-in-1 unlock claim including fingerprint, code and app - Screwdriver install per Yamiry **Cons:** - Weight not published - Fingerprint capacity not listed - No published warranty term [Check Price on Amazon](https://www.amazon.com/dp/B0C66NCTXX?tag=dieless-20) ## 5\. Wyze Auto-Lock Bolt v2 — Best upgrade **A 3.25 lb Wi-Fi deadbolt with USB-C emergency power and 8-month battery life.** [![Wyze Auto-Lock Bolt v2 black deadbolt with anti-peep keypad and fingerprint sensor](https://m.media-amazon.com/images/I/41HLSGMV-1L._SL500_.jpg)](https://www.amazon.com/dp/B0FD3WMV2T?tag=dieless-20) **Best for:** front-door use where you want Wi-Fi, auto-lock and USB-C backup **Skip it if:** your door is hollow or you want a light knob Step up to the Wyze and you leave the light-knob category. At 3.25 lb and 1.41 x 7.09 x 2.93 in, this is a deadbolt for a solid exterior door with a proper deadbolt bore, and the trade you make for that weight is real capability. Wyze quotes 0.5 s fingerprint recognition, 8 months of use on 8 AA batteries, and a USB-C port so you can hit it with a common power bank when the batteries run flat. That last detail solves the classic smart-lock lockout problem cleanly. Wyze says the AI scanner learns your fingerprint over time, which they claim improves recognition on repeat use. Built-in Wi-Fi means no bridge, and pairing with a Wyze Video Doorbell lets you unlock from the live feed. The listing also cites a BHMA2 grade and an IP53 rating for weather ingress, and includes physical backup keys. Against the set, the Wyze is the heaviest lock here and the most expensive. Put it on a hollow bedroom door and the wrong things happen. Put it on a front door and it earns its keep. **Pros:** - Wi-Fi built in, no bridge - USB-C emergency power backup - 8-month battery life on 8 AAs per Wyze - BHMA2 and IP53 claims from the listing - Auto-lock and anti-peep keypad **Cons:** - Heaviest lock in the set at 3.25 lb - Most expensive pick - Deadbolt form factor, not a drop-in knob replacement [Check Price on Amazon](https://www.amazon.com/dp/B0FD3WMV2T?tag=dieless-20) ## 6\. Yamiry Handle Lock YR05 — Best for pros **A 2.6 lb aluminium handle lock with key fob support and optional Wi-Fi.** [![Yamiry YR05 matte black fingerprint keyless entry handle lock with fingerprint sensor and keypad](https://m.media-amazon.com/images/I/41z-IT9IUHL._SL500_.jpg)](https://www.amazon.com/dp/B0DGQ8HCVB?tag=dieless-20) **Best for:** installers who want key fobs plus optional Wi-Fi gateway control **Skip it if:** you want Wi-Fi in the box without buying a bridge The YR05 is Yamiry's heavier, more configurable sibling to the YR01, at 2.6 lb and 3 x 5.62 x 2.69 in, with an aluminium build the brand highlights for corrosion resistance and tamper resistance. It runs a 5-in-1 unlock stack: app, code, key fob, fingerprint and physical key, with a claimed capacity of 50 codes and fingerprints. Locking has three modes, including auto-lock and a long-press button. The Wi-Fi story is the catch. The YR05 pairs over Bluetooth in the box and needs a separate gateway, sold separately by Yamiry, before you can control it remotely. That is a fair setup for pros who spec locks across multiple doors and want a single gateway serving them, but it is a downgrade from the Wyze and eufy, which have Wi-Fi baked in. Against the set, this pick's advantages are the key fob support, which no other lock here offers, and the compatibility with most American standard doors that Yamiry claims. The downside is the price tier without built-in Wi-Fi. **Pros:** - Key fob support, unique in this set - Aluminium body per Yamiry - 50 codes and fingerprints - Compatible with most American standard doors per the listing - Three locking modes including auto-lock **Cons:** - Wi-Fi needs a separately sold gateway - Second-heaviest at 2.6 lb - Premium price without built-in Wi-Fi [Check Price on Amazon](https://www.amazon.com/dp/B0DGQ8HCVB?tag=dieless-20) ## 7\. eufy Security Smart Lock C220 — Best premium **A Wi-Fi deadbolt with HomeKit, app and self-learning fingerprint AI.** [![eufy Security C220 fingerprint keyless entry deadbolt in black with keypad](https://m.media-amazon.com/images/I/31gYCXL3t9L._SL500_.jpg)](https://www.amazon.com/dp/B0C7C69FPS?tag=dieless-20) **Best for:** eufy households wanting a deadbolt tied to a doorbell camera **Skip it if:** you already own a knob-only door with no deadbolt cutout The eufy C220 is the connected-home pick. eufy claims six ways to unlock, including fingerprint under 1 s, app, keypad, physical key and Apple support, and the built-in Wi-Fi means no bridge and no gateway purchase to worry about. eufy also quotes about 8 months on 8 AA batteries, matching the Wyze on that front, and pitches a self-learning AI that tightens recognition on repeat prints. Dimensions land at 4.41 x 7.67 x 4.49 in, so it is bulkier than any knob here. Where this pick pulls ahead of the Wyze is the ecosystem integration. If you already own a eufy doorbell, the C220 folds into eufy Security app routines, so you can trigger unlocks alongside camera events. If you do not own any eufy hardware, the reason to pick it over the Wyze narrows. Against the set, the C220 is the most expensive lock, has no published weight or warranty on this listing, and is the oldest design here with a 2017 release. Two sellers list it, which is the widest availability in this comparison. **Pros:** - Built-in Wi-Fi, no bridge - HomeKit-compatible per eufy - 8-month battery life claim - Fits into eufy doorbell routines - Two sellers list it, the widest here **Cons:** - Most expensive pick - Weight not published - 2017-released design, oldest here - No published warranty term [Check Price on Amazon](https://www.amazon.com/dp/B0C7C69FPS?tag=dieless-20) ## What the listings never tell you about lightweight locks Three things repeatedly go missing from fingerprint lock listings, and each one bites after you install. 1. **Latch backset.** Most bedroom doors use a 2-3/8 in backset, but exterior doors often use 2-3/4 in. None of these listings publish the backset clearly, and the wrong one means the latch does not reach. 2. **Handedness.** A knob has to swing the way the door swings. The Evanshow listing at least says left or right, which is more than most. 3. **Sensor lifespan.** Fingerprint sensors wear with use. None of the listings publish a rated cycle count, and only the KLLOQUE publishes a warranty term to fall back on. Ask the seller these three questions before you buy if the answers are not in the listing. A short pre-purchase message is cheaper than a return. ## How many unlock methods do you actually use? Every lock here brags about a number: 4-in-1, 5-in-1, 6-in-1\. Most households use two, occasionally three. Here is the honest breakdown: - **Fingerprint** for the household. Used daily. - **Code** for visitors and cleaners. Used weekly at most. - **Physical key** for the day the batteries die. Used once. - **App** for granting access remotely. Used monthly if at all, and only if you have Wi-Fi in the lock. - **Key fob or IC card** for kids or elderly relatives whose prints do not read well. Situational, and only the Yamiry YR05 and the Evanshow offer this. If your household is small and the door is a bedroom, three methods is plenty and the Evanshow covers it. If you are managing a rental or want to unlock from the office, you need the app tier, which is where the GHome, Yamiry YR01 and Wyze earn their keep. ## The verdict For a lightweight fingerprint smart lock on an interior or bedroom door, the Evanshow Biometric Door Knob is the right default. It is the lightest lock in this set at 1.2 lb, the cheapest, and the only knob here that publishes both a door thickness range of 1.18-1.97 in and a fingerprint capacity as high as 100\. On a hollow door, that combination is the difference between a lock that sits flush for years and a lock that sags in months. The runner-up is the GHome Smart, and it wins in exactly one case: when you want app control and a rechargeable battery on a light knob and can accept 20 fingerprints. That is a real household profile, especially for families that swap access often. Step outside the lightweight brief and the Wyze Auto-Lock Bolt v2 is the front-door pick, because a 3.25 lb Wi-Fi deadbolt with a USB-C emergency port belongs on a solid exterior slab, not a bedroom. The eufy C220 wins only inside an existing eufy setup, and the Yamiry YR05 wins only if you specifically need key fob support. ## FAQ ### What makes a fingerprint smart lock lightweight? What makes a fingerprint smart lock lightweight is the total assembled weight against the door type it sits on. Under 1.7 lb is safe for most hollow interior doors, which is where the Evanshow at 1.2 lb, KLLOQUE at 1.63 lb and GHome at 1.65 lb land. Above 2.5 lb, you are into deadbolt territory and need a solid-core door. ### Is a lightweight fingerprint smart lock worth it over a code-only lock? A lightweight fingerprint smart lock is worth it when you unlock the door more than a few times a day. Fingerprint entry is faster than punching a code, roughly half a second on the Evanshow and Wyze claims, and it removes the shared-code hygiene problem in rentals. If the door opens twice a day, a code-only lock saves you money and battery worry. ### How thick a door does the Evanshow fit? The Evanshow fits doors from 1.18 to 1.97 in thick, per the listing, and covers left and right swings. That range picks up most modern interior slabs and slim exterior doors, but it excludes many older solid-timber exterior doors that run over 2 in. Measure your door edge before you buy, because return shipping on a hardware item eats any saving. ### Evanshow or GHome, which should I pick? Between Evanshow and GHome, pick Evanshow for the lightest weight, the biggest fingerprint capacity at 100 prints, and the lowest price. Pick GHome if you want an app on your phone, a rechargeable 400 mAh battery instead of AAs, and can accept 1.65 lb and only 20 fingerprints. The Evanshow wins for pure bedroom use; the GHome wins for managed access. ### What is the biggest mistake buyers make in this category? The biggest mistake buyers make is fitting a heavy deadbolt on a hollow interior door. A 3 lb lock hung on a cardboard-core bedroom door drags the latch out of true within weeks, and the fingerprint sensor gets blamed for something that is really a mechanical alignment problem. Match the lock weight to the door core, then worry about features. A last practical note. Before you fit any of these, take a photo of the existing hardware from the front and the edge, and measure the door thickness with a ruler across the latch cutout. Those two data points solve most fit problems before they start. Once the lock is in, register the admin fingerprint immediately, because the Evanshow in particular treats any print as valid until you do, and that is a security gap you introduced yourself. Start with a light knob on the interior doors that see the most traffic, live with it for a month, and only then decide whether the front door deserves the Wyze upgrade. *Last updated: September 7, 2026\.
