Evanshow Fingerprint Door Lock is the top pick for most buyers and the best budget door lock for one clear reason: it offers keyless fingerprint access without requiring you to carry or share a key. That makes daily entry faster and reduces the hassle of spare keys for family members or guests.
This guide is for homeowners, renters with compatible doors, and anyone replacing an older deadbolt. The most important factors are door compatibility, lock size, construction materials, and battery life. A fingerprint reader can be convenient, but it matters less if the unit cannot fit your door or needs frequent battery changes. The six picks below are ranked with clear reasons for each choice, along with honest drawbacks that may affect your decision.

6 Budget Door Locks Worth Considering
This ranked list counts down from the most affordable option to the top pick, with key features and trade-offs made clear.
6. Copper Creek Entry Door Knob
Best for: Renters upgrading interior entry doors
The Copper Creek Entry Door Knob is a keyed lockset for bedrooms, bathrooms, closets, offices, and other doors that need basic access control. A key opens it from the outside, while a turn button locks and unlocks it from inside. The included latch adjusts between 2-3/8-inch and 2-3/4-inch backsets, and the hardware fits doors measuring 1-3/8 to 1-3/4 inches thick.
Its satin stainless finish gives the knob a simple silver appearance that works with many interior styles. The all-metal construction should feel more substantial than plastic-heavy budget knobs, while ANSI Grade 3 certification suits typical residential use. Installation requires only a screwdriver and should take about five minutes for a compatible door. At around $12, it is an inexpensive way to replace a worn knob or add keyed access to an interior room. The main limitation is security level. Grade 3 is the basic residential ANSI rating, so this is not a substitute for a heavy-duty entry handle or deadbolt on an exterior door.
Pros
- Adjustable latch supports both 2-3/8-inch and 2-3/4-inch backsets.
- Keyed outside access and an interior turn button suit private rooms.
- All-metal construction and a satin stainless finish provide a sturdier, neutral-looking replacement.
Cons
- ANSI Grade 3 protection is basic and may not suit high-security exterior entrances.
- A keyed knob alone offers less resistance than a knob paired with a deadbolt.
5. iulock Keypad & Key Smart Door Lock
Best for: Rental homes and shared entry doors
The iulock Keypad & Key Smart Door Lock replaces a standard knob with a matte-black electronic entry system. It supports up to 50 user codes, with each code using 1 to 15 digits. That setup suits families, cleaners, renters, or office staff who need separate access. The metal construction, two backup keys, and removable silicone grip add practical touches without making the design bulky. At around $36, it costs less than many connected smart locks.
Its keypad has backlit numbers for nighttime use, plus passage mode when you want the door to stay unlocked. Silent mode can reduce keypad sounds. Four AAA batteries are rated for up to 18 months, and a low-battery alert provides warning before replacement. If the batteries die, a USB-C backup port can provide emergency power. The lock fits doors from 1⅜ to 2½ inches thick and includes an adjustable 2⅜- or 2¾-inch latch. IP65 weather resistance and an operating range from -22°F to 176°F support exterior use, but installation still depends on the existing door and latch fit.
Pros
- Stores up to 50 customizable access codes.
- Includes auto-lock, passage, silent, and low-battery modes.
- Fits a broad range of door thicknesses with a reversible design.
Cons
- It uses four AAA batteries, not a rechargeable battery pack.
- IP65 protection resists rain and dust, but it is not designed for water submersion.
4. Fingerprint Smart Door Lock with Keypad
Best for: Bedroom and home-office privacy
This electronic door handle replaces a traditional knob with five access options: fingerprint, password, IC card, app control, and a mechanical key. It stores up to 100 fingerprints and 50 passwords, giving households or rental hosts room for multiple users. The manufacturer lists fingerprint recognition at 0.2 seconds, with unlocking in about one second. Around $50, it offers more entry choices than a basic keypad lock.
The handle fits standard US doors with 2-3/8-inch or 2-3/4-inch backsets, 2-1/8-inch side holes, and door thicknesses from 1-3/8 to 2-1/8 inches. Its flip-up design works on left- or right-opening doors. Four AAA batteries power the lock, but they are not included. A low-battery alert and USB-C emergency port help prevent lockouts. The package also includes two keys and two IC cards. A 30-day money-back period and 12-month warranty add some purchase protection.
Pros
- Five entry methods cover family members, guests, and rental users.
- Stores up to 100 fingerprints and 50 passwords.
- USB-C emergency power can restore access after battery failure.
Cons
- Four AAA batteries are required and must be purchased separately.
- App features may depend on phone compatibility and setup, which is not specified.
3. Fingerprint Smart Door Knob Lock
Best for: Interior bedroom and apartment doors
This matte-black smart door knob combines fingerprint entry, Bluetooth app control, and mechanical keys. It suits bedroom doors, apartments, and Airbnb properties where users want more privacy than a standard knob. The app can add fingerprints, review access records, and share entry access with family members. At around $32, it offers several unlocking methods without reaching smart-lock prices.
App control works only within Bluetooth range. Remote operation requires a separately purchased gateway. The built-in rechargeable battery is rated for up to one year and charges through USB Type-C. Users can enable low-battery alerts, which appear when the battery falls below 20% during app unlocking. Installation requires a screwdriver, but the setup has a few precise steps. Both knobs must follow the “UP” marks, the spindle must sit vertically, and the thumb-turn arrow must align with the center dot. A mechanical key provides a backup if the battery runs out or the app is unavailable.
Pros
- Fingerprint, app, and key entry give you three access options.
- Rechargeable battery reduces the need for disposable batteries.
- Access records and shared permissions help manage family or guest entry.
Cons
- Bluetooth control does not work remotely without buying a separate gateway.
- Installation depends on careful knob, spindle, and thumb-turn alignment.
2. Ulecoce Fingerprint Keypad Deadbolt Knob Set
Best for: busy households needing flexible access
The Ulecoce Fingerprint Keypad Deadbolt with Knob Set replaces a standard deadbolt with keyless entry. Its matte black finish suits many front doors, and the design supports left- or right-hand opening. Access options include fingerprint scanning, keypad codes, the companion app, one-touch unlocking, and five physical backup keys. The lock costs around $53, though prices change.
The fingerprint reader is rated to recognize a print in 0.3 seconds and unlock within one second. It can store up to 512 fingerprints and keypad passcodes, while the app can create one-time, scheduled, recurring, or permanent codes. Auto-lock timing adjusts from 5 to 60 seconds. App features include access logs, battery checks, temporary codes, and remote unlocking within 5 meters. Alexa and Google Assistant support requires a separate Ulecoce gateway. Installation uses a screwdriver and fits standard doors. The brand lists a three-year warranty and lifetime support.
Pros
- Five entry methods reduce reliance on one access option.
- Adjustable auto-lock helps secure the door after closing.
- Temporary and scheduled codes suit guests, cleaners, and deliveries.
Cons
- Remote access and voice control require the separately sold gateway.
- Fingerprint and app functions depend on batteries and electronics, so the five keys remain essential backups.
1. Evanshow Fingerprint Door Lock
Best for: Bedrooms, offices, and rental apartments
The Evanshow biometric door knob combines fingerprint access, a keypad, two mechanical keys, and four IC cards. It supports up to 100 fingerprints and 50 passwords, giving families, guests, or coworkers several ways to enter. The black lock fits wooden doors from 1.18 to 1.97 inches thick and works with either left- or right-swing doors. At around $30, it offers more access methods than a basic keyed knob.
Its fingerprint scanner is designed to recognize a registered print in about 0.5 seconds. That quick entry can be useful when your hands are full, though actual results may vary by finger condition and setup. Installation requires no drilling or wiring, and the included tools and video guide should help most buyers replace a compatible knob. Before anyone uses it, register an administrator fingerprint. Until then, any fingerprint can unlock the door. A USB port accepts emergency power from a power bank, but it does not recharge the lock’s internal batteries.
Pros
- Four entry methods cover fingerprints, passwords, IC cards, and keys.
- Stores up to 100 fingerprints and 50 passwords for shared access.
- Fits 1.18- to 1.97-inch wooden doors without new wiring or drilling.
Cons
- Initial setup has a serious security risk if an administrator print is not registered first.
- The emergency USB port powers the lock temporarily but cannot recharge its batteries.
Buying Guide
Security certification matters most when choosing an affordable door lock. Look for an ANSI/BHMA Grade 1 or Grade 2 deadbolt, since these ratings indicate stronger resistance to forced entry than an unrated model.
- Security grade: Choose ANSI/BHMA Grade 2 for most homes, or Grade 1 for exterior doors that face higher risk. Avoid locks with no published grade.
- Door fit: Confirm the lock supports your door thickness, usually 1⅜ to 1¾ inches. Measure the backset, which is commonly 2⅜ or 2¾ inches.
- Strike plate: Pick a model with a metal strike plate and screws at least 2½ to 3 inches long. Short screws can leave the frame vulnerable.
- Key control: Prefer a lock with two or more included keys and a replaceable cylinder. Rekeyable models cost more upfront but simplify future key changes.
- Price and installation: Basic keyed deadbolts usually cost $15 to $40. A budget smart lock often costs $60 to $120 and may need four AA batteries, Wi-Fi, or a separate hub.
If you cannot get everything, prioritize the certified security grade and a proper fit for your door.
Frequently Asked Questions
How do I choose a reliable low-cost door lock?
Choose a lock with the right door fit, a solid metal latch, and a keyed or keypad system that matches your security needs. For example, an exterior deadbolt should usually have a 1-inch throw and fit doors about 1-3/8 to 1-3/4 inches thick.
What features matter most in an affordable door lock?
The key features are a strong deadbolt, a durable metal strike plate, privacy protection, and a lock body that fits your door. An ANSI/BHMA Grade 2 deadbolt is a practical target for many homes, while a reinforced strike plate with 3-inch screws can improve resistance to forced entry.
Can a cheap smart lock be secure?
Yes, a low-priced smart lock can be secure if it uses strong encryption, automatic updates, and a protected deadbolt, but its security depends on setup and software support. A model with two-factor authentication and at least 128-bit encryption is preferable for remote access.
Are keypad locks worth buying for a tight budget?
Yes, keypad locks can be worth buying on a tight budget when you want keyless entry and can accept battery checks and occasional code changes. Many basic models use four AA batteries and let you create several user codes for family or guests.
Conclusion
Evanshow Fingerprint Door Lock remains the top recommendation for buyers who want key-free entry, quick access, and a lower-cost alternative to more expensive smart locks, without adding a separate key to daily routines. If your priority is the simplest installation, lowest purchase price, or dependable access during a dead battery, choose a conventional keyed lock instead, because its operation is easier to understand and maintain. Before placing an order, measure your door and existing bore holes, confirm the lock fits your door thickness and latch setup, check how many locks the package includes, and compare the current price across sellers, since discounts, bundles, and included parts can change the value.
