eufy, the smart home brand from Anker, has built its reputation on security devices that work without a monthly fee and install in minutes. Its keyless entry door locks replace the thumb-turn side of an existing deadbolt, and most have built-in Wi-Fi, which means you can lock and unlock from your phone anywhere without buying a separate hub. For a first-time buyer, the hardest part is sorting out the terms: fingerprint, palm vein, video lock, Matter and BHMA grade.
The six models below differ mainly in how you get in: keypad-only models (C30 and C210), a fingerprint lock (C220), video locks with a built-in camera (E330 and S330) and a palm vein lock (FamiLock E34).

The listing names six ways in: fingerprint, the eufy Security app, the keypad, a physical key, Apple Watch and voice through Alexa or Google Assistant.
It runs on 8 AA batteries for around 8 months, depending on use. Built-in Wi-Fi means no bridge, which is a small plug-in box some locks need to reach your router. It fits most standard deadbolts, handles bores under 54mm by removing a spacer and installs in about 15 minutes without drilling. It carries BHMA Grade 3 certification after more than 100,000 lock and unlock cycles, an IP53 rating for splashes and rain, an operating range of -22°F to 158°F and an alarm for unusual unlock attempts. Two keys and the batteries are included.

eufy Security Smart Lock C30 for a Simple First Smart Lock
The eufy Security Smart Lock C30 is a straightforward keypad lock with built-in Wi-Fi and no hub required. You can unlock it with the keypad, the app, Alexa or Google Assistant, or the physical key, and the listing does not mention a fingerprint reader.
It runs on 4 AA batteries for up to 5 months and has a low battery indicator. Its standout feature for busy households is auto-lock with a customizable countdown timer, so the door locks itself a set time after you close it. Like the C220, it has an IP53 exterior, a -22°F to 158°F operating range, BHMA Grade 3 certification and a 15-minute install without drilling. eufy notes durable physical buttons and 18-month protection, with no monthly fee.
The C30 suits renters and first-time buyers who want remote access and auto-lock but do not need fingerprints. If you already use an Apple Watch, the C210 lists watch unlocking.
eufy Security Smart Lock C210 for Keypad and Apple Watch Users
The eufy Security Smart Lock C210 is another keypad model, previously sold as the E110, and the listing says there is no difference between the two names. It offers five ways to unlock: the app, the touchscreen keypad, a physical key, Apple Watch and voice through Alexa or Google Assistant.
Built-in Wi-Fi gives you access management, real-time notifications and an event history in the eufy Security app, which is handy for seeing when a child gets home from school. It fits most standard US deadbolts, installs in about 15 minutes without drilling, includes 4 AA batteries and is BHMA certified after more than 100,000 cycles, though the listing does not state the grade.

eufy Security Video Smart Lock E330
Best for: Seeing visitors and unlocking by fingerprint
Pros
- 2K HD camera with f/1.6 lens
- 10,000mAh rechargeable battery
- IP65 weather resistance
- Works with eufy Chime and HomeBase 3
Cons
- Thumbnails stored briefly in cloud
- Battery needs recharging
The eufy Security Video Smart Lock E330 combines a fingerprint lock with a 2K HD camera and an f/1.6 lens, which lets in more light for clearer video after dark. You can see visitors and manage access in the eufy Security app, with real-time notifications. The listing notes that thumbnail preview images in notifications are stored temporarily in the cloud.
Unlocking options include fingerprint, the app, Alexa or Google Assistant, the keypad and physical keys. Power comes from a 10,000mAh rechargeable battery rather than AAs, which means you will charge it instead of swapping batteries. It installs in about 15 minutes on most standard US deadbolts, carries BHMA Grade 3 certification and has an IP65 rating, which is better protection against rain and dust than the IP53 models. It also works with eufy Chime, Chime 2, HomeBase 3 and compatible eufy cameras and doorbells, sold separately.
The E330 suits anyone who wants front-door video without a separate doorbell camera. If you also want a doorbell button and chime in the box, the S330 fits better. For more on how eufy’s locks compare as a family, see our wider guide to the eufy smart door lock range.
eufy Security Video Smart Lock S330 for an All-in-One Front Door
The eufy Security Video Smart Lock S330 is described as 3-in-1: fingerprint recognition, a 2K HD camera and a video doorbell in one device, with a chime included. The listing mentions five unlocking methods, including fingerprint, the eufy Security app and voice assistants, and it lists a Wi-Fi deadbolt and a 10,000mAh rechargeable battery.
Beyond that, the listing is brief. It does not specify installation time, BHMA grade, weather rating or which deadbolts it fits, so check the product details closely before buying for an unusual door.
The S330 suits someone replacing both an old doorbell and a deadbolt at once. If you do not need the doorbell piece, the E330 gives you a better-documented video lock.
eufy Security Smart Lock FamiLock E34 for Palm Vein Unlocking
The eufy Security Smart Lock FamiLock E34 uses palm vein recognition. Instead of reading a fingerprint on the skin, it scans the vein pattern inside your palm, which eufy calls forgery-proof, with 99.9% accuracy and recognition in 0.6 seconds. The data stays stored locally on the lock rather than in the cloud.
It uses a 10,000mAh rechargeable battery for up to 8 months, plus a 750mAh non-removable backup battery that keeps it running while the main battery charges. It has built-in Wi-Fi and supports Matter, a shared smart home standard, so it can work with Apple Home, Google Home, Alexa and SmartThings. It fits standard US and Canada doors without drilling and comes with 18 months of electronic and 36 months of mechanical coverage. The listing does not mention a keypad, physical key or weather rating.
This suits Apple Home users and households where fingerprints read poorly, such as people with dry or worn fingertips. If you want video, pick the E330 instead.
How to Choose the Right eufy Keyless Entry Door Lock
Pick your unlock method. A keypad (C30, C210) is the simplest. Fingerprint (C220, E330, S330) is fastest for family members. Palm vein (E34) scans under the skin and is useful if fingerprints are unreliable.
Decide on video. The E330 and S330 have a 2K camera. If you already own a eufy doorbell, a non-camera lock paired with it in the app may be enough.
Think about power. AA models (C220, C30, C210) use swap-in batteries. The E330, S330 and E34 use a rechargeable 10,000mAh pack. The E34 adds a backup battery.
Check your door. Most of these fit standard deadbolts without drilling. If your door uses a knob lock rather than a deadbolt, our guide to the eufy door knob smart lock may suit you better.
