eufy Security Smart Lock FamiLock C32 4-Pack, Fingerprint Keyless Door Lock with Handle
Quick take
The eufy Security FamiLock C32 4-pack brings fingerprint keyless entry to multiple interior doors, with Wi‑Fi app control, auto-lock countdown, and support for multiple users. It stores up to 50 fingerprints and 100 passcodes, and it includes a low-battery alert plus emergency unlock options. The biggest thing to check before buying is door compatibility (cutout dimensions) and that rekeying is not supported.
Pros and cons
Pros
- Fast fingerprint unlocking, with a large-area array and 360-degree recognition.
- Designed for multi-user households, supporting up to 50 fingerprints and 100 passcodes.
- Wi‑Fi app control with real-time notifications, plus auto-lock with a countdown feature.
- Backup unlocking options include passcode and physical keys, with emergency power via USB-C.
Cons
- Rekey not supported, so changing keys later may be more limited than some lock styles.
- Not compatible with Apple HomeKit, IFTTT, or Matter.
- USB-C port is for emergency power supply only, not for charging the batteries.
- Installation depends on the required bore hole diameter, backset, and door thickness dimensions.
What buyers think
Buyer-review evidence is limited to a small set of detailed snippets, so it is not possible to identify strong, statistically reliable patterns. Still, the recurring themes are clear: setup and installation are generally described as quick and straightforward (including swapping an existing knob/lock), fingerprint unlocking is viewed positively for speed and daily usability, and the locks integrate well with the eufy ecosystem for users who already manage other eufy devices. Some feedback also notes that access assignment may require resetting the lock in at least one case, which suggests setup steps can be sensitive to how and when you add users.
Key features that matter for everyday use
Fingerprint entry built around speed and multi-user access
This smart lock focuses on fingerprint keyless entry, using a large-area fingerprint array for quick unlocking (rated at about 0.3 seconds) and 360-degree recognition to reduce “angle” friction. The self-learning AI algorithm is intended to optimize recognition over time for multiple users.
For household management, it supports up to 50 fingerprints and 100 passcodes. That makes it practical for families, shared spaces, and situations where you want controlled access without handing out traditional keys.
Control from the app, plus auto-lock convenience
With built-in Wi‑Fi, you can manage the lock through the eufy app and receive notifications. Auto-lock with countdown helps ensure the door locks after closing, reducing the chance of forgetting to secure it.
Unlock even when the battery is low
It includes a low-battery notification when the battery falls under 20%. If power fails completely, you have emergency unlock paths: a portable charger for emergency power via the USB-C port, or physical key access.
Important practical note: the USB-C port is for emergency power supply only, not for charging the lock’s batteries.
Voice control and smart home compatibility
The lock supports Alexa and Google Assistant. If you rely on Apple HomeKit, IFTTT, or Matter workflows, you will need a different platform or alternative smart lock, since this model is not compatible with those services.
Lock fit and compatibility checklist before you buy
Smart locks live or die by fit. Before purchasing the C32 4-pack, confirm your door meets the listed requirements. You will typically need:
- Bore hole diameter: 2 1/8 in
- Bore hole backset: 2 3/8 in or 2 3/4 in
- Door thickness: 1 3/8 in to 2 1/6 in
Material compatibility is described as suitable for doors with wood or metal construction.
Pros and cons, with buyer-fit clarity
Best for
- Interior doors where you want fingerprint access and quick day-to-day unlocking.
- Households that need multiple access methods, including passcodes and physical keys.
- People already using the eufy app ecosystem and want app control plus notifications.
Who should avoid it
- Buyers who need Apple HomeKit, IFTTT, or Matter integration.
- Anyone whose doors cannot meet the specific cutout and thickness requirements.
- Shoppers who strongly prefer a lock design that can be rekeyed later (rekey is not supported).
- Users expecting to charge the batteries via USB-C (USB-C is emergency power only).

Verdict
The eufy Security FamiLock C32 4-pack is a strong pick for interior-door convenience, especially if fingerprint access and multi-user management are your priority. It also covers the practical bases with Wi‑Fi app control, auto-lock countdown, and backup unlock options for power failures. Just make sure your doors match the required dimensions, and confirm your smart home compatibility needs align, since Apple HomeKit, IFTTT, and Matter are not supported and rekeying is not available.
