eufy Smart Lever Lock C33: Smart Fingerprint Lever Lock for Fast, Keyless Entry

The eufy Smart Lever Lock C33 is a Wi-Fi-enabled smart lever lock designed to simplify access control for homes, side doors, garages, offices, and basement entrances. It combines fingerprint recognition, app control, keypad entry, NFC card access, and a physical key backup into one compact security solution, making it a practical choice for users who want convenience without sacrificing everyday reliability.

One of its biggest advantages is the built-in fingerprint sensor integrated into the lever handle, which allows fast, natural unlocking as you grasp the door. The lock also supports remote access through the eufy app, real-time notifications, access history, and passcode management, which is useful for families, landlords, small offices, and short-term rental hosts. Installation is another strong point: eufy says it can be installed in about 15 minutes without drilling, and it works with both left- and right-hand doors.

The product is especially appealing for households that want shared access for multiple users, including children and older adults, and for anyone looking for a modern replacement for traditional keyed hardware. At launch, the eufy Smart Lever Lock C33 has been listed at about $169.99 in the US and around $349.95 in Australia, so availability and pricing vary by region. It is typically sold through eufy’s online store and major retail channels when in stock.

Compared with a standard smart deadbolt, the eufy Smart Lever Lock C33 is better suited to lever-style doors where a handle is more convenient than a deadbolt-only setup. Relative to other smart lever locks, it stands out for its built-in fingerprint access and broad local storage for users and passcodes.

Troubleshooting the eufy Smart Lever Lock C33

Lock will not connect to the app: confirm you are using a 2.4 GHz Wi-Fi network, not 5 GHz, and move the phone closer during setup.
Fingerprint unlock fails: clean the sensor, re-register the fingerprint, and ensure the finger is placed consistently across the sensor and handle grip.
Battery warning appears: replace all 8 AA batteries at the same time when the app shows low battery below 20%.
Lock is unresponsive: use the USB-C port for emergency power, or use the physical key if the batteries are fully depleted.
Door alignment issues: check that the lock body and strike plate are correctly aligned and that your door meets the required bore and thickness dimensions.
Access control problems: verify that passcodes, fingerprints, and NFC cards were added correctly in the eufy app.

Preventive maintenance is simple: keep batteries fresh, avoid exposing the lock to heavy rain, and test the lever and latch periodically for smooth operation. The lock is backed by 24/7 support and 18-month coverage, and customers can contact eufy through phone, email, or live chat for help with setup, pairing, or warranty support.
