Eufy Fingerprint Door Lock Review

The Eufy Smart Lock Touch & Wi-Fi (T8520) is a top-tier choice for those wanting a reliable keyless lock. It uses a capacitive fingerprint sensor that reads prints in under a second, based on published specifications. The built-in Wi-Fi allows you to lock or unlock the door remotely via the Eufy Security app, and it also supports voice control through Alexa and Google Assistant.

Owner reviews highlight its sturdy metal construction and simple installation process, which fits standard US deadbolt preparations. The IP65 weather rating means it can handle rain and dust, making it suitable for exterior doors. Some users note the app occasionally has a slight delay in loading the live status, but overall, it is praised for its performance and security features.

The Eufy Smart Lock Touch (T8510) is a more affordable option that still delivers excellent fingerprint recognition. It uses the same capacitive sensor as the T8520 but relies on Bluetooth for connectivity, which means you need to be within range to control it via the app. For many users, this is not an issue, as the primary entry method is the fingerprint reader.

Owner reviews report that the lock is easy to install and works reliably over time. The battery life is rated at up to 12 months, and the IP65 rating ensures it can withstand outdoor elements. The main drawback is the lack of built-in Wi-Fi, which limits remote access unless you purchase a separate Eufy Wi-Fi bridge. This makes it a great choice for those who primarily use the fingerprint sensor and do not need remote features.

This variant of the T8520 adds a physical keypad, giving users more entry options. It is ideal for households where guests or family members may not want to use fingerprints. The keypad is backlit for easy use at night and supports up to 50 unique codes, which can be scheduled for temporary access.

Owner reviews appreciate the flexibility of having both fingerprint and keypad access. The lock retains the same fast Wi-Fi connectivity and strong build quality as the standard T8520. Some users report that the keypad buttons can be less responsive in very cold temperatures, but this is a common issue with capacitive touch keypads. Overall, it is a versatile choice for busy households.

The Eufy Smart Lock (T8500) is the entry-level model, offering basic fingerprint access without smart features. It uses an optical fingerprint sensor, which is slightly slower than the capacitive sensor found in higher-end models. It is designed for users who simply want a keyless lock without needing an app or remote control.

Owner reviews note that it is straightforward to install and use, with reliable fingerprint recognition for most users. The battery life is rated at up to 10 months, and the IP65 rating makes it suitable for outdoor use. The main limitation is the lack of connectivity, meaning you cannot check lock status or grant access remotely. It is best for those on a tight budget or for secondary doors.

This version of the T8520 is specifically designed as a deadbolt lock, offering enhanced physical security. It includes a tamper alarm that sounds if someone tries to force the lock, and an auto-lock feature that secures the door after a set time. The capacitive fingerprint sensor is fast and accurate, and the Wi-Fi connectivity allows for remote monitoring.

Owner reviews highlight the robust construction and peace of mind from the security features. The lock is slightly larger than standard models, so it may not fit all door preparations without modifications. The installation process requires careful alignment to ensure the deadbolt operates smoothly. It is a top choice for those prioritizing security over aesthetics.
