Best Eufy Keyless Door Lock of 2026

The Eufy T8520 is the flagship model that combines a capacitive fingerprint sensor with a backlit keypad and built-in Wi-Fi. Owner reviews on Amazon and Best Buy consistently rate the fingerprint reader as instant and reliable, even for dry or slightly wet fingers. The lock uses four AA batteries which Eufy claims last 6-8 months, and the low battery warnings are clear.

Installation is straightforward for a standard deadbolt, taking most users under 20 minutes. The lock body is made of zinc alloy and feels substantial. The Eufy Security app is intuitive, allowing for easy management of access codes and schedules. The lack of Apple HomeKit support is a notable omission for some users, but it works well with Alexa and Google Assistant.

The T8501 is the entry-level model that focuses on core functionality. It uses a basic numeric keypad and Bluetooth for local app control. Many owners report getting over 10 months of battery life from a set of AA batteries. The lock is physically identical to the more expensive models, sharing the same zinc alloy construction and ANSI Grade 2 rating.

The primary trade-off is the lack of a fingerprint sensor and built-in Wi-Fi. To control the lock remotely or use voice commands, you need to purchase the Eufy Wi-Fi Bridge separately. For users who primarily want keyless entry via a code and occasional app access at home, this is an excellent value proposition that saves significant money.

The S330 is a unique product that replaces both your deadbolt and doorbell. It features a 2K camera with a wide field of view, two-way audio, and a keypad on the front. Owner reviews praise the video quality and the local storage (via the HomeBase) which avoids cloud fees. The lock itself operates smoothly, and the app allows you to see and speak to visitors before granting access.

The main downside is the physical size of the exterior unit, which is larger than a standard lock. The rechargeable battery lasts 3-6 months depending on camera activity, which is less convenient than the AA-powered models. If you want a single device for door security and video monitoring, this is the most integrated solution available.

The T8500 features a capacitive touchscreen keypad that remains invisible until you touch the lock, giving it a clean, minimalist look. Owners appreciate the aesthetic upgrade over physical buttons. The lock supports up to 50 user codes and offers auto-lock and schedule features through the app. It uses Bluetooth for local control, with the option to add a Wi-Fi bridge for remote access.

Some users in wet climates report that the touchscreen can be less responsive when wet compared to physical buttons. The lock is otherwise identical in build quality to the T8501. It is a good middle-ground option for those who want a modern look and are willing to trade the fingerprint sensor for a lower price than the T8520.

The C220 is Eufy's more budget-oriented model that retains a physical key cylinder as a backup entry method. This is a key feature for users who want the convenience of a keypad but are concerned about battery failure or electronic issues. The keypad uses physical buttons rather than a touchscreen, which some users prefer for tactile feedback. Owner reviews note it is very easy to install and program.

The build quality is slightly less robust than the T-series locks, with more plastic components on the exterior keypad. It lacks the premium feel of the zinc alloy models. For those who want a simple, reliable keyless lock with the security of a traditional key backup, the C220 is a solid and affordable choice.
