Eufy Smart Lock Touch & Wi-Fi (S330)
Best OverallPros
- Built-in 2K video doorbell with night vision
- Fast and reliable fingerprint sensor
- No monthly subscription for video storage
Cons
- Larger form factor may not suit all doors
- Requires existing deadbolt preparation
The Eufy S330 is the most feature-rich fingerprint door lock in the lineup. It integrates a 2K resolution video doorbell directly into the lock body, allowing you to see and speak to visitors without a separate device. The fingerprint sensor is capacitive and reads prints quickly, even with wet or slightly dirty fingers.
Owner reviews consistently praise the battery life, which lasts around 3-4 months on a single charge depending on video usage. The local storage (no cloud fees) is a major selling point for privacy-conscious users. The only downside is the physical size, which may look bulky on narrower doors.
Eufy Smart Lock Touch (T8500)
Best BudgetPros
- Affordable price point
- Simple Bluetooth setup with the app
- Fingerprint sensor is accurate
Cons
- No Wi-Fi for remote access
- Requires hub for smart home integration
The T8500 is the entry-level fingerprint lock from Eufy that does the basics exceptionally well. It uses Bluetooth to connect to your phone for app control and firmware updates, but lacks built-in Wi-Fi. The fingerprint sensor can store up to 50 prints, which is enough for a family of four plus a few guests.
Most owners find the battery life to be excellent, often exceeding a year on a set of four AA batteries. The lock mechanism is smooth and quiet. The main limitation is the lack of remote access without the Eufy HomeBase, which is sold separately. For local use only, it is a fantastic value.
Eufy C220 Smart Lock
Best RetrofitPros
- Easy to install without replacing the entire lock
- Works with most standard deadbolts
- Compact design
Cons
- Fingerprint sensor can be finicky with dry skin
- No Wi-Fi or keypad included
The C220 is designed for renters or homeowners who want to keep their existing deadbolt. It mounts over the interior thumb turn and uses a motor to turn the lock. The fingerprint sensor is located on the outside escutcheon, which replaces your existing exterior plate.
Owner feedback indicates that installation is straightforward, taking about 10 minutes. The lock is quieter than the full deadbolt models. Some users report that the fingerprint sensor requires a few attempts if fingers are very dry. It is a solid choice for those who cannot or do not want to replace their current lock hardware.
Eufy Smart Lock S230
Best Wi-Fi ValuePros
- Built-in Wi-Fi for remote access
- Touchscreen keypad as backup
- Supports voice assistants (Alexa, Google)
Cons
- No built-in camera
- Slightly slower fingerprint read than S330
The S230 is the middle ground between the budget T8500 and the premium S330. It includes Wi-Fi connectivity for remote locking and unlocking via the Eufy app, as well as a touchscreen keypad for backup entry. The fingerprint sensor is still fast, though not quite as instantaneous as the S330.
Aggregated reviews note that the battery life is good, lasting around 4-6 months with typical use. The lock integrates well with Amazon Alexa and Google Assistant for voice commands. It lacks a camera, so it is purely a lock, not a doorbell replacement. For those who want remote access without paying for a hub, this is the best value.
Eufy Smart Lock Touch Pro (T8520)
Best KeylessPros
- Includes a physical keypad for backup
- Very affordable
- Easy to install
Cons
- No Wi-Fi or remote access
- Keypad can be less responsive in cold weather
The T8520 is a budget-friendly option that adds a keypad to the fingerprint experience. It is essentially the T8500 with a numeric keypad on the exterior, giving you two ways to unlock: fingerprint or PIN code. It still relies on Bluetooth for app connectivity, so remote access requires the Eufy HomeBase hub.
Reviews indicate that the lock is reliable for daily use, with the fingerprint sensor working well for most users. The keypad is backlit, which helps at night. Some owners in colder climates note that the keypad buttons can be stiff when temperatures drop. For a simple, keyless entry solution without the need for Wi-Fi, it works well.
What to Check Before Buying a Eufy Fingerprint Door Lock
Before purchasing, measure your door's backset (the distance from the edge of the door to the center of the deadbolt hole). Most Eufy locks fit 2-3/8 inch or 2-3/4 inch backsets. Also check your door thickness; Eufy locks typically fit doors between 1-3/8 inches and 2 inches thick. Ensure you have a standard single-cylinder deadbolt, as some older doors may require additional drilling.
Mistakes to Avoid
One common mistake is assuming all Eufy locks have built-in Wi-Fi. Models like the T8500 and C220 only use Bluetooth and require a separate HomeBase hub for remote access. Another mistake is ignoring the battery type; rechargeable models (S330, S230) need periodic charging, while AA models (T8500, C220, T8520) are easier to swap but create more waste. Finally, do not skip registering your fingerprints properly; enroll the same finger multiple times from different angles for best recognition.
