## Description

Built-in Wi-Fi lets the DESLOC K221 connect to its app without a separate hub, so you can check door status and lock or unlock remotely. The integrated connection is useful if you want app access without adding another device to your home network.

The lock also offers fingerprint and keypad entry, plus an auto-lock function that secures the door after it closes. Its rechargeable 15,000mAh battery is rated for up to 16 months per charge, based on the product details.

Made from aluminum, the K221 measures 3.23 x 1.42 x 7.56 inches. Its IP65 rating and BHMA Grade 3 certification are listed alongside weather-resistant construction.

## Key features

The K221 combines biometric entry, a keypad, app control, and a latch in one door lock. The fingerprint sensor is described as designed to read a range of fingerprints, including dry, worn, or fine-textured fingers. The keypad provides another stated access method, while built-in Wi-Fi connects the lock to the app over a 2.4GHz home network.

Through the app, you can lock or unlock remotely, check the door’s status, and receive notifications. Since Wi-Fi is integrated, a separate hub is not required. That makes this a different approach from a smart lock that depends on an additional hub, though it does require a compatible 2.4GHz network.

Auto-lock is intended to secure the door after it closes. The app also displays whether the door is open or closed, which can help when checking an entry point remotely. The aluminum body, IP65 rating, and BHMA Grade 3 certification are relevant details for buyers considering a lock for a front or garage entry door, as well as a bedroom door.

## Best use cases

This model is aimed at doors where fingerprint or keypad access and remote app control are useful together. For example, a household could use the keypad for routine entry, fingerprint access for hands-free unlocking, and the app to check the door when away. Its auto-lock feature adds a way to secure the door after it closes without relying only on a manual locking step.

It may also suit buyers who prefer a rechargeable battery to frequent battery replacements. The stated runtime is up to 16 months per charge, not a guarantee of the same duration in every use pattern. For charging, the instructions specify a 5V/2A charger and advise against laptops, low-power adapters, or worn cables.

## Who it’s for

You’ll appreciate it if you want several stated entry methods, remote app control, and automatic locking in one handle-style smart lock. The 2-year product warranty, lifetime component maintenance, and U.S.-based customer support are additional details to weigh when choosing a connected lock.

It may not suit you if your home network does not support 2.4GHz Wi-Fi, that is the specified network band for app connectivity. In other words, the remote-control features depend on meeting that network requirement, while the product also includes fingerprint and keypad access.

## Before you decide

What charger does the rechargeable battery require? The product instructions recommend a 5V/2A charger for stable charging and caution against low-power adapters, laptops, and worn cables. The listing does not state that a charger is included.

Does the lock need a separate Wi-Fi hub? No separate hub is required according to the product details. App connectivity uses built-in Wi-Fi and a 2.4GHz home network.

What access methods are listed? The K221 supports fingerprint, keypad, and app control. The product details also describe auto-lock after the door closes.

## Is it worth it?

The K221 is worth considering if your priority is combining fingerprint and keypad entry with built-in Wi-Fi, app status checks, and auto-lock. Its stated 16-month rechargeable battery life and aluminum construction add useful context, while IP65 and BHMA Grade 3 are the listed durability-related ratings. The key trade-off is that remote app features require 2.4GHz Wi-Fi. If that requirement fits your setup and you want connected access rather than a basic keypad-only lock, the K221 brings those functions together without a separate hub.
