One of the reasons I picked the WELOCK smart lock was to avoid the headaches caused by lost physical keys, especially since my rental guests frequently misplaced them. The variety of unlocking options makes it versatile and user-friendly.
Why Choose the WELOCK Smart Lock?
The decision to upgrade to a smart lock came after years of dealing with lost keys for my Airbnb. Traditional locks require physical keys, which can easily be misplaced or duplicated without permission. The WELOCK smart lock offers a modern, secure alternative that eliminates these issues through:
- Keyless entry options: Use keypad codes, RFID tags, or a smartphone app to unlock your door.
- Remote management: With an optional Wi-Fi bridge, you can control and program the lock remotely, including integration with Alexa, Google Home, and Home Assistant.
- Emergency access: Physical keys and a USB power port provide backup options in case of battery failure.
- Adjustable components: Fits a wide range of door types and hole sizes, making it suitable for most homes and rental properties without extra modifications.
- Durable construction: The lock features a heavy stainless steel body with a sleek black finish, offering both strength and style.
Overall, this lock provides peace of mind and flexibility, especially for rental hosts like me who want to control access without the hassle of managing physical keys.
Installation Made Simple: A Step-by-Step Guide
One of the standout features of the WELOCK smart lock is how easy it is to install. You don’t need to be a professional locksmith or have specialized tools. Here’s how I installed it on my door:
- Remove the old lock: I started by taking off my previous standard lock, which was quick and straightforward.
- Insert the adjustable lock barrel: This piece fits into the existing hole and adjusts to the correct length based on the distance between the door and the handle. This eliminates the need for drilling new holes.
- Screw in the lock barrel: I secured it tightly to ensure stability.
- Attach the keypad unit: I pushed the keypad through the door hole and fixed it in place with the provided screws.
- Install the inside handle: Using the screws included, I fastened the interior handle to complete the lock assembly.
- Install batteries: Using the small screwdriver and the blue plastic tool, I popped open the battery compartment and inserted four AAA batteries.
- Seal the battery compartment: I replaced the cover and secured it with screws for a neat finish.
It took me less than 30 minutes from start to finish, and the lock fit perfectly into the existing door setup without any modifications. If you’re unsure which model is best for your door, the WELOCK team is very helpful—you can send them a photo of your current lock setup, and they’ll recommend the right model for you.
Programming and Unlocking Options
Once installed, the WELOCK smart lock offers multiple ways to unlock your door, making it extremely versatile for different users and scenarios. Here’s a breakdown of the unlocking methods and programming features:
Keypad Entry
The primary method I use is the keypad. You can program up to 10 user codes through the smartphone app or directly on the keypad. This allows you to give unique access codes to each guest or family member, with specific start and end times for when the codes are active.
For example, I send a code to my Airbnb guests that only works during their stay, so they can come and go as they please without worrying about losing keys or security.
Smartphone App Control
The companion app connects to the lock via Bluetooth when you’re near the door. You can unlock the door with a simple tap on your phone. This is perfect for quick access without entering codes. The app also allows you to manage user codes, view access history, and configure settings.
If you want remote control from anywhere, you can purchase the optional Wi-Fi bridge. This device acts as a bridge between the lock and your home Wi-Fi, enabling you to lock or unlock the door remotely and integrate with smart home assistants like Alexa and Google Home.

RFID Tags
Included in the kit are three RFID tags that you can program and distribute to trusted users. Unlocking with an RFID tag is as simple as tapping it on the top of the lock. This is a convenient alternative for family members or frequent visitors who prefer not to remember codes or carry their phones.
Physical Keys and Emergency USB Power
While the lock is designed for keyless entry, two physical keys are provided for emergency access. These keys are stored behind a rubber cover on the back of the lock and used only if necessary.
Additionally, if the batteries die, there’s a USB port where you can connect a power bank to temporarily power the lock and gain entry. This thoughtful design ensures you won’t ever be locked out due to power issues.
Temporary Passwords for Remote Access
One of the most powerful features is the ability to generate temporary passwords through the app from anywhere in the world. This uses a time-based algorithm to create a code that works only during a specified time window.
This is perfect for Airbnb hosts or anyone who needs to grant access remotely. You don’t need to be near the lock or have the Wi-Fi bridge installed to use this feature. Simply generate the code, send it to your guest, and they can unlock the door with it during their stay.
Additional Features and Benefits
The WELOCK smart lock isn’t just about unlocking and locking—it offers several additional features that enhance security and convenience:
- Access History: The app keeps a detailed log of every entry and exit, showing who opened the door and when. This is invaluable for monitoring access to your rental or home.
- Multiple User Management: You can manage multiple users with different access codes or RFID tags, each with customizable permissions and time restrictions.
- Auto-Lock Function: You can set the lock to automatically engage after a set period or during certain times of the day, ensuring your door is never accidentally left unlocked.
- Sound Control: The keypad beeps on entry, but you can disable the sound if you prefer a quieter operation.
- Long Battery Life: The four AAA batteries typically last about a year under normal use, making maintenance minimal.
These features make the WELOCK smart lock a comprehensive security solution, especially for rental properties, family homes, or any situation where controlled access is important.
Final Thoughts: Is the WELOCK Smart Lock Worth It?
After using the WELOCK smart lock for some time, I can confidently say it delivers on its promises. The quality is excellent, the installation is straightforward, and the variety of unlocking methods gives you real flexibility.
