What Buyers Say
Users frequently highlight the straightforward installation process, often completed with just a screwdriver in minutes, and the convenience of the 50 user codes. The auto-lock feature is a recurring positive, preventing accidental unlocked doors. Many appreciate the robust, waterproof construction, making it suitable for various outdoor applications. However, the lack of any smart app functionality or remote control is a consistent point of clarification, as some buyers expect more 'smart' features from a product labeled as such. The need for careful gasket placement during installation for full waterproofing is also noted.
“I just wanted a simple code lock for my garage door, something that wouldn't freak out in the rain, and this thing does exactly that, no fancy apps to mess with, just punch in the code and it works, finally no more fumbling for keys in the dark.”

Frequently Asked Questions
Does this lock connect to Wi-Fi or a smartphone app?
No, this iulock keypad door knob does not have Wi-Fi or Bluetooth connectivity, so it cannot be controlled or monitored via a smartphone app. All programming is done directly on the keypad.
How many user codes can I program?
You can program up to 50 unique user codes, each between 1 and 15 digits long.
Is this door knob waterproof for outdoor use?
Yes, it has an IP65 weather resistance rating and is designed to work in extreme temperatures from -22F to 176F, making it suitable for outdoor installation.
What happens if the batteries die?
The lock has a low battery alarm. If the batteries completely run out, you can use the included mechanical keys or power the lock temporarily via its Type-C USB backup port.
Are the keys for all 8 knobs the same?
Yes, this specific 8-pack is designed with a 'key alike' feature, meaning one physical key will open all 8 door knobs.
Buying Guide
When you're looking at smart door knobs, think about how you actually want to use it. Do you need to unlock your door from your phone when you're not home? Do you want to see who's coming and going? Or do you just want to ditch your keys and use a code? This iulock knob is for that last one – it's a keypad lock, not a connected smart home device. It's about convenience at the door, not remote control.
User Code Capacity (50 codes)
This tells you how many different people can have their own unique code. 50 is plenty for a large family, rental property with many guests, or a small office, allowing you to give temporary access without sharing your main code.
IP65 Weather Resistance
This rating means the lock is protected against dust and water jets. If you're putting it on an exterior door, a high IP rating like 65 ensures it won't short out or corrode from rain or humidity, unlike indoor-only locks.
Type-C USB Backup
Imagine your batteries die and you're locked out. A USB backup port lets you temporarily power the lock with a portable battery pack, so you can enter your code and get in, avoiding a lockout situation.
Alternatives
If you need to control your lock from anywhere, look for models that specify Wi-Fi or Bluetooth connectivity with app support. For advanced security, search for locks with fingerprint readers or integration with smart home hubs.
