## Description

⚠⚠⚠ WARNING ❗❗❗ This is NOT an automatic dead-bolt lock ! After pressing a valid code, you have ONLY 3-sec (indicated by a 3-sec long beep) to TURN the keypad knob to unlock! If you don’t turn the keypad knob within this 3-sec, the lock will be back to the “lock position.” This is a security feature "auto-lock" designed to prevent “forgetting to lock.” This is a spring latch lock. The latch does NOT have motor and does NOT move itself. Therefore, it lasts longer than dead-bolt. Again, you will need to TURN the keypad knob to unlock. Install this door knob yourself! Everything included: you just need a screwdriver, no professionals needed (saving on contractor costs)! Don't worry about losing, forgetting, or making extra keys time and time again. Fits in standard door knob installation hole. You're free to add, change, or delete user Codes. This lock works for exterior, interior, side, or garage entry doors. For Family: Each member can have their own user code to access. Coming home late at night? No problem. The keypad is lit up by LED when pressed, so you can see it in the dark. If relatives are visiting, set a temporary code for their stay. No spare keys needed. Going for a jog or a ride, no more carrying a bulky key chain or worrying about losing your keys along the way. Press your code and you are home. Pet lover: This lock will allow you to give your neighbour or pet sitter an User Code of their own while you are away. When you return, simply delete the code from the lock. For Airbnb, rental or vacation home owner, this will reduce your costs in replacing locks and making extra keys. Install this lock on your rental property and save yourself the hassle, too. When your renter moves out, simply delete or change the code. Please Note: While this door knob is designed for operational temperature from 6-degree F to 102-degree F in outdoor and indoor applications, it is recommended to be under a porch or some kind of overhead cover, and it should NOT DIRECTLY to be exposed to heavy rains or accumulated snow or melting ice. Please refer to photos in the listing and to our web site FAQs

Review: Really impressed. - I bought this lock for my home office door. I sometimes travel and need to be able to lock it while my house is being taken care of by others. It went in pretty easily. I like being able to put in eight combinations/passcodes. I also like being able to leave it unlocked. To someone who doesn't know the lock it still appears to be locked but a user knows that all one has to do is touch one key to open in this mode. So, I leave it this way most of the time and if someone breaks into my home, it will appear to be locked. Super cool. This lock is very sturdy and operates smoothly. NICE. I was very surprised. Great value for the money.
Review: Read this one! - I bought two of these security key door knobs over two years ago. They’re worth every penny spent. Plumbers and flood damaged floors are expensive fixes. Our purpose of installing these was to keep our ASD kiddo out of our bathrooms unsupervised. Everything about this product has worked well. Battery last a long time, easy to install, size fits a standard small inside door and it doesn’t fail. The only issues we’ve ran into were user errors. Like the time my spouse left the door open and chaos followed. Or the time I accidentally programmed one of the door knobs wrong, because the kid figured out the code and I had to reprogram both of them… So about that! I noticed one of the knobs was allowing entry with partial code input. I thought it was broken and reached out to the company. Excellent costumer service! The video I sent was seen by their tech team and they were able to explain that it was user error on my part. To just reprogram it because I had accidentally put it in passive mode. The fact that they were so prompt in their response and helpful I appreciate immensely. For me a company that stands by their product and is responsive to their customers makes it worth everything! Takeaway: I would absolutely buy again. Just don’t be like me and loose the instructions and go off your memory if you’re reprogramming the code. You may do it wrong, but at least this company has your back as they did send me a digital copy of the instructions. This shows how easy installation is though, because I was able to remember (2 years later even) the sequence to program it and one out of the two knobs was working fine. I’d give this product and its company more than 5 stars if I could. Highly recommended

## Questions & Answers

**Q: can I disable the auto lock feature?**
A: "can I disable the auto lock feature?" - short answer is "NO!" This is a designed security feature to prevent "forget-to-lock." The knob will be back to "lock" position automatically after 3-second of a valid code entry. For frequent open-close-door, you may either use "latch stopper" included in the package, or set P-mode "Passage" with 1-touch unlock without the need of access code. This is NOT a dead-bolt: when you press a valid code, you need to TURN the keypad knob to unlock within 3-sec while beeping! This is also a security feature "auto-lock" to prevent from "forgot-to-lock." This is a spring latch lock. The latch does NOT have motor and does NOT move itself. Therefore, it lasts longer than deadbolt. Again, You will need to TURN the keypad knob to unlock.

**Q: What if you are using this on an inside door and the door shuts behind you. Will you be locked in?**
A: If you install it so that the keypad is facing inside of a room, then yes, the door shutting behind you would require you to input a code to turn the handle and get out of that room. The other side (no keypad) turns and can open the door at any time (without inputting a code). Installing it facing into a room seems unlikely. Most likely, you would be installing it with the keypad facing out of the room; in which case, you would not be locked in if the door shuts while you are inside the room.

**Q: Can you mute the beeping?**
A: Q: How can I turn off the beep sound?
​A:  The lock does not have a switch to turn off the beep sound. Some customers told us that to lower the volume they used sticky tapes to cover the holes on the lock or even use silicon glue to seal them off. But we definitely do NOT recommend this as the beeps are designed to not only provide a security alert for every access attempt, but also function as low battery level warning when the batteries inside are about to run out.

For more info, please read FAQs.
===

**Q: Will this works with a conversation kit for mobile home**
A: NO! This is NOT a connected lock. More secured: no phone, or wi-fi connects, or internet connects; no cyber hacking.

### ⭐⭐⭐⭐⭐ A Decade Of Faithful Service
*by M***N on October 26, 2025*

I've been using the previous version of this lock multiple times a day for around 10 years without fail. I would still be using this lock if I hadn't been too lazy to change the batteries and left the battery pack in the room I unlocked. In the decade of service, it never once failed to secure the room or unlock (as long as it had battery power). The battery life varied from lasting about a year to slightly less, depending on the brand. It gives you plenty of warning when the battery pack is low, so the mishap is all my fault. The keypad is easy to read in any light condition and never failed to light up. I had to actually cut the keypad off with a Sawzall to get it open, and that took five minutes, so the lock is durable. I replaced my old lock with one that is only five years old, and I have absolutely no worries about security or function on any permutation of this excellent lock.
