Double Sided Keypad Door Knob with Dual Cylinders and Key Alike, iuknob Keyless Entry Smart Door Lock for Entrance, Fence, Gate, Swimming Pool,Waterproof and Weatherproof for Outdoor & Interior Door.

This is a great option for a metal security door. Most keyless locks only work from one direction, so they can't be used one security doors or gates because someone could cut the screen and unlock it. This one was very easy to install and functions well.

Great lock. Easy to install, well built, easy to program.Would like to have seen batteries included and less importantly, it would be nice to be able to orient the keypad knobs right-side-up but they appear to be fixed

The media could not be loaded. A good value and works great for what we needed which was a two sided lock on an internal door in the house. It is easy to program and we like that you can program different settings on either side. You can type in a bunch of different numbers, then your code and it will unlock. I think this is a security feature so if the lock is on an external door on a busy street people watching or walking by won’t know what your true code is. Requires 4 AAA batteries that it does not come with.

I originally purchased three UI-32 locks in July 2023. Two of them have worked reliably since installation. However, one lock has been problematic from the start — the batteries would drain roughly once a month. I reached out to the seller and we tried troubleshooting the issue together without success. In December 2023, they sent a replacement lock, which initially performed better.Unfortunately, about a month ago, the same issue started again: the batteries die within just a few days. I verified that the installation was correct and followed all their instructions. I sent a detailed email explaining the recurring problem and asked if this was typical of the product, referencing other customer reviews that mention battery issues.After that, I received no response — despite multiple follow-ups.The inconsistent performance is frustrating, but being ignored by customer support is even worse. If you’re considering this lock, be warned: quality control is hit-or-miss, and you may be on your own if something goes wrong.

I bought two double-sided keypad locks in 2023. Last month, one side of the keypad on one of the locks stopped working. I reached out to customer service, and even though the lock was beyond its one-year warranty period, the company sent me a replacement. Their exceptional customer service left me very impressed—I highly recommend this lock.A company going above and beyond warranty terms really says a lot about how they value their customers. It’s the kind of experience that makes you feel confident about your purchase and the brand itself.

Worked for me

I bought this locking knob for a gate to my outside courtyard. From the day it was installed, it would not remember the code on both sides. I opened it, made sure it was in the "sync" position and it started working again, but a couple of days later, it stopped working on the external side again. A couple of days later, it started again. I have been locked out twice by this knob and have to carry a key just in case it is a day that it is choosing not to work properly. It defeats the purpose of having a coded knob. I would not recommend this product because of it's inconsistent reliability.

Installed relatively easily on my gate. It is one of the only outdoor locks that has a code for each side. What is disappointing is that the two sides are pretty much independent. With the synch button, I can program a code that will work on both sides, but I cannot seem to program the lock so that once I unlock it from one side and program it to stay unlocked for 5 minutes, that it also remains unlocked on the other side, which would be really useful for when I need to run in and out of the gate quickly to take the trash out for example.The other major draw back is that there is no option to program the gate be unlocked during certain times. I know the lock keeps track of time as this is what it uses to provide remote access codes. It would be so useful if it would lock the gate at night and unlocks it during the day.
