It certainly can! Please keep in mind that this is a deadbolt and not a code entry handle. If you are looking for a similar double-sided handle set, please check out the Lockey 3835DC!

I had a lock smith install it for me on my cedar fence gate. I really love it. So easy to use and maintain. Having keypads on both sides is a great UX, and the ease of just turning the knob to re-lock without needing to type in a code to lock it is really simple. Provo designers and engineers!

Easy to install, followed the template to drill the holes. Was able to change the kog things with ease to make my own key code. I know can let me son play without having to worry if he will elope and get hurt.

This is not a perfect system, but it solved the one need I had which is open iron work on my gates, we have two of them. It was east for people to reach through the gate to get to the handset with my old setup and open the gates.
This is a mechanical system, so easy to set up and use, but because it is manual, we have to clear it before use, not a big deal, one more button, but a electronic set would clear after a time away, I assume. What I wanted was a smart lock, like I have on the entry doors to the house, but no one seems to have a reliable outdoor model.
if you are in the same situation as me, open ironwork, and no smartlock available, this is the best set up you can get.

I purchased and installed the Lockey 3210DC on my outside gate. The lock itself is quality, fully mechanical, easy to re-program, and has a nice feel to the keying and deadbolt action. It works well. The only reason it’s not full 5 stars is that it appears to be somewhat less sturdy and possibly easier to break/rip off compared, for example, to the old Schlager I had in place. The Lockey’s both halves/sides are connected and held against the door frame with two relatively small gauge screws, and furthermore there are black rubber spacers between each half and the door frame, presumably for weather sealing. These spacers effectively create a soft gap between the lock and the door frame, which could be straight forward to exploit by sliding a pry bar into it and ripping the lock off by breaking the connecting screws. For comparison, the old lock metal body was flush against the door frame, and the connecting screws were heavy gauge, making the whole thing considerably harder to compromise. The deadbolt itself is plenty sturdy and not a problem, and the weakness in this case seems to be in the way the lock body is mounted. So in my case, the Lockey provides more convenience and functionality, but a bit less security overall, which is fine for an outside gate, but could be an issue for other locations.

I’m happy with the keypad entry. It was a great addition to my home. Good quality and can with stand humid temperatures.

This was a new product for my experienced locksmith to install. He was skeptical, because he’d never seen your brand before. We installed it on our gate which needed both sides accessed while adding security. My locksmith was very impressed with the product and found it very easy to install. We are extremely happy with GoKeyless!

The 3210DC and 3230DC locks with the double sided keypad are excellent for use on gates to prevent un-wanted entry from either side. The locks install easy and are easy to set the code.

I am an architect, and therefore try to plan ahead more that a lot of construction people. I have not yet built the gate and installed the hardware. I have looked at the products, and they appear to be everything I hoped for.

I recently purchased my second keyless gate lock from GoKeyless. I had purchased the first one – a Lockey 3210DC, several years ago, and have found that I couldn’t do without it. It has performed flawlessly, and weather has had no effect. So I ordered another one for my second gate. Ordering online was easy and it shipped quickly. Thanks again for a great product and excellent service.
