Nice but not consistent!
Item worked great for a little while then all of a sudden wouldn't unlock. So I replaced with a new one and only lasted 2 weeks then same thing. But I also installed 1 at another location that is still working so I guess it's the luck of the draw.

You need more than this device
I purchased one of these devices and unfortunately, it did not function as intended. The device is supplied with four wires. While it is expected to have a power battery input, the other two wires are also necessary for operation. However, unless the manufacturer provides a wiring diagram that clearly specifies all the required connections, I would not recommend purchasing this item for locking purposes. It is already expensive on its own, and if you need to purchase additional controllers or components to make it work, the cost will be even higher. ... show more

Sideways: Locking Windows And Patio Doors
Review Image by TM

This is a relatively affordable electric drop bolt. What it does: A magnet pushes the lock outside as soon current is applied, if the counterpart is aligned with the locking mechanism. With no power, the bolt snaps back. That’s a fail safe option, so doors can be opened in case of a power outage. Ideally there should be backup power to keep them operable, to prevent a major unlock during a blackout. The quality is okay. I wouldn’t use these for doors. They don’t seem sturdy enough to withstand strong lateral force, like a kick or hit. There are better solutions that are able to absorb a shock. In my opinion they are great for sliding elements, like windows and patio doors. With a safety film applied to the glass, this creates an effective layer of safety. It takes a lot to remove or disengage these from the outside. Time is a factor. The longer it takes to enter, the more likely a burglar will abort trying to get it. Depending on preference, there are two ways how to use them: 1. A momentary switch to disengage and open, the lock will engage automatically when closed. 2. A switch to engage. Switched off the lock will remain open. Option 1 is easiest to wire and is more fool proof. Number two is better if a centralized system manages multiple locks, for example when leaving the house. In its most basic setup only two wires (red and black) will make this work. The two other ones provide feedback about the status of the lock by the position of the bolt. Adding an Arduino to switch and sense is a very doable project and a really cool feature. Anyways: A switch, a 12v battery, and a charger tucked away will do for a minimum setup. There are some sweet power banks and backup units available for security cameras, some even with solar panels, for quick results and minimal wiring. (There are specific power supplies for door locks and magnets, but I want to keep it DIY friendly) I used a router to create a recess in the window trim for the lock and wires. Any woodworking chisel and sandpaper can do the same, probably even more accurate. Make sure both parts are aligned precisely, There is a bit of tolerance, but that’s more slack for the bolt than room for adjustment. I found it to work best to install the catch with the bolt extended. Double sided tape helps to test before bolting it down. Nobody wants to turn a window frame into a swiss cheese. I took a few photos from my install when I was halfway through and a scan of measurements that come in the package. The cable colors are not documented, but are universal. I hope this helps to make a decision. ... show more

Lock testing issues
Make sure to place the part the lock goes into next to the lock before testing it. There is a proximity sensor that detects that part of the lock, otherwise, it won't lock.
