Electric Drop Bolt Lock DC 12V Fail Safe NC Mode Electronic Door Lock for Access Control Security - Surface Mounted with Time Delay - desertcart.com

Review: Love it - Good lock when working stainless steel door tht is difficult to cut
Review: Sideways: Locking Windows And Patio Doors - 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.

## Questions & Answers

**Q: If this is in a situation where we would not want it to default to unlocked in a power outage situation, can that be disabled?**
A: When I unplug my setup with 3 doors they instantly unlock. It is pre wired for a backup battery, when the power goes out it will still function as normal. It’s a great setup and works flawlessly.

**Q: what remote control and power supply is used with this lock?**
A: here is power supply control: https://www.amazon.com/dp/B06XRVMGDN/

**Q: What's Remote control distance**
A: At least 10 feet probably farther but it's gonna depend on the type of material you're trying to transmit through

**Q: Is there a Bluetooth access control unit?**
A: This unit does not have Bluetooth capability. An external controller with Bluetooth may be available but our application didn’t require it so we didn’t investigate the possibility

### ⭐⭐⭐ Nice but not consistent!
*by S***7 on August 3, 2025*

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.
