Once lined up properly , it can be used any where and will always work . The best thing about it is if its a door , it will auto close if activated once it detects the door is back due to the magnet positioning themselves correctly Review: Pretty darn good with caution. - This is a good little lock with just one small issue. The issue is the power with which the small bolt comes out. If you have everything lined up perfectly then you will have no issue. However if the door you are fitting it to, has any movement on its own latch when closed. Meaning the door could be in a slightly different position each time it is closed, then the alignment of the bolt and hole on this unit may not align. The bolt has no chamfer on the leading edge to guide it into slightly misaligned hole. Therefore it won't engage. I fitted this to a door which has a metal frame and is panelled inside with wood (my own creation) but like most doors when shut if you push and pull the door there was maybe 3mm of movement. This is enough for this unit to push the bolt out but not go into the hole on the opposite part of the unit, thus not locking the door even though the green "locked" indicator lights up. To get around this, I was able to attach a magnet I had, to the metal frame of the door ensuring the door was in exactly the same closed position every time. Obviously this wouldn't be possible on a wooden door. So before buying this. I would just see how much play your door has in it when closed. Be prepared to have to play about and adjust your normal catch to eliminate any movement if you are going to install this lock. As a side note for my installation I purchased a 12v power supply (looks rather like a phone charger) and a 12v led indicator, I wired these directly to the lock using the red and black wire. (The yellow and white wire were not needed) I then plugged this into a spare remote control socket I had and hey presto I can lock the door without crossing the yard which is where my door is located or more honestly... The wife doesn't have to cross the yard in her dressing gown to lock up at night when I'm at work. The reason for the additional led indicator light? This lock has a light on the unit itself to show when locked, but what if like me you are on the opposite side of the door to the lock? So I positioned the led where it can be seen from the house. If you wanted to and you had an Alexa enabled plug/socket, you could use Alexa to power it on and off (lock/open) rather than using the remote that I have set up. I have Alexa so this maybe something I do in the future but for now unlocking in a morning and locking at night. I'm happy with the remote switch. Once locked it does appear it would take a lot of pressure to break it open. Remember this lock will unlock in the event of a power failure for safety reasons. So if you are going on holiday or are wanting to protect something very valuable then I would suggest using a normal lock in conjunction with this lock . ## Features - 1, NC Mode: Fail-safe type, unlocked when power off, locked when power on. - 2, Installation: unfold install (surface mounted). - 3, With time delay: 0s, 3s, 6s - 4, Wires: red to "NC", black to "GND". yellow line and white line are useless, don't need to be connected. - 5, Suitable For: Wooden door, Glass door, Metal door, Fireproof door, etc. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DW17J3Q | | Best Sellers Rank | 165,118 in DIY & Tools ( See Top 100 in DIY & Tools ) 117 in Dead Bolts | | Brand | LIBO Smart Home | | Colour | Silver | | Connectivity Protocol | Wired | | Control Method | App | | Controller Type | door lock | | Country of Origin | China | | Customer Reviews | 4.3 out of 5 stars 382 Reviews | | Finish | Surface treatment | | Included Components | Electric Drop Bolt Lock * 1; Bag of installation kit * 1 | | Item Dimensions | 15 x 3.4 x 2.8 centimetres | | Item Weight | 581 g | | Item dimensions L x W x H | 15 x 3.4 x 2.8 centimetres | | Lock Type | Electric Lock | | Lock type | Electric Lock | | Manufacturer | LIBO Smart Home | | Material | Metal | | Model Name | L-XXS | | Model Number | L-XXS | | Number of Pieces | 1 | | Part Number | L-XXS | | Recommended Uses For Product | Security | | Recommended uses for product | Security | | Shape | Rectangular | | Smart Home Compatibility | Smart Home Compatible | | Special Features | Electric | | Special feature | Electric | | Style | Modern | | UPC | 192687557844 760934621954 768692650742 760932522994 | | Unit Count | 1.0 count | ## Product Details - **Brand:** LIBO Smart Home - **Item dimensions L x W x H:** 15 x 3.4 x 2.8 centimetres - **Lock type:** Electric Lock - **Material:** Metal - **Special feature:** Electric ## Images ![LIBO Electric Drop Bolt Lock DC 12V Fail Safe NC Mode Electronic Door Lock for Access Control Security System with Time Delay - Image 1](https://m.media-amazon.com/images/I/51VpyGNXQJL.jpg) ![LIBO Electric Drop Bolt Lock DC 12V Fail Safe NC Mode Electronic Door Lock for Access Control Security System with Time Delay - Image 2](https://m.media-amazon.com/images/I/51SWXv99YnL.jpg) ![LIBO Electric Drop Bolt Lock DC 12V Fail Safe NC Mode Electronic Door Lock for Access Control Security System with Time Delay - Image 3](https://m.media-amazon.com/images/I/515rm0w6ClL.jpg) ![LIBO Electric Drop Bolt Lock DC 12V Fail Safe NC Mode Electronic Door Lock for Access Control Security System with Time Delay - Image 4](https://m.media-amazon.com/images/I/61p-hG0HzmL.jpg) ![LIBO Electric Drop Bolt Lock DC 12V Fail Safe NC Mode Electronic Door Lock for Access Control Security System with Time Delay - Image 5](https://m.media-amazon.com/images/I/51UUVcDMkOL.jpg) ## Questions & Answers **Q: Is this really for outdoor use?** A: Sorry, this lock is surface waterproof only. Can't be used at outdoor. **Q: I want to install two of these on the bottom of my electric up and over garage door. Is the bolt mechanism powered or does it rely upon gravity..?** A: It locks in when powered, the moment it looses power the lock pin returns on its own possibly by spring inside. **Q: Can I operate this directly from a switched 12v supply similar to a light switch so the lock can be opened and locked simply by turning the power on** A: If the power supply is DC12V power supply, you can try to connect this lock to the power supply. **Q: Is this able to lock from the outside with the locks on the inside to be able to lock on going out** A: When you give it 12v it locks. If you place a access control switch like a keypad etc on the outside that gives the lock 12v yes that will work ## Customer Reviews ### ⭐⭐⭐⭐⭐ A bargin *by A***R on 16 April 2024* This is very sturdy and good .
