WOOCH RFID Locks for Cabinets Hidden DIY Lock - Electronic Cabinet Lock with USB Cable for Wooden Cabinet Drawer Locker Cupboard Gun Box (1 Pack)

They work great, but they only came with one set of directions, and I install these for customer products, which doesn't give me the opportunity to leave directions with each customer.

The order arrived very quickly but the latch , battery cover, usb cable and sticker was missing, no instructions whatsoever in box. Contacted seller and a refund was processed immediately, props for this only.Seller did not claim the original package, I nevertherless installed batteries to see if the unit works, but it seems defective, only beeps and does not unlock, reset button also defective.So buyer beware.

Not usually one to write reviews but figured I’d write one for this if you’re in a position I was looking for a solution. I ordered these to attached to an ikea cabinet which I would be using to store items I did not want guests or maintenance entering my apartment to accidentally come across.Ease of Installation: Installation is really straight forward, like really straight forward. If you have any semblance of common sense you will have zero issues installing it to a cabinet, drawer etc.Ease of programming: Again, ridiculously straight forward, programming a master key for the two locks I purchased, then individual keys for each lock took me less than 10 minutes. All it takes is following simple 1,2,3 instructions. Programming is a little more involved if you want to use the advanced features (dual key access) but still easy enough.Durability and functionality: Had mine for roughly 2 weeks now, opening and closing each cabinet door several times a day with both the master key and the individual keys, not one issue has appeared. Locks do not shift nor do they need to be adjusted as long as you use the included hardware. And this is with my both slamming the cabinet door shut on my way past it and gently closing it. Its been handled gently and abusively and has stood up to the test with zero issues.Battery Life: Can’t speak to that but like I said have had one of the locks for two weeks opening several times a day and not a problem yet. The instructions mention that once battery is low you will hear an audible long beep after opening it at which point you should soon after replace the battery. Then it will pop open on its own to avoid locking itself with dead batteries.Overall its a great little security feature for 12-15 bucks.

I purchased 2 of these to secure a couple of cabinet doors from the grand kids. I have some upper cabinets where I store ammunition and other gun related stuff (cleaning supplies, ammunition, holsters, cases, extra magazines, etc.) that I don't want the kids getting into. These have worked out well.They of course are not security locks. They would be very easy to defeat for anyone intent on breaking into a cabinet, but to keep casual nosy kids out, they work well.They were very easy to set up. They come with 2 programable key cards and 2 programable key fobs.They operate on 2 AA batteries (not included). In the event of low batteries, the lock will automatically unlock. There is also a USB cable that will allow you to connect to a power source should the batteries go dead and the door is locked for some reason.Installation took some figuring. Trying to figure out the placement of the lock and latch inside a closed cabinet took some doing, but if this old retired prison guard can figure it out, most people should be able to make it work.This turned out to be a very inexpensive way to easily secure stuff I don't want the kids getting into while still allowing me ready access to it as I need.

I am using these in my rental unit in kitchen cabinets for owner access only. They work great. The installation was not bad. I can key all the units the same. USB and battery can be used at the same time. Lithium batteries can be used if you have a 5v power pack.
