SUMNEW Fingerprint Cabinet Lock, Smart Biometric, Fit for Keyless Hidden File Drawer Wardrobe, Child Safety Electric Fingerprint Lock, DIY Wooden Furniture Privacy for Home Office

Let me start by saying that you should keep your expectations at bay: it's a $25 plastic fingerprint lock. It's perfect for keeping things out of reach of children, for example. If you're trying to keep valuables safe from burglars, you need a proper safe and not this product. It would be quite easy for a mildly-skilled adult to open this lock with a simple bent metal tool, or for anyone over 12 y/o with a screwdriver to pry it open, so keep that in mind. Having said that, it works very well after setting up the fingerprints (which is not as hard as some reviewers say it is - procedure below). It also comes with a USB-C key that can be used to unlock it if you have problems (it'll allow any finger to open it once inserted), which looks just like a USB adapter, so it's inconspicuous. Just make sure to keep the key in a safe place (and not inside where this lock is installed, obviously). How to add fingerprints: 1) As soon as you plug the sensor into the lock and install batteries for the first time, the lock will open with any fingerprint. Start by holding a finger on the sensor. The lock will open, then close, and then the LED will stay blue. That means it's ready to program. 2) Repeatedly scan the new fingerprint you want to add (touch and remove) until the LED stays green for longer and then turns blue again. 5 successful scans are needed for each finger you want to add. Note: Make sure to change the position of the finger on the sensor ever so slightly, to make sure it's less sensitive to small changes in finger position. If you get a red LED it means that scan failed or the finger is already registered. 3) Once the LED turns blue (after 5 successful scans), start scanning a different fingerprint right away. 4) Repeat until you scanned all fingerprints you want to register, then just wait for a few seconds and it'll get out of programming mode by itself. Note: If you take too long to scan a new finger and it gets out of programming mode, use an already scanned finger to re-enter programming mode (step 1). This is also how you add more fingerprints later on. If the lock isn't opening with any finger when you insert batteries on it for the first time, I'm not sure but you might be able to use the supplied key to enable any finger, and then reset the lock (remove all fingerprints). Check the manual, there's a reset procedure there with LED colors to watch for. Installation requires low to average skills, mainly because getting the lock itself bolted at the correct height might be challenging for someone who's never done any DIY. Other than that, drilling the hole for the fingerprint reader is easy. Just be careful when drilling through IKEA furniture, because those are basically glued sawdust, so it might be best to drill a pilot hole through and then drill from both sides to prevent it from looking like a bullet exit hole from the other side, which can make it tricky to bolt the reader in place. It works very fast, even though it might require a second attempt every 2 or 3 times. I'm sure if I program the same finger at a different position it'll be much better. But again: it's a $25 fingerprint lock. Only issue I had is that it was missing a couple of screws to bolt the reader to the furniture, but that's not a big deal.

I purchased two of these to add to our nightstands for our home defense items. They were easy to install into our nightstands with some basic household tools. Adding the fingerprints was a simple process. With the ability to have up to 20 fingerprints. I tested out to see if it would unlock at diffrent angles and was able to do so with ease. Our kids were unable to get the nightstands open after installing making our items secure and out of reach of little hands. It functions as it should in a quick manner for us to get into it quickly. The auto lock system is a nice added feature so you never have to worry about it you rembered to lock it in case you have mama brain like me. They feel sturdy and don't feel like they will break with regular use. I feel like this item was appropriate priced.

great little gadget . i bought a file cabinet to go under my new workstation table . it was the only white one i could find with the strict dimensions to fit under , however it didn’t have a lock . i at least wanted one drawer to lock for out of sight paper work from the cleaning person that comes to my house and my kids. this really did the trick , wish it came in a white to match my cabinet however it still looks kinda cool like a mini camera :) the product itself works great. for all the reviews that peope said it wouldn’t register the finger print and anyone can open it , it’s because you are not registering the fingerprint correctly . that part was extremely tricky for me becasue i’m not a technical person however my 11 year old son who’s a computer genius helped me through that process . Don’t drill the hole too big otherwise the fingerprint pad will be too loose on the cabinet and won’t look right . took about an hour from start to finish and lining up the 2 pieces and making sure it matched on properly also took a bit of time and precision . mai definitely took a bit of time to get it to perfection . otherwise , great product and works well for what i need it for !

This product works great just like it says. I'm using it for a medicine cabinet it only took maybe 10 minutes to install just checking measurements and placement really. the actual install was quick. Adding finger prints was easy as well.

Works. Plugs are light I broke one but ac fix it

Worked good the day I installed, now not so much, now not at all. Master key will work for my wife but will not work at all for me. Now I have a hole in cabinet door that will have to be covered by some other lock I find. Problem could be as a mechanic my hands and fingers are rough n textured idk

Versatil y duran muchisimo las pilas.

Great Stuff, Surprised the fingerprint scanner is accurate and reliable.

This lock is actually very good. Works smoothly so far. It makes life very easy and convenient. Need a carpenter to instal it. Good after sales service as well

it open with all finger prints scam

Not bad

Easy to install, battery life is good,low and best price

Basic criteria of a lock is it should be strong and sturdy, this is made of very bad quality plastic and the electronics do not look reliable at all. And the lock does not even fix properly due to its poor quality and the wires are so thin, it will just break. Disappointing product. Amazon should stop Indian companies selling cheap quality Chinese products as their own.
