RFID Lock Electronic Cabinet Lock, Hidden DIY Lock with USB Cable for Wooden Cabinet Drawer Locker Cupboard (1 Pack)

Overall I give this product a five for function. It is a good lock and well worth the cost. As far as it being easy to install that depends on the application I suppose. In my case I am using it for a shelf which has a hidden compartment that drops down. In this application lining up the latch with the holding mechanism is super tricky because the angle at which the compartment closes has to be accounted for and it’s not just a matter of simple math but rather a lot of trial and error and really small micro adjustments until you get it exactly right. When you finally get it right it works like a charm and is worth the effort. The other issues I had was that only 1 of the 4 cards that came with the pair of locks was able to be programmed. All of the key fobs worked though so it wasn’t an issue. The one recommendation I would give to the manufacturer would be to make the wire lead longer on the lock. It was too short to be of any use in my application. There was simply not enough wire to extend it anywhere that would have made it accessible once the shelf is locked. Had it been 6 inches longer I could have extended it to a place where it would have been accessible and concealed. Not a knock on the product just an idea to make it more usable for more applications. Like I said before I still have to give it five stars based on function and overall value.

Works exactly as described. Installation is quite easy. Great value for the price

It works, but the performance is inconsistent. One of the locks I have actuates pretty well, the other one not nearly as well and can't handle any tension force on the mechanism. The mechanism is sensitive to the force imposed on the lock in all directions. If there is too much force on the mechanism inward (OR outward), it will not actuate properly and release the bolt when unlocking. Therefore making the installation tedious to get the right amount of force to oppose the lock, if you want the door to spring open. This doesn't matter much with a typical desk drawer, where it doesn't need to be perfectly flush or be under tension, but it does matter hugely when trying to use this on a flush panel under some tension so it springs open.I think this is a manufacturing issue. The piston and the cylinder bolt which it captures are cheaply machined with sharp edges not sanded off and they bite into each other when locked and force is exerted on them. This causes the mechanism not to release cleanly, because it can't overcome the friction caused by the metal edges with it's tiny motor. Lubrication won't do anything, but with a small metal file and a little time, you might be able to smooth out the contact points so it actuates more cleanly.

I originally saw this product on FB for $140, then it was on "sale" for 50% off. Amazon sells the exact same item for $15, so it was worth trying it. Works as advertised, it can be a little tricky to get it lined up since it is inside the drawer, but it will still work even if it is just a little off. I doubt it would hold up to extreme force, but it is perfect for keeping young children out of cabinets or drawers. It is easy to hide the fob nearby and even if someone fines the fob, it would not be obvious how to use it unless you know where the latch is located.

pretty neat

Update 1-30-2025. After contacting the manufacturer, and repeatedly trying different techniques to get them to open, the locks kept us from our cabinet contents for over a month! Finally had to break into them, then have the cabinets repaired, and repainted. HUNDREDS of DOLLARS worth FAR MORE than these CHEAP PIECES OF @%$@#$% ..... What's worse, even as cheap as these were, the seller/manufacturer essentially e-shrugged, and said sorry, nothing more we can do to help. So, given the worthless support and the eventual failure of these, I'm reducing my rating to a ONE-STAR ... since zero stars are not available! (As a replacement, I've switched to magnetic locks -- MAGNETS cannot fail, and am very happy with our new system of securing our liquor and medicine cabinets.)--- ORIGINAL REVIEW ---Really wanted to give this a 5-star as the concept is great. First though, you should know that it's REALLY difficult to install. My carpenter and I worked for hours each time, installing a few of these to get them right. There's no way to adjust the two pieces to line them up better once the screws are drilled - so plan and drill CAREFULLY, but it's still very difficult. Second, once they're installed and working, I actually would absolutely give them five stars -- and would have probably given them 4-stars because of the installation time, that is -- until the batteries started running low after a few months. At this point, with two units now, the batteries must be low, as they are making a ticking sound, but remain locked & WILL NOT open with the RFID card!!! Will it eventually open? I don't know!!! Don't really want to destroy my custom cabinets trying to open them. How long before I decide just to destroy the lock and rip it open? Again, I don't know but the cost of fixing once torn open will be far more than the cost of these units!!! Hence, the two-star. Gets one star for the concept, and one for working well for a few months, but am really regretting getting these now. The invisibility is great, but if they fail to work right ... VERY frustrating!
