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

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

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.

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.

pretty neat

This is a cool little gadget that you can use to lock a small drawer or cabinet door. Just don't expect it to serve as a security device. While both pieces can be screwed into wood to hold them in place, a swift yank will rip them right out. It comes with multiple RFID keychain style tabs and credit card sized RFID cards as well. I was never able to get them to program more than one of the RFID cards at a time, so I had one that works and a stack that are useless. I would strongly recommend also buying a USB cable that's long enough to reach a plug or charging bank as a back up. When the batteries are close to dying the unit will alert with a tone and unlock itself. Once they are completely dead the until will remain locked and the only way to unlock it is to replace the batteries or plug in the USB cable to power. If its in a space that is not reachable from the outside, this is a major problem. This happened to me multiple times and the last time I had no choice but to pull the sliding cabinet door until the screws broke loose. The best application for these locks is hidden drawers or cabinets. They are very popular for DIY hidden valuables (guns, cash, jewelry, etc.) cabinets and drawers where the storage space remains hidden until the RFID tag is waved over the lock from the outside. The RFID tag only works through about 1/2 inch max of particle board or plywood. I doubt it would work beyond that 1/2 inch through any material or a hardwood at all. I eventually gave up on it because of the issue with it locking when the batteries died and not having a plug close enough to use the USB option.

This is a well priced, nice little lock, which works with fobs and cards, and is "relatively" easy to set up. There is one big issue, however, and that is that you cannot set it to remain in an unlocked position - in other words, it automatically closes after about 5 seconds. This means that if you want to lock this drawer only SOMETIMES, overnight perhaps, or when access is available to strangers, etc., you can't, and it also means that when you use the drawer personally and any time, you must unlock it and close it shortly after opening, or you can't fully close the drawer. In other words, if you close it with the automatic lock functioning, the drawer, or course, can't be closed fully because the lock section is locked, thus not allowing the drawer to close fully. So this would be good for an office, or such, but in a personal function only, it is limited, and doesn't work for those who want to intermittently lock the drawer, cabinet, etc. I asked the manufacturer to confirm this finding, which they did, and they did immediately - so other than this issue, the lock works. Just be aware that you can't leave it in an unlocked position for more than the time it is programmed to automatically lock itself.
