Yale YRD420-F-BLE-BSP Smart Biometric Fingerprint Door Lock - Keyless Entry with Touchscreen Keypad & Fingerprint Scanner - No WiFi Required - Matte Black Finish - Perfect for Homes, Apartments & Offices

I recently bought and installed two Yale Assure Lock 2 Touch door locks. I elected to get the keyless version with Bluetooth only.It doesn't take too much searching to find plenty of YouTube videos that show how easy it is to defeat conventionally keyed locks. So right off the bat, going keyless was a step up in security. I chose the Bluetooth-only option mainly to keep battery drain to an acceptable level. But it's also the case that I have no need to remotely activate my locks or view their status - never had it and don't need it. On the other hand, without a Wi-Fi-enabled lock you lose geofencing capabilities and remote/timed entry for house cleaners, dogwalkers, and guests.Here though, something that isn't mentioned (or is easily missed) in their sales info is that Yale does not recommend using keyless locks if you only have one entry door because you can be locked out if there is a lock failure. That warning appears in the user's manual.But with the Assure Touch, there are three ways to open the lock: finger touch, keypad code, or with the app if you are within Bluetooth range. And if the batteries go dead, you can touch a 9-volt battery to contacts on the underside of the keypad to enable the lock. So there is plenty of built-in redundancy. It seems like the only failure mode would be if the actual motor-driven locking mechanism somehow broke or jammed. But there is redundancy there if you have these locks on more than one door since the chances that two locks would fail at the same time is probably highly unlikely.Installation was relatively easy but if you don't know what end of a screwdriver to pick up or are intimated by putting together Ikea furniture, it might be a challenge.My main issue came after installation. The user manual is very good in explaining the installation but not so much with getting the app up and running. After install, the manual just tells you to follow the instructions on the app on your cell phone. But I found it like following a road detour and suddenly there are no more signs to follow. I did not find either the app or user manual documentation to be forthcoming in telling you how to configure the lock and how to add other people. You can grant access to other homeowners and guests but it's not immediately clear how. I suppose there is always Google there to help, but at least at the time of this review, there is a 24/7 Yale customer hotline that proved to be quite responsive and helpful.But after you explore the app and get used to it, it offers a lot of functionality. I opted to install the Yale DoorSense hardware (which is nothing more than a little magnet) that lets the door "know" when it is opened or closed. This enables to door to automatically lock at a time delay of your choosing. So there's no more I-wonder-if-I-locked-the-door anxiety when you leave. You can also program in the number of tries someone gets to guess your keypad entry code before getting locked-out for a period of time that's also programmable.But the best part of the lock is the touch entry. It is amazing. You just have to touch (importantly, not press) the finger of your choice on the fingerprint reader and the lock opens instantly (you LOCK the door using any finger). Easy and convenient.This is a well thought-out lock that looks great and is easy to use. I very much recommend it. The only thing left to be assessed is how well it performs over time in regular use. But my immediate impression is that they are very well made and likely to go the distance.
