Yale Security Assure Lock 2 Deadbolt, Satin Nickel Smart Keyless Entry Door Lock with Z-Wave Connected Keypad for Code Entry, YRD450-ZW2-619

This sleek looking lock not only looks great on my new steel entryway door but it is also quiet, easy to use and boasts plenty of useful features. The Yale app is pretty good and set up was easy. You can set up multiple codes, time of day access, notifications etc. I was also able to easily integrate it into my SmartThings network. The installation was straightforward and instructions were clear and simple. One of the most useful features is the auto-lock, which my old Schlage lock also had, but this lock comes with an open/closed door sensor which prevents the auto-lock from locking the deadbolt if the door is open or left ajar, saving the door frame from damage. There's also a button on the inside that overrides the auto lock for when you want to close the door but leave it unlocked for people to come in and out (e.g. workers). Super convenient. I had to enter a code and perform a sequence of steps with the Schlage lock, which was not if a pain. I haven't tried the auto-unlock feature. Lastly, I choose the keyless lock because in the years that I owned the Schlage lock (which I moved to another door) I never once needed the key. I hope this doesn't come back to bite me.

The unit works great. I love the minimalistic design and quiet operation. I linked it to Ring hub with the ZWave module. There is a Yale app as well. Super convenient for kids coming in after school. Easy to open from the outside, there is a nice audio feedback. The installation went fairly smooth - be sure to look at the dimensions in the instruction manual to make sure your door fits. They provide different lengths of screws for common door sizes. There is one backup physical key, I put that in a safe place and haven't had to carry it with me.

Mixed feelings about these Yale smart locks. The physical product is solid - installation was straightforward and the build quality is good. The fingerprint reader works decently (though not perfectly) at about a 75% first-try success rate.The major letdowns are all software-related:The Yale app is frustratingly basic and poorly designedHaving to register the same fingerprints separately for EACH lock is ridiculousBluetooth auto-unlock is unreliable at bestApp connectivity can be spottyFor the price point, the software experience should be much better. If you're buying multiple locks, be prepared for some tedious setup and management.Pros:Easy installationGood build qualityDecent fingerprint readerCons:Terrible app experienceNo fingerprint sharing between locksUnreliable auto-unlockExpensive for the features you get

Bought this as replacement to an older version Yale assure lock. Old lock worked great in terms of mechanical operation, app functionality, and network connectivity. This version falls extremely short of expectation and as a read around on numerous forums it appears many others experience the same frustration.Installation: physically the lock is a fast an east install. If you're comfortable installing a standard mechanical lock you'll have no problem with this. Even if you're a beginner DIY'er the installations are clear and easy to follow. The inital setup however can be painful. First off, the Yale Access app is horrendous. It's clunky and seems little thought was put into development and testing. Establishing a connection between the lock and app is very flaky and consistently drops out (which seems to be common feedback/frustration from others). I had to reset the unit/app several times just to finally perform the inital setup. Customer support was very unhelpful, basically just read the instructions to me over the phone and offered no real technical troubleshooting beyond what I could already do myself.I also installed the door sense system included with this (identifies when the door is open or closed) with same level of frustration during install.Once installed, app connectivity remained an issue from day one. One selling point was to be able to use the app (or proximity via the app) to unlock versus the keypad. The app rarely connects to the lock and I often need to attempt connection 10-12 times before giving up and using keypad. Proximity unlocking never works because the app won't establish connection. Door sense is extremely temperamental. It often detects the door as closed when it's actually open then attempts to auto-lock (which then results in someone slamming the striker into the jam as it auto locks while you're closing the door). Often when it autolocks, the mechanism will continue actuation which repeatedly moves the striker after being in the locked position which prematurely wears the mechanism (I've ensure there is no interference on the strike plate). I've ready the wifi module os very unstable so I later purchased the zigbee module and linked to my Smart Things hub yet functionally and connection are no more reliable. At this point, I use the keypad to lock/unlock from outside, and manually turn the lock when inside to lock the door basically making all the features I paid for useless.The only positive I see is the touchscreen keypad does seem more durable than the previous version. Old version showed signs of crazing in the plastic (little micocracks from UV exposure) and this 2nd version seems more stable.Yale wants nothing to do with making this right and deny any issues in the hardware and software and state its a network issue on my end. As a side note, my home network has no issue supporting any other device in my home and my poor experience seems to be shared my many other owners of this lock.I do not advise wasting your time or money on this lock.
