The Yale Real Living Assure Lock is the third lock in Yale's Real Living series and it's the first that doesn't require either Apple Homekit or a Z-Wave whole home system to operate. Just pair up to five phones with it via Bluetooth and you're good to go. (You can even pair it with a Samsung Gear smart watch.) To unlock it, just rotate your smartphone or watch in front of it and tap in the PIN code that you've set up using Yale's app. You can create PIN codes as needed so that friends, workers or pet sitters can get into your home and then delete them at will when they're no longer needed (or when the pet sitter starts renting movies on your smart TV and charging them to your account).
The unit is totally keyless, which on the plus side means that nobody can pick the lock to open the door and on the negative side means that you'll need to keep the 9-volt battery charged so that you don't get locked out yourself. (In a pinch you can attach a battery externally to reactivate a dead lock, so you might want to keep one securely hidden somewhere in the shrubbery.) The door locks automatically on closing, but this feature can be turned off and back on if party-goers or workers want to wander in and out without having to ring the doorbell every time they want to get back inside. And if you really want it to work with a whole home system, it can be upgraded to work with Z-Wave and Zigbee devices.
The Connecticut-based Yale has been making combination locks since the 1840s, so it's probably safe to assume that the purely mechanical aspects of this lock are up to snuff. Some Amazon users complain that Yale's app (which probably hasn't been available since the 1840s) is sluggish and moves slowly from screen to screen, which might explain why this unit only gets a 3-1/2 star rating with Amazon users. For other smart locks, look at the Adel Keyless Biometric, the August ASL-02 and the Schlage Connect.
I had no trouble with installation and setup and have been using the lock on a daily basis for over a month now and have had zero issues.
The lock seems to be okey so far. The app on the other hand is horrendous. It is too slow to even think about using.
Yale Assure is a quality smart lock with a nice design and is easy to install and use. It's a great addition to any Z-wave smart home system.
