Here's the good news: If you've been thinking of buying an August ASL-02 smart lock but find the price too steep, the Danalock BT100BC has almost exactly the same features and costs substantially less. It even has the stylish looks of the August lock. And it lets you unlock the door remotely, a feature that costs extra with the August lock. The bad news it that a lot of users, including CNET's reviewer, say that it doesn't work as well as the August lock. So the old saying is true: You get what you pay for.
The Danalock is supposed to give you Bluetooth control over the lock on your front door. That means that if it senses your iPhone in your pocket with the Danalock app running in the background, it should open automatically. No more lugging keys around -- if it works. You can also use the app to open the lock remotely, in case one of your kids left their smartphone at school, though you need the Vera Gateway Z-Wave smart home controller for that feature to work. It does have an advantage over the August lock. While that lock limits you to 120 electronic "keys," so that you can grant access to multiple users, the Danalock allows an infinite number of keys. However, this is only useful if you're using it on a fairly large apartment building. It's difficult to see how a single homeowner could possibly need to hand out keys to more than 120 people.
Like the August lock, the Danalock isn't a complete replacement for your existing lock. It screws on top of it, using the existing deadbolt and allowing access with your old key if the Bluetooth doesn't work. But this is another area where reviewers say it comes up short. It only fits over certain shapes of lock, requires a special tool (not included) to screw in, and is still a bit wobbly even if you have the right shape of lock and the right tool. So you should give serious thought to getting the August lock instead.
And if you want a complete replacement for your existing lock, you'd be better off with the Kwikset Kevo, which also unlocks when it senses your iPhone's presence.
Incredibly poor instructions for both installation and setup.
It kept forgetting my key when I was away from home, so when I got home it wouldn't automatically unlock as expected.
