Virtual Keys of August Smart Lock Pro 3rd Gen

If you have a large family or you are having too many visitors you might be asking yourself “How i will let my guests in even if i am not near the house?” The answer is very simple. You can create 3 types of virtual keys with August lock app.

  • Always: This type of key gives the user full time access without any day or time limitations.
  • Recurring: This type of key is very useful if there will be visitors at the same day and hours every week repatedly. As an example if you are having a service in your house which is always at Wednesday between 10:00 AM and 2:00 PM you can let your guest in at every Wednesday between 10:00 AM and 02:00 PM .
  • Temporary: This type of key is very ideal if you want to define specific date and time range which will not repeat every week and expire after ending date and time. As an example a house owner can use this key to let AirBnb guest in the specified date and time range. Owner can create this key for customer A as valid through 01.22.20 – 01.24.20 between 09:00 AM to 03:00 PM. It will not work after 03:00 PM 01.24.20.

Battery Life of August Smart Lock Pro 3rd Gen

Battery life at smart locks generally differ by many factors such as usage frequency, lock’s turn number, condition of the door, weather, etc. August Smart Lock Pro 3rd Gen is powered by 4 x AA batteries which means you have to always change your batteries continuously if you don’t prefer rechargable batteries. You should always open the lock and take out batteries which is not practical in our opinion but don’t worry it is not difficuly to change them. If there were a charging port like micro usb which can charge batteries without taking them out it would be much better.

August Smart Lock Pro 3rd Gen does have a low battery warning system which comes to you as a notification over app while your battery level is at 20%. Additionally, light on the August Smart Lock Pro 3rd Gen flashes red when the batteries are at %20 or lower. You can expect to change batteries at every 1 – 1,5 months for 6-10 times daily usage. It is advertised as 6 months as bettery life but in practical life this is not real unfortunately. Even if you don’t change your batteries in the needed time you can still use your key to unlock the door.

August Smart Keypad

August Smart Keypad is a controller which is sold separately. Keypad entrance is widely used so most of the people prefer this option. This keypad is extremely easy to use. You can create any kind of user codes for your needs. As an example we can say you can give access to your guests, your baby sitter,house cleaner, contractor to enter your house in the defined time range. You can set all of these from August lock app.

If you want to track who/when has entered to your house over the app then you should enable Homekit. August Smart Keypad has also one button locking option. August Keypad one touch lock makes locking as simple as pressing the red August logo at the bottom of the keypad. Keypad uses Bluetooth connection.

Keypad has backlights but you should first touch one of the buttons in order to activate. This can cause wrong code entrance some times as you might miss the first correct number of your keypad while you are in the dark but buttons are large and well designed so this not likely to happen usually.

August Smart Keypad has also motion sensor but it can be activated only with August Doorbell Cam Pro . Battery life of the product is not very good. Avarage battery life could be expected as 1,5 months with 5-6 times daily usage but this could change depending on the temperature where device is used and quality of the batteries. It has also low battery warning system over the app and via e-mail. Sizes are pretty small as 1 x 2.9 x 0.9 inches.
