Your smartphone is the key to your padlock – no more forgotten combos!

Enjoy speed & ease of use, share access, have greater control with temporary keys/codes, tamper alerts, low battery notifications and a history log. With a Bluetooth Smart-enabled device, you and your guests can unlock & lock your Master Lock Bluetooth Smart-enabled padlock using digital, encrypted “keys”. If you don’t have your phone with you, or you need to share temporary access with someone, the lock can be opened using an up/down/left/right directional code entered on the lock keypad. In default Touch Mode, the lock unlocks upon pressing any button on the lock when your phone is with you. In optional Swipe Mode, the lock can be unlocked with a swipe in the app. The lock owner can easily add and remove guests and schedule guest access to 24/7 or limit to days or nights. Locker Mode allows for maintaining a locked state while the phone is stored inside of a locker. The lock history log captures lock registration; unlock, open and relock activity; unlock method (via Bluetooth Smart-enabled device or directional code); date, time and user (if known); guest invitations, acceptances, access revocations; lock keypad tamper alerts; low battery alerts; Primary Code changes; settings changes (Automatic Relock Time, Locker Mode, Unlock Mode, Time Zone); reset keys activity and firmware updates. The lock batteries are replaceable and can be jumped with an external battery if the battery dies in the locked position. Two models are uniquely designed for either indoor or outdoor lock applications, with special fitment and environmental considerations. The outdoor model features a full 2-piece injection molded body cover and shackle seals for added resistance to weather and dry contaminants.

It Works. But It’s Annoying and Wonky.


The app definitely works with the lock box to open and close it. But the app interface is annoying. Every time you do anything - add a guest, unlock the box, have the guest accept the invitation - you get THREE separate texts. The first one tells you there’s activity. The second tells you what the activity was. The third tells you to manage your notifications in the app. EVERY SINGLE TIME. When you attempt to reduce your notifications to the bare bones, you still get three texts with every single action. Also, the invitation to a guest is only good for a week. If they don’t accept it, you have to invite them again. But the app doesn’t like that. It keeps telling you the phone number has the wrong number of digits. There isn’t a way to delete the guest and start over. So user-intensive and annoying. MasterLock, take a look at the sleek and intuitive August app and move into the 21st century. If my doors would accept the August lock I would use it. But I’m stuck with this clunky old thing.

Have two devices with your lock (just in case lol)


Sometimes it well for a while the it has to be recalibrated or delet install app. I have it on my iPhone and iPad so when one doesn’t work I use the other but it’s better than worry about keys. The lock itself it’s nearly perfect hasn’t gave me one single problem band the app is making significant improvements!

This smart lock is as dumb as they come. What’s the point of a smart lock that requires you to dig out your phone, unlock it, AND open the Master Lock app in order to unlock it? It’s far easier and quicker to use the back up combination. Should have saved $$$ and bought a standard combination lock.

Listen up Master Lock, as long as the app is “running,” the lock should unlock when the button is pushed and the phone is locked but within range. That’s how many apps work, such as Tile and Sweatcoin. I’m going to pick up a Nokē and see if it’s software is any better.
