Master Lock 4400D Indoor Bluetooth Smart Padlock

This is a basic Bluetooth lock, but it comes from a reliable brand. Designed primarily for indoor use, this lock works with your phone and lets you quickly open a locker, safe, or lockbox with a quick touch. If you leave your phone in your locker, you can use a directional code on the padlock to open it.

With a durable, 47mm wide metal body and a 7mm (diameter) shackle, you shouldn’t have to worry about breaches. The Master Lock 4400D comes with a CR2450 battery you can jump-start in the event that it dies while locked. You also use the mobile app to share access to your lock and monitor access.

Boread Fingerprint Padlock

For those looking for a low-profile smart lock for their luggage, the Boread Fingerprint Padlock measures a little over half an inch thick. This smart padlock can store up to 20 fingerprints, including two administrator fingerprints. It’s possible to unlock the Boread Fingerprint Padlock without needing an app, key, or Bluetooth connectivity.

The 100mAh battery can last up to a year on standby. Use a Micro USB cable to recharge it when needed, making it last about another 2,500 uses. The zinc alloy body provides a standard level of durability, but don’t count on using it outdoors like some of our other picks here.

Lametuty Fingerprint Padlock

The Lametuty Fingerprint Padlock is all business. The 0.49-inch-thick shackle is made of stainless steel to hold up to would-be intruders. The 4-inch zinc alloy body is built to resist brute force, while the IP65 weatherproofing ensures it can last under rain and dust, too.

A mobile app is available to authorize up to 13 fingerprints, plus set two administrators. The app also allows you to review activities and see who has used the smart padlock. After six months of standby or 2,000 unlocks, you can charge the lock over USB.

Master Lock Lock Box

Have you ever seen one of those lockboxes on the front door of a home you’re about to tour? Your realtor opens the box to find a key inside. This product by Master Lock is a similar idea, as it holds a cavity inside for keys, key cards, or even small trinkets.

Designed for indoor and outdoor use, you can access this weather-resistant lockbox via Bluetooth and your smartphone. There’s also a keypad on the Master Lock Lock Box for backup access. Once you open the lock, you can access the internal key, making it an excellent option for Airbnb hosts.

BoxLock Package Delivery Lock
