Why a fingerprint
The weak part of a small padlock is usually the key.
Little padlocks do little jobs: the gym locker, the toolbox, the bike outside the coffee shop, the shed at the back of the yard. The lock itself is rarely what goes wrong. What goes wrong is the key that’s on the wrong ring, or the spare that went through the wash, or the combination nobody wrote down.
So people stop locking things. The locker gets left open "just for an hour". The shed hasp holds a padlock that’s been hanging open since spring because the key is somewhere in a drawer. A lock that’s a hassle to open turns into a lock that never gets closed.
A fingerprint padlock removes the hassle. The thing that opens it is on your hand, so it’s there every time you are. That makes it easy to lock up for five minutes as well as five weeks. The trade is a battery, and the red low-battery light keeps that trade simple: when it flashes, plug in the USB-C cable.
A lock you can open in a second is a lock that actually gets closed.
One finger opens it wherever you put it.
At the gym or at school, it’s a locker lock you can open with wet hair and a towel over your shoulder, without hunting for a key in a bag that’s inside the locker. On a suitcase or backpack, it closes the zips and opens with the same touch.
At home, it moves to the cabinet, the bike or the shed. It’s the same lock and the same fingerprint wherever it goes, and charging it is the same USB-C as a lot of what’s already on your desk. When the red light flashes, give it a charge and it’s good for months again.
Setup is one charge and one fingerprint
Charge it first
Plug a USB-C cable into the padlock and give the built-in battery a full charge before the first use.
Register your fingerprint
Follow the enrollment steps in the instructions to save your fingerprint to the lock.
Test it open
Before you close it on anything, touch the sensor a few times and check it unlocks for you every time.
Lock up
Close the shackle through the locker, zip, bike or hasp. Touch the sensor whenever you want it open.
Anywhere a small key keeps going missing
If you’ve ever stood at a locker patting your pockets, or left the shed unlocked because the padlock key was somewhere in the house, this is the swap. It’s $34.99, it needs no tools, and it charges on USB-C. If it doesn’t do what you just read, send it back inside 30 days. Shipping to the US, Canada, the UK, Australia and New Zealand is free, and most orders arrive 1 to 3 weeks after ordering.
The padlock covers the small stuff. The alarm covers the house.
A padlock keeps a locker, a bike or a shed hasp closed, but the doors and windows of the house need something that reacts when they’re forced. A TremShield Alarm sticks to the glass or the door, no Wi-Fi and no subscription, and fires a 125dB siren the moment someone forces it. One alarm is $29.99; six are $99, which is $16.50 per alarm (Save $80.94).
