Bluetooth technology allows you to unlock a padlock from afar

Keyless wonder: Dog and Bone's Bluetooth padlock allows users to open the lock with their smartphone from either the Android or iOS app.

Dog and Bone has introduced a keyless Bluetooth padlock, which is controlled by a free iOS or Android app.

I can't say it is or isn't the first; I can say I've never seen one before and this one works great.

The main feature is the Bluetooth and with that, you won't have to clog your brain with another code to remember or look for a key. Instead, just call up the app on your smartphone and open the lock. It's really that simple.

The lock a really durable and rugged look and design is made from hardened steel, die-cast Zamak-3 Zinc Alloy.

There are rubber bumper guards on both sides of the lock and a rubber door to hide the USB port.

All this gives it full weatherproof protection from rain or snow and all-day sunshine won't harm it.

The lock has been tested and rated to work in temperatures ranging from minus 20 to 70° F.

Inside is a lithium-ion battery, which is charged via microUSB to give users up to two years of power or "as many as 3,000 unlocks before a recharge" according to the company site.

I used it for a few days, locking and unlocking a few dozen times or so, all with perfection.

Within the app, you can choose to have the lock unlocked with a single tap, your thumbprint or a four digit code. I used all three but eventually stayed with the thumbprint.

The app can also manage multiple locks and let you know how much power is left before a charge is needed.

It also runs a log of the locks activity to display username, date, and time of use,

According to the company, LockSmart offers the highest Bluetooth security standard with 128-bit advanced encryption.

Sharing access to your keyless Bluetooth lock is simple, just press a button within the app and they get access sent to their smartphone to open the lock.

This makes it great when workers arrive before you get home and they need access to a gate or shed.  Once the lock is opened you can remove them from the access.

The device costs US$89.95 (RM386.50). More info at www.dogandbonecases.com . — Tribune News Service
