Noke is a padlock you unlock with your smartphone, eliminating the hassle and frustration of lost keys and forgotten combinations. The device works with iOS, Android, and Windows smartphones that include Bluetooth 4.0.

It’s useful for plenty of applications, from locking your bike to securing a toolbox holding precious and pricy power tools. It’s so easy to use that you won’t need to launch the app or even remove your phone from your pocket. The lock activates when your app-enabled device is within 10 feet. All you have to do is press its shank and you’re good to go. If you ever forget your phone, you can still unlock the Noke with a custom emergency code.  The Padlock is safe to use in all weathers too.

You can easily share access to your Noke with others via the app. It tracks who, when and where the lock was used.
