Think about how many locks left in your garage but you just can not find their keys. Or your bike got stolen by someone cutting off your cable lock. So here comes Nulock: a smart bluetooth keyless alarmed lock. Our engineers took more than 1 year to develop and test this product. As a smart lock, the following features were tested and approved besides its robust construction: 1. It "knows" you. When your cellphone is close in its bluetooth range, you can unlock it by pressing the unlock button. 2. It "reminds" you about the battery level. 3 AAA batteries last around 8 months. The app always shows the battery power level and warns you low battery with alternating red and blue lights on the lock when power is less than 20% off left. 3. It "deters" destroyer. If your cellphone is not close by, it will make a 110db alarm if any stranger try to break, disassemble the unit, remove battery or clip the cable. You have to use the app with bluetooth turned on to clear the alarm.
