All-Weather Protection: Smart Lock is built tough with an IP65 weatherproof rating designed to withstand prolonged rainfall as well as temperature swings from -22°F/-30°C to 158°F/70°C.
Easy to Install: Install the deadbolt lock in just 15 minutes, all by yourself, using only a simple tool–saving you from calling a contractor.
Long-Lasting Charge: The 10,000 mAh lithium battery allows you to enjoy convenient unlocking without constant recharging. To charge, simply remove the battery or power up directly via the micro-USB port.
Notes:
• The elderly and young children should use the keypad or their keys to unlock Smart Lock due to changes that happen to our fingerprints during these life stages.
• Check the edge of the latch hole before installation. If your door doesn’t have a rectangular cutout around the latch hole, you can use a flathead screwdriver to pop the rectangular faceplate off. Afterward, attach a round drive-in faceplate by sliding it over the top of the bolt and snapping it into place (round drive-in faceplate is not included, but you can contact our friendly support team to receive a kit).
*The Google Assistant and Alexa are not built into Smart Lock Touch & Wi-Fi.
What’s Included: Exterior assembly, interior assembly, deadbolt, strike plate, strike reinforcer, screw pack, rechargeable 10,000 mAh lithium battery microUSB charging cable, user manual, and a welcome card.
