While you can technically use the lock without this third hole, it’s clearly there for a reason: To add stability to the lock and to keep it from listing one way or another. Through this hole a third screw connects the two escutcheons. Much like its predecessors, the Igloohome Deadbolt S2 still requires a second hole drilled into your door, a few inches above the primary one. Unfortunately, the streamlined design and the new sensor makes getting all of this put together a bit of a bear. If the batteries in the Igloohome Smart Deadbolt 2S die, and you don’t have 9-volt battery available to jumpstart the lock, you can use a four-sided physical key to open it. It’s also worth noting that the keys included are copy-resistant, with cuts built into four faces. This is hidden underneath a little magnetic coin on the front face, and it gives you a helpful backup-in addition to the 9-volt battery terminal underneath the lock-in case you need to get in without a PIN or your phone. Igloohome still offers an integrated physical keyhole built into the lock. This serves to detract from the otherwise clean appearance of the device. While this is a nifty idea (as many locks can’t tell whether the door is open), it unfortunately means you must place the sensors right next to the handle, rather than in a less conspicuous location. The magnetic portion attaches to the door frame opposite the lock. The sensor works like a traditional magnetic security sensor, with a powered component (which draws power from the four AA batteries that also power the lock) physically attached to the interior of the lock. The new integrated door sensor adds utility (the lock knows whether the door is open or closed), but the feature also adds to the complexity of the installation while detracting from the lock’s otherwise svelte appearance.ĭespite its diet, Igloohome has added numerous new features to the lock, the most visible of which is an integrated door sensor that’s built into the lock.

(The interior body is also much slimmer, dropping from 50mm to 30mm thick.) As smart locks go, the slick, jet black hardware looks great, successfully avoiding the overly industrial look common in this space. Igloohome has streamlined its hardware, trimming the thickness of the numeric touchpad-featuring outer body (the part that is exposed on the exterior of the door) from 30mm to a mere 11mm. Let’s start with the physical presentation of the lock.
