What this lock handles at your entry

Before bringing it home
  • Works as a standard deadbolt with passcodes and mechanical keys if the network drops.
  • Fits left-handed and right-handed doors from 1-3/8 to 1-3/4 inches thick.
  • Create up to 50 custom passcodes with one-time or scheduled access for guests, cleaners, or renters.
  • Lockout Mode disables electronic unlocking, such as passcodes and app unlock, while you travel.
  • Comes with batteries, so no separate trip is needed before setup.

This is a smart deadbolt for the door your household uses every day. You can open it with a passcode, the app, an eKey you share, the included mechanical keys, or voice control through Alexa, Google Assistant, SmartThings, and IFTTT. Auto unlock works as you approach with your phone, and auto lock closes up behind you when the door shuts.

The included door sensor is what makes that automation useful. It reports whether the door is open or closed and sends an alert if someone leaves it ajar, which matters most for a side entrance, a rental, or a home with pets that learn doorknobs.

We'd skip the Wi-Fi model only if you won't use remote access. The built-in Wi-Fi removes the need for a separate bridge, but it operates on 2.4 GHz networks, and the manufacturer suggests placing your router within 70 ft of the lock for the best connection. If your entry is far from the router, that distance is the first thing to check before ordering.

The price and what the comparison means

The lock is $84.99, which is $15.41 below the typical price over the last 90 days and about 15 percent off. That's also the lowest price we've seen, based on all-time pricing data. The rating sits at 4.3 from 2,384 reviews, so it's a widely rated model rather than an unproven newcomer.

For a deadbolt with built-in Wi-Fi and a door sensor, that's a fair ask. Comparable locks often push you toward a separate hub to get remote access, and this one doesn't require a bridge.

Fitting it to your door and keeping it running

Installation uses a screwdriver and existing deadbolt holes on most standard US doors. Ultraloq's own tip is not to overtighten the screws, since that can make locking and unlocking stiff. If you rent and can't drill or replace a deadbolt, this isn't the right product for you.

Power comes from standard 1.5V AA alkaline batteries, which the manufacturer says can last up to 8 months with monitoring that warns you before they run low. Keep a spare set on hand, since a deadbolt with no battery means using the mechanical key to get in.

The IP65-rated housing is built for outdoor exposure to rain, dust, heat, and cold, and it's rated ANSI/BHMA Grade 1 for residential security. Coverage includes lifetime mechanical protection and 18 months on the electronics.

When a different lock makes more sense

Avoid this if your Wi-Fi network doesn't broadcast a 2.4 GHz band, because the lock needs one. It's also the wrong pick if you want a lock that works entirely offline with no app or cloud account, or if you need a model for a nonstandard door outside the 1-3/8 to 1-3/4 inch thickness range.

Before you buy, confirm your door thickness and that your deadbolt bore matches a standard US setup. Those two checks tell you whether this is a screwdriver job or the wrong door entirely.
