Aegis SmartLock Pro
A Matter-native deadbolt that finally gets the basics right — fast, reliable, and a year between battery swaps. We lived with it for six weeks.

The verdict
The Aegis SmartLock Pro is the rare smart lock that disappears into your routine — it unlocks when it should, lasts a year on a set of batteries, and speaks every smart-home language. At $229 it isn’t cheap, but it’s the one we’d put on our own front door.
What we liked
- Rock-solid Matter support — pairs with Apple Home, Alexa and Google
- Roughly a year on four AA batteries in our test window
- Auto-unlock fires before you reach the door, not after
What we didn’t
- The retrofit kit costs extra for thicker doors
- The app is functional but looks a generation old
Smart locks have spent years over-promising. The Aegis SmartLock Pro is the first one in a while that just works — quietly, reliably, every single day.
Installation
If you can hold a screwdriver, you can fit it. The Aegis replaces the interior side of a standard deadbolt and leaves your exterior key cylinder intact, so you keep a physical fallback. Our install took about twenty minutes. The one catch: doors thicker than 1¾ inches need an add-on spacer kit that Aegis sells separately — worth checking before you buy.
Living with it
This is where it earns the score. Auto-unlock uses your phone’s location and a short-range check, so the bolt is already turning as you walk up — no awkward pause on the porch. Over six weeks it never once failed to re-lock on its timer, and the keypad meant guests never needed the app at all.
Battery and connectivity
Aegis rates the battery at a year; our test tracked toward that comfortably. Matter support is the real headline — it dropped into Apple Home and Alexa without drama, and stayed connected. If your home is a mix of ecosystems, this is the lock that won’t pick a side.
Where it falls short
The companion app is dated and a little clunky, though you rarely need it. And the extra cost for thicker-door hardware is an annoyance at this price. Neither dents the fundamentals: this is a lock you stop thinking about, which is exactly the point.
