The #1 issue of smart or dumb locks are the strike plates, not the mechanical construction.
From Consumer Reports:
Many of the deadbolt locks tested by Consumer Reports lack the level of protection you might want or expect. In our labs, a few well-placed kicks or a couple of minutes under assault from a cordless drill was all it took to defeat almost every lock in our ratings. That goes for conventional deadbolts and smart locks—those you can operate with your smartphone.
For the kick-in tests, CR’s test engineers built a custom jig that allows them to swing a 100-pound steel battering ram at a replaceable section of door with the deadbolt installed. They repeat the test eight times, at ever-increasing heights, or until the lock fails. The models that fail—and at least half do—then go through another test round with a reinforced box strike plate installed on a new lock sample.
But the fix is easy:
All locks come with a strike plate that attaches to the door jamb. But as we’ve reported in the past, far too many of those included short screws that catch only the jamb and not the framing of the house. The kick-in resistance of most locks improves dramatically when we replace a stock strike plate with 3-inch screws and a box strike, which you can buy online for as little as $5. “We think manufacturers should include beefier hardware with their locks,” says CR’s lock test engineer, David Trezza. “A lock should be secure without having to buy an aftermarket part.”
