Most break-ins are committed by criminals who come right through the front door, according to Department of Justice statistics. Even if you’re diligent about locking up, you need a good deadbolt to thwart thieves.

That's why CR engineers conduct kick-in tests using a custom-built jig that swings a 100-pound steel battering ram against a locked door. They repeat the test eight times, with the ram raised to ever-increasing heights—or until the lock fails.

"In our brute force kick tests, the cause of failure is more often than not the short screws used to attach the strike plate to the door frame," says Misha Kollontai, CR's test engineer for door locks. "When this is the cause, replacing the included strike plate with a reinforced strike, which costs as little as $10, improves the locks' resistance to kicking by magnitudes."

After putting dozens of locks to the test, we’ve selected five of the best from our door lock ratings. The list includes models from August, Medeco, Schlage, and Yale. We’ve also included four models to skip. These performed poorly in our physical challenges and/or our tests specific to smart locks. CR members can click on each model name for detailed ratings and reviews.

Best Standard Door Lock
Yale Premier Single Cylinder YH82
Yale Premier Single Cylinder YH82

    Yale Premier Single Cylinder YH82

    CR's take: The Yale Premier Single Cylinder YH82 is one of the strongest conventional deadbolts you can buy. It stands up well to kick-ins as sold and receives a Good rating for drilling, which is the highest score of any standard deadbolt in our ratings. Other locks are better-designed to resist picking, though. This Yale lock also comes with a lifetime warranty on its internal mechanism and its finish.

    Best High-Security Door Lock
    Medeco Maxum 11*603
    Medeco Maxum 11*603

      Medeco Maxum 11*603

      CR’s take: The Medeco Maxum 11*603 is the strongest deadbolt across all of our lock categories. It rates Excellent for drilling (it's the only lock to do so), withstands kick-ins very well, and is designed in a way that makes it very difficult to pick. This Medeco also comes with a lifetime warranty on its internal mechanism and its finish.

      Best Electronic Door Lock
      Schlage Touch Keyless FE375 CAM
      Schlage Touch Keyless FE375 CAM

        Schlage Touch Keyless FE375 CAM

        CR's take: If you want a door lock with a keypad but don't want it to connect to the internet or your smartphone, consider this Schlage Touch Keyless FE375 CAM electronic deadbolt. It receives an Excellent rating for its resistance to picking, and proves difficult to drill and kick-in. This Schlage comes with a 25-year warranty on its internal mechanism and a five-year warranty on its finish.

        Best Smart Lock
        Yale Assure YRD256-CBA-619
        Yale Assure YRD256-CBA-619

          Yale Assure YRD256-CBA-619

          CR's take: The Yale Assure Lock SL uses its sister company August's smart lock app and platform. That means it offers many of the same features as the August smart locks below, including remote control, an access log, voice control (via Amazon Alexa, Apple HomeKit/Siri, and Google Assistant), electronic keys, and a door open/close sensor. In our tests, the Yale receives a Very Good rating for its resistance to drilling. It's also impossible to pick, because it's keyless, and it's very resistant to kick-ins as sold.

          Best Retrofit Smart Lock
          August Smart Lock Pro AUG-SL-CON
          August Smart Lock Pro AUG-SL-CON

            August Smart Lock Pro AUG-SL-CON

            CR's take: The August Smart Lock Pro offers compatibility with Apple HomeKit/Siri and Z-Wave Plus smart home hubs. It rates Excellent for convenience in our tests, and it's very easy to set up. Just note, you'll need the August Connect WiFi adapter, $79, to get access to all of the lock's features.

            Worst Door Locks
            LockState LS-DB500R-SN
            LockState LS-DB500R-SN

            LockState LS-DB500R-SN

            CR's take: The LockState LS electronic lock is highly susceptible to drilling, picking, and kick-ins as sold. This lock simply won't do much to protect your front door.

            MiLocks DKK-02SN
            MiLocks DKK-02SN

            MiLocks DKK-02SN

            CR's take: The MiLocks DKK-02SN electronic lock stands up to drilling fairly well, but that's about all this lock can do. It's susceptible to picking and doesn't stand up well to kick-ins even when reinforced with a box strike plate.

            MiLocks ZWF-02BN
            MiLocks ZWF-02BN

            MiLocks ZWF-02BN

            CR's take: The MiLocks ZWF-02BN smart lock is very easy to drill, pick, and kick-in (even when reinforced). There are stronger, more feature-rich smart locks worth considering.

            Weslock 671
            Weslock 671

            Weslock 671

            CR’s take: The Weslock 671 is a weak deadbolt that can’t stand up to drilling, picking, and kick-ins as sold. There are better options for the money.
