test program at Consumer Reports. In our lab tests, Door Lock
models like the Real Living YRD226-ZW-619 are rated on multiple criteria, such as those listed below.
Kick-in as sold: Resistance to kick-in as sold is how well the lock survived increasingly forceful impacts using the hardware it comes with.
Kick-in reinforced: Kick-in reinforced is the same test using an aftermarket Box Strike in place of the included strike or, for surface-mount locks, 3-inch screws; models scoring Excellent as sold were not retested.
