About

The Emtek 8455 is part of the Door Lock test program at Consumer Reports. In our lab tests, Door Lock models like the 8455 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.

Drilling: Drilling shows how well the lock stood up to assaults with a drill.
