Your Baldwin® Evolved lock has a unique inside-outside sensor to detect if the authorized user is inside or outside of the house. Performing the calibration process on your fob will enable this feature and fine tune Kevō 's sensors, minimizing the potential for accidental unlocking from outside by an unauthorized user. Certain home configurations may impede the lock’s sensor more than others. For example: Your home office is located next to your entryway, and part of the office extends past the front door, jutting into the front yard. If your Kevō fob is being actively used in that office extension, the Kevō lock’s sensor could possibly detect the Kevō fob as being outside of your home while that Kevō fob is in active use.
