While it is not necessary to calibrate the Kevo fob, it is recommended to do so for enhanced security purposes.The calibration process enables Kevo’s inside-outside security feature. When enabled, Kevo’s sensor helps prevent your door from being unlocked by unauthorized users while your Fob is inside your home.
If the calibration results in a red flashing light ring at the end of the third touch sequence, then a poor calibration was performed. This could be due to where you are carrying your Kevo fob. You can accept a poor calibration, however accepting a poor calibration is not advised and could cause Kevo to be susceptible to unauthorized operation while your Kevo fob is inside of your home. If you continue to have calibration issues, please call Kevo support.
