By activating the Hold-back-Latch feature, Danalock retains latches in your door. You can configure it to hold the latch for up to 15 seconds. This feature must be enabled if you do not have a handle outside the door. You enable this feature in the Danalock application. If you have the version of Danalock V3 Homekit, you activate this feature with 4 clicks with a paper clip on the top of the lock in a small hole. Choose from five to 15 seconds. Download the click commands for Homekit here.
