Door sensor malfunction

How do I reset, (or delete and then add) door sensor that keeps giving me malfunction alerts? I replaced battery and this sensor is the closet one to the panel.

I don’t think that is likely necessary here.

I do not see any sensors showing a malfunction on your system. I see a Z-wave door lock showing a malfunction and it is labeled the same thing as one of the sensors, which is likely causing confusion. (master bedroom door)

Z-wave malfunctions on a door lock mean that the door lock batteries likely need changed, or its range or lack of repeaters is causing some signaling trouble.

Z-wave is a mesh network which relies on AC powered repeating Z-wave devices like light switches to strengthen the network. Malfunctions can be common if you have 2 or more locks and no repeaters.
