CentraLite Keypads

Since its a zigbee keypad it may not hurt to perform a zigbee repair:

ZIGBEE HEAL: UNPLUG AND PLAY   

For zigbee, healing the networks occurs automatically whenever the 
hub is powered off for about 15 minutes or more. It may take an hour or 
two before the routing tables rebuild completely, but you don't have to 
do anything other than unplug the hub, wait at least 15 minutes, and 
then plug it back in.
