My new U-Bolt Pro WIFI lock rips through batteries in less than two weeks! I do not have Auto Unlock enabled which I understand causes fast use of the battery. The lock works very smoothly; it is not binding at all. The lock is being used in a group home of ~ 8 people so a lot of people are coming and going so I’m sure that has some influence but less than 2 weeks? What is pulling down the batteries? I am using EverReady Max alkaline batteries. Help!
