Schlage encode stopped working, guest locked out temporarily

[James Nelson]

I have 2 Schlage encode locks at my beach house and they both simultaneously crapped out within a few hours of each other. I think it was due to either getting wet or condensation because there was water in them when I opened them up. I have a manual lockbox but I forgot to put the new key in there after switching the locks out. I live an hour and a half away so I had to drive and unlock the door for the guest. They were locked out for about an hour and a half and they had an infant with them. What kind of compensation would you offer the guest, if any, and are there any better locks out there for hot, humid weather conditions that are rain resistant?
