Does yours use AA or 9v? I have the old AA version, and I go through batteries every two months....and the second month I have to enter the code twice to open it. At the Houston NRA Meeting, I talked to a GV rep about the problem. He said they knew about it& changed the design to a 9v system. When I asked if the older models could be retrofitted, he said they weren't designing a fix. His advice: "Buy rechargeable batteries."
I haven't bought a GunVault product since.
