Just wanted to give a heads up to other gun vault owners.
I bought it about a year ago and have been very pleased with it. It's secured to the night stand on my wifes side (mine is holstered on the other side)
The other day I went to open it to change the moisture pack and give her S&W a quick wipe down. I put the code in and heard a small "click", but the spring loaded door didn't open. Tried again, same thing. Luckily this wasn't a life or death situation. I keep the key for it near by, but if my wife was alone and had to open it quickly those few extra seconds to get the key could have made a big difference.
The problem was low batteries. It was about a week since I last opened it and the batteries got low enough during the week to not have enough power to unlatch the door. There wasn't a low battery indication.
So now I'm trying to get into the habit of checking it every morning and evening.
Just though I'd give other Gun Vault owners a heads up.
