Ok, here's the situation. I went out of town and I took my keys to my gun cabinet with me, instead of keeping them locked inside my pistol safe like I usually did. I figured since I would be gone for a good amount of time, I didn't want the keys being left in the apartment. But now, I've either misplaced the keys or they are just gone forever. Whatever the case is, I cannot find them to save my life. My gun cabinet is a sentry, the cheaper thin walled type. Just like the cheap stack-on ones you can get. It has the tubular key lock. Aside from destroying the cabinet by cutting it open, what else can I do? Can a locksmith open this type of lock? And even if they can, how on earth can I get new keys for it? I don't even know where the paper went that had my key code on it. I have a feeling i'm SOL either way. If I can't get new keys for it, then it's useless and I'd just waste money having a locksmith open it for me. I'd be better off to just destroy it to open it and purchase a new one.. that's assuming I can't get keys for it and I never find my keys.
