I have had the misfortune of owning 2 Sentry safes, both purchased from Costco (thank goodness). After the first safe was beyond the 1 year warranty, it stuck shut.
I called Sentry, did everything they said and could not open it. They did send me replacement parts, to no avail. Fortunately, I accidentally mentioned this to Costco, they not only replaced the safe but also paid for a locksmith to come out and open it. They wound up having to hammer it out, breaking the lock.
Got a new safe from Costco, after 3 years, this safe is now stuck open. I have called Sentry Safe numerous times, while they have tried to help, nothing worked. I now have a locksmith out attempting to fix it to no avail. Who ever expects a safe to totally fail this early in its life?
By the way, this was a top of the line safe. Never, ever, ever will I own another Sentry product.
Monetary Loss: $800.
