Had a problem with my Sentry fire safe - first the keypad door release failed to work, then the backup key wouldn't get into it. I called three other lock/safe companies, got a consistent story: they'd have to "drill it" (open by force), thereby ruining it and costing me somewhere between $75 and $150 for the privilege. Harbison not only got into it, they had it fixed in 24 hours - now both the keypad and key work, and for $60 plus the cost of the 4 AA batteries it needed! Pure heroism - I drove away singing.
The tech gave me a wonderful tip too: "change the batteries out every time the clocks change for daylight savings time". That's a great reminder for a lot of seasonal jobs (smoke alarm batteries, cleaning gutters, etc) around the house. His "tip o' the day" alone was worth the whole hassle with the safe.
