Get a redundant lock.....'nuff said.
Funny the gripes on electronic locks. Really all the electronic locks that come on residential "safes" are very low end. Depending on what brand, both mechanical and electronic, warranties range from 1yr-2yrs.
Although I'm not in CO anymore, I can drop ship almost any lock to you guys. Problem is you'll have to install it or hire a locksmith. It really isn't that hard!!
