I have The Protector model safe by Sisco, bought maybe 13-14 yrs ago, now discontinued. Cannot open it, I have the combination, that’s not the problem. No key option. At times I can’t even turn the dial but If I pound around the dial, it w/ free up. I’ve tried everything, rocking it in case something is wedged up against the door, #’s one or two off, pushing against the door, holding the handle w/ a little pressure while dialing, etc., nothing. Guess I’ll have to call someone. I read where if you have a lock problem, call a locksmith, if you have a safe problem, call a safe guy. Obviously I’d prefer that it needn’t be drilled/ruined despite it not being a real expensive safe, but it has to be opened. If I have to replace it then so be it. Any recommendations? Thank you in advance. What a PITA!
