Thanks, all, for your comments!
I'm going to work on the circuit board, which is tiny, today...as you all note, I have nothing to lose now!
If I can get it open, I can get the lock changed out pretty easily (at least, that's what my safe expert in Oklahoma told me).
RE: CANNON...if you have a "Lifetime Warranty," that means it's you warranty the product for the lifetime of the original owner. If you have a "Lifetime Warranty*" followed by 10 pages of weasel words, you don't have a lifetime warranty at all...you are, rather, a liar.
If you guarantee consumer satisfaction, and you treat said consumer — any consumer — like crap, you are worse than a liar...you are attempting to perpetuate a fraud.
The company shouldn't take notice of whether it's me or you or anyone when it comes to standing by its products. A quality company — Midway, Dillon, Ruger, Para, RCBS, etc. — doesn't care who the customer is, because all customers are treated the same...pretty much like royalty.
If your customer service rep — supposedly one of the best in the business, according to your advertising — actually threatens a customer about saying "bad things" about the company in question, it raises a red flag to me. Something is wrong with that company or that customer service rep would never in a million years think to threaten a customer.
If Cannon stands up, I'll give you chapter and verse and happily apologize to the president of the company. If they don't stand up, I'll video me buying a new safe at SHOT!
And I will NOT ever own another electronic lock!!!!!
