Sentry Safe keypad beeps 5 times and won't unlock. What's going on? 

When the Sentry Safe keypad beeps 5 times after you enter the correct code, this is likely what's happening.
"How can I open this locked safe?"
You can't open the safe even with the code. Something has gone bad inside the safe.
The only solution is to physically destroy the safe, in this case.
I tried the magnet. I called Sentry Safe and followed their instructions. I tried lightly tapping on the safe with a hammer.
When the electronics on the solenoid fail, you are stuck.
