Sentry 2210 vs. 2920 safes

[VVG]

I have to manuever a safe into an out-of-the way place so these models seem to work around 200 lbs so they can be man-handled in. The 2210 has three bolts , a thicker door, and a key lock. The 2920 has five bolts and a combination lock. Are those significant advantages?

A key can be easily lost and/or used by someone else.........combo lock is known only(??) by you--write it down and put away in safe-deposit box just in case!!

I'm curious if anyone has ever had their safe broken in to. I talked to a LEO, he knew of one case in nearly twenty years, and it was an inside job at a dealer.
