My cannon acts similar or the same often. Electronic lock seems to be working fine but it seems like the internal unlocking/locking mechanism isn't engaging properly when I spin the handle. The handle will be just free spin. I've been locked out of it several times due to this. Eventually I figured out it would engage more consistently with a softer touch or easing into the spin to unlock. I have a good friend who has the same or very similar cannon and it has the exact same issue as mine.

BTW- mine is the cheapo depo version sold at the box stores. Got mine at Tractor Supply and wouldn't buy another in the future. I do have another cannon that I bought direct from them nearly 20 years ago. It's quite a bit smaller but cost me 3x the money back then than this problem safe did. I've never had an issue with it but it's locking system is different, appears and functions like it is of much higher quality.
