I hope so but in the meantime, I tried with other cards - 4 different SD cards, both Lexar and Sandisk - and they all end up with the same answer.

The "lock" tab on the card is just a piece of plastic, there's no electronics for it on the card. Instead, the card slot in the camera has a small switch that engages with the lock tab, and the camera firmware uses the state of the switch to decide if the card is locked.

The switch could be stuck or defective. Since four different cards show locked, it's unlikely to be a card problem. In some cases, users have reported resolving issues like this by prodding the switch gently with a toothpick or similar (see https://chdk.setepontos.com/index.php?topic=3374.msg31113#msg31113 for example).

However, if your camera is still under warranty, getting Canon to fix it may be a better option.

ETA: If you do decide to poke around in the SD slot, it's a good idea to take the battery out too.

I tried to check right now but my sight doesn't help, and the fact it's deeply recessed in a very narrow /tight space doesn't help either. I think I saw the switch and tried to move with a toothpick, but it's really too hard being able to put under a favorable light to work properly. I'm only 46 y. o. and my eyes are already failing, plus i I have the bad habit to sweat for nothing and a few droplets come into play too.
