Basically a small, thin flathead screwdriver or other similar thing to gently pry the case open.

I found that prying the case open by inserting something in the crack will mark the case unnecessarily, and you might not even succeed. (otherwise known as the Phillistine method). The correct way is to open the key blade first, and then insert your thumbs in the recess where the blade tip was and then pry apart using thumbs only. The battery cover section will then pop off. It does take a bit of effort though.

No tools required - opened with thumb pressure alone!

Release the key from the recess and this is where to press against half the cover which is easy to prise open.

All well and good, but the cover on my fob is MASSIVELY tight and repeated attempts to pry it off with thumb pressure threatened to re-aggravate a thumb joint arthritic issue that took me over 6 months to get healed a couple of years ago...and it happened because I used my thumb to pry something else at that time and the joint finally said, "Fine, abuse me and you'll pay". I did.

I'm now using a small eyeglass screwdrive to pry the cover off. If it marks the fob, it's not going to ruin my day.

Rather than a watchmakers screwdriver use a 1/2inch wide or larger flat screwdriver in that gap/recess it should open for you and do less damage to the cover, best of luck.

Might be hard to get a larger screwdriver into that narrow crack. Trying to visualize what you are saying.

Midnight here in uk, Grenwich might tell the world what time to have your morning coffee and as much as I would like to advise further it will have to wait until later.
I will try a David Bailey (photo!) and post an attempt here later.
Pretty sure a visit to my garage at this time and explaining my need for a large screwdriver to my wife is not a conversation I could defend.

you put the wide blade into the wide groove then twist the screwdriver. One side of the blade contacting the battery cover, the other side pushing against the opposite side of the wide groove. No need to get into that narrow crack. You are using a tool to simulate what I achieve with thumbs.

Found the perfect option to open these - I have an old plastic freezer scraper in the garage.
I was checking for a piece of suitable wood scrap and this was among my tools.
No worry about damage to case and it is a simple twist to open.

Not damn! That's the solution. I've got one of those in the garage also. Thanks, Dave...you're a true innovator!

I was having a hard time finding anything the right size, then I thought to try a carpenter pencil.
Works good

I think a wooden "old school" ruler would work also.

For what it's worth there are proper tools for this task!
