That’s an interesting minor but significant difference. I’m from the UK, and both of my house keys (Yale, Abloy) have a distinct ‘right’ and ‘wrong’ orientation. Every house key I’ve ever had has been like this. The keys for my desk drawer and filing cabinets too.
I'm in Ireland, and most people have those keys too. But those things are too easy to open with a bump key. For the last 15 years I've insisted on proper secure locks and keys. The most I've ever had to pay to retrofit one is €90 (bought it in town and fitted it myself). I got 5 keys with that lock. My neighbour replaced his too, after I demonstrated a bump key to him.
Having a symmetrical key isn't something that I even cared about but I suppose it's a bonus.

Car keys don’t though, as far as I can remember.
