Nice colour frame, what is it?
Happy to be wrong! 😀
Well my hack saw went through a hardened steel Abus D lock shackle just fine, an axle is not so different. Took a new blade. But when your son has lost the spare key as well as the main, you’d be surprised what you can do with a big vise and a bit of effort. Next step would have been a portable angle grinder, but I thought I’d spare the investment.
A good quality bi-metal hacksaw blade will cut hardened steel, although it'll take a bit of work to do.

bb removal use a big g-clamp to hold the splined tool firmly in place so it doesn’t slip off / mash the splines.
I always just put the crank bolt back on the BB to hold the tool on.
The bb was NOT the issue - it was the CRANK ARM
