bad CPU type in executable: svg2key

Run this command in the Terminal, it should return one or two results depending on if the executable is a Universal binary or not:

file /path/to/svg2key

svg2key: Mach-O 64-bit executable arm64

svg2key: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64:Mach-O 64-bit executable arm64]

If it reports anything else, it is not a compatible binary for an M1 Mac. You will need Rosetta2 installed to run X86_64 only binaries on an M1 Mac, and then only if they are supported by Rosetta2 which it would prompt you to install when attempting to run an X86_64 binary.

Or, you are running a 32-bit compiled application which is verboten on M1 Macs.

If I’ve found the right origin for that app…

That app was seemingly built for OS X 10.4.

It’s old, and very likely is 32-bit. If so, it won’t run on current macOS.

It’ll need to be rebuilt for 64-bit. Which can be easy, or can be intractable.

This alternative app looks more likely to work:
