ID this gas cap key?

[Stevehose]

I have this style cap but no key and would like to get one, it looks like 9151 but I can't find anyting on it.

Anyone know this make/model key?

That looks like the gas cap on my coupe but the key looks a little different

I have two of these caps, one key is HK brand code C6 which looks very similar, the other key is newer and very different but still an HK, code K03. Coupe is on left.

I have the same 2 caps and keys as Chris. HK...with codes C5 and K15. Believe the right cap/key were the later units.

Do you know where to find blanks? I can't find any info on HK keys. Do they cross over with Ilco or any others?

Any good locksmith should have a match.
