Soldato
There are two different versions, one with a rim lock and the other with a euro cylinder.Top man thank you. Apparently there is a keyed alike product on Amazon so I'll do a bit of research.
I thought perhaps you could replace the euro cylinder with one to match the house, but apparently these have 10 tooth cogs which aren't common.
You can probably get multiple locks with the same bitting, but I bought mine at different times.
Good locks though and easy enough to fit.
