What I would do is..get a big linked chain for the braclet..make it to the lengh you want it..attach a clasp..then either make clay keys..paint them the colors you want.Make sure you seal the paint..i like to use glitter mode podge sealer sometimes..or make stacked paper keys...find a key pattern or draw a key pattern on a piece of heavy paper . then cut several pieces out of paper..i like to use file cards. this doesnt take as many for a stack..let it set for awhile to dry..then paint the keys the the colors you want..and repeat the above like the clay keys...put jump rings at the top and hook onto the bracelet..stacked glued paper dries hard and when painted you can't even tell its paper.
