What is the ruling on men and young men wearing a silver bracelet if it is used to hold keys?

It is not permissible for men to wear chains or bracelets for adornment, whether they are made of silver or any other material, because this constitutes imitation of women. Imam An-Nawawi explicitly stated the prohibition of all women's ornaments for men, except for a silver ring, because these are specific to women. Furthermore, the Prophet, peace and blessings be upon him, cursed men who imitate women. If the chains are made of silver, another prohibition is added regarding the use of silver for men in ways not permitted, such as a ring or for medical necessity. It is also not permissible to use them as key holders.
