Key assist devices for enabling a user to conveniently and repeatedly attach a key to a key ring's split ring and detach it therefrom and, during its detachment, securely clamp the key to a clothing item for safely carrying the key. The key assist devices include a spring clip with the interchangeability functionality of freely and directly suspending a key from a key ring's split ring and clamping the key on a clothing item.
