Abstract: An organizing device including housing, cover, and sliding mechanism. The housing includes a cavity, at least one open end and at least one sliding mechanism opening extending in the longitudinal direction along the housing for receiving and retaining at least part of the sliding mechanism within the housing. The cover is removeably attached over the open end of the housing. Sliding mechanism includes an actuation portion or thumb actuator and mounting portion for mounting a key or other user device. The mounting portion of the sliding mechanism is positioned inside cavity of the housing and the actuation portion of the sliding mechanism extends though the sliding mechanism opening in the housing. In one implementation, the mounting mechanism may be permanently or removeably fixed to the user device. In the case of a key, the mounting mechanism may be mounted to the key blade to form the modified key.
