ABSTRACT:
The present invention provides a key capable of being rapidly and efficiently identified by the user, whether in a lighted or dark environment. In a number of preferred embodiments of this invention, the key carries a panel or strip on which the user, at his or her option, may apply indicia in the form of a name, identification of the cooperative cylinder lock with which the key is associated, or, by way of example only, a decorative symbol which may catch the user's fancy or political persuasion. Magnifying, duplicate viewing and phosphorescent-type members are contemplated as coming within the scope of this invention, as are small tactile projections which are capable of being used and/or changed by the user to identify the key without actually viewing it.
