A key locking indicator apparatus for use in operating a lock, comprising:

• (a) finger engaging means for engagement by the fingers of a user including a body having an opening therein and a fulcrum disposed within said opening, said opening being defined by first and second pairs of inwardly sloping walls, said walls terminating in spaced apart first and second fulcrums;
• (b) a housing having walls defining a cavity for closely receiving the head portion of the key, said housing being receivable within the opening in said body with one of said walls thereof being in engagement with said fulcrums, said finger engaging means being movable relative to said housing between first and second positions;
• and
• (c) resistance means for yieldably resisting movement of said finger engaging means relative to said key member between said first and second positions.

A key indicator device for use with a key of standard configuration having ahead portion and a lock operating bit portion, said indicator comprising:

• (a) finger engaging means for engagement by the fingers of a user including a body having interconnected top, bottom and side walls, each said side wall having a fulcrum defining protuberance extending into said interior opening, one of said fulcrum defining protuberances having first and second grooves provided therein;
• (b) a housing having first and second walls defining a cavity for closely receiving the head portion of the key, said housing being receivable within the opening in said body, said first wall thereof being in engagement with said fulcrum, said finger engaging means being movable relative to said housing between first and second positions;
• (c) resistance means for yieldably resisting movement of said finger engaging means relative to said housing between said first and second positions, said resistance means comprising a rib formed on said second wall of said housing, said rib being alternately receivable within said grooves of said one of said fulcrum defining protuberances as said finger engaging means is movable between said first and second positions;
• and
• (d) indicating means for indicating whether said finger engaging means is in said first or second position.

• (a) finger engaging means for engagement by the fingers of a user including a body having a top, bottom and side walls defining an opening, each of said side walls having a fulcrum defining protuberance extending into said opening;
• (b) a housing having walls defining a cavity for closely receiving the head portion of the key, one of said walls of said housing being in engagement with one of said fulcrum defining protuberances, said finger engaging means being movable relative to said housing between first and second positions;
• and
• (c) resistance means for yieldably resisting movement of said finger engaging means relative to said housing from said first position to said second position.

A combination key and key locking indicator apparatus for use in operating a lock, comprising:

• (a) finger engaging means for engagement by the fingers of a user including a body having an opening therein and a fulcrum disposed within said opening, said body of said finger engaging means including first and second opposing sidewalls, said first and second side walls each having a fulcrum formed thereon;
• (b) a key-member, including a head portion and a lock operating bit portion, said head portion having at least one extending indicating protuberance, said head portion of said key member being receivable within the opening in said body between said fulcrums, said finger engaging means being movable relative to said key member between first and second positions;
• and
• (c) resistance means for yieldably resisting movement of said finger engaging means relative to said key member between said first and second positions.
