Abstract

Embodiments of reminder apparatuses (e.g., configured to be coupled to a key).

1 . An apparatus comprising:
 a body having an opening configured to receive a key, and an indicator having a plurality of indications and configured such that one or more one of the plurality of indications can be selected to be viewable by a user;   where the body is configured to be removably coupled to a key such that a portion of the key extends into the opening and the body resists removal of the key.   
     
     
         2 . The apparatus of  claim 1 , where the body has a first end and a second end, and is configured such that the opening extends through the first end and toward the second end, but does not extend through the second end. 
     
     
         3 . The apparatus of  claim 1 , further comprising:
 a holder having a first end configured to be coupled to a key ring, a second end configured to extend into the opening of the body such that the body resists removal of the holder.   
     
     
         4 . The apparatus of  claim 3 , where at least one of the body and the holder comprises a child-resistant lock configured to couple the body to the holder such that at least one of compressive and rotational forces are required to separate the body from the holder. 
     
     
         5 . The apparatus of  claim 1 , where the indicator is configured such that the indications can be customized by a user. 
     
     
         6 . The apparatus of  claim 1 , where the body comprises:
 an outer member having a sidewall defining an elongated channel and a window extending through the sidewall in communication with the elongated channel; and   an insert configured to be disposed within the elongated channel, the insert defining the opening of the body, the opening having an elongated cross-sectional shape that is smaller than the cross-sectional shape of the elongated channel.   
     
     
         7 . The apparatus of  claim 6 , where the insert is resilient. 
     
     
         8 . The apparatus of  claim 6 , where the indicator is configured such that an indication can be mechanically selected from the plurality of indications. 
     
     
         9 . The apparatus of  claim 8 , where the indicator comprises a sleeve having an outer surface with the plurality of indications, the sleeve movably disposed between the outer member and the insert such that the sleeve can be moved to cause different ones of the plurality of indications to be viewable by a user. 
     
     
         10 . The apparatus of  claim 9 , where:
 the outer member has a slot extending through the sidewall in communication with the elongated channel;   the sleeve has one or more protrusions extending from the outer surface such that the one or more protrusions extend into the slot; and   the apparatus is configured such that the one or more protrusions can be moved relative to the outer member to cause the sleeve to move relative to the outer member to select at least one indication to be viewable by a user.   
     
     
         11 . The apparatus of  claim 1 , where the indicator is configured such that an indication can be electronically selected from the plurality of indications. 
     
     
         12 . The apparatus of  claim 11 , where the indicator comprises a display coupled to the outer member, a selector, and a memory programmable with the plurality of indications such that the selector can be activated to cause different ones of the plurality of indications to be displayed on the display. 
     
     
         13 . The apparatus of  claim 11 , where the indicator comprises a speaker, a selector, and a memory configured to store the plurality of indications such that the selector can be activated to cause different ones of the plurality of indications to be played audibly through the speaker. 
     
     
         14 . The apparatus of  claim 13 , where the indicator comprises a microphone and the memory is configured to receive and store a custom indication such that the custom indication can be played audibly through the speaker. 
     
     
         15 . A method comprising:
 providing an apparatus comprising:
 a body having an opening configured to receive a key, and an indicator having a plurality of indications and configured such that one or more one of the plurality of indications can be selected to be viewable by a user; 
 where the body is configured to be removably coupled to a key such that a portion of the key extends into the opening and the body resists removal of the key; 
   selecting one or more of the plurality of indications to be viewable; and   coupling the body to a key such that a portion of the key extends into the opening and the body resists removal of the key.   
     
     
         16 . The method of  claim 15 , where coupling is performed prior to selecting. 
     
     
         17 . The method of  claim 15 , where the key is a car key. 
     
     
         18 . The method of  claim 15 , further comprising;
 removing the body from the key; and   coupling the body to a second key such that a portion of the second key extends into the opening and the body resists removal of the second key.   
     
     
         19 . The method of  claim 15 , where the apparatus comprises: a holder having a first end configured to be coupled to a key ring, a second end configured to extend into the opening of the body such that the body resists removal of the key; and the method further comprises:
 removing the body from the key; and   coupling the body to the holder such that the second end of the holder extends into the opening and the body resists removal of the holder.   
     
     
         20 . A method comprising:
 providing an apparatus of  claim 1 ;   selecting one or more of the plurality of indications to be viewable;   coupling the body to a key such that a portion of the key extends into the opening and the body resists removal of the key.
