[header] How to hide diary keys [title] Hide your diary keys in the battery compartment at the bottom of a clock. [step] This is the last place someone would look to find your diary keys. This is also a very good and simple place to put your keys if you have nowhere else to hide them. 
[substeps] Keep in mind that this only works with battery operated clocks and the standard clock you would put on a shelf, rather than a clock you would hang on a wall. Clocks like these can be found at a local store near you.
