I'm thinking that toolboxes weigh something.  How about a strain gauge in the handle, going in you press the 'going in' button, coming out you check the 'going out' button, if the two weights are different, then do:
void toolcheck(weight_in, weight_out){
   if(weight_out >weight_in){printf( "sticky fingers"); high_beep()};
   if (weight_in>weight_out){printf("somethings missing"); low_beep()};
   printf("you're fine");nice_beep();
}
