Did kind soul walk Leaside clicking car fob to return keys?

A most heartening post at Leaside Community Facebook tells of the return of a woman’s car and house keys Thursday after they were lost nearly a month ago at Trace Manes Park. There are many unanswered questions most notably how did the good samaritan know to leave the keys between the front doors of the right home? The author of the posts makes a stab at it by saying the finder must have walked the area clicking the fob to see which car lights responded by flashing. Then the keys were left at the nearby house. Hmm. Maybe.
