Today when I woke up I couldn't find my keys (car + car alarm + house + job + key chain, all together).
I know that they should be somewhere around my house or garage, because last night I returned home driving. I always try to leave them on my desk, but couldn't find them there.
I searched like crazy in the morning, but with no success (was stressed out and running late). What alternatives do I have to effectively search and find my lost keys?
I already plan to search everywhere again with calm mindset, and try to recall where they could be, but I wonder if there is a more effective or efficient way of doing it, as I am short on ideas (taking advantage of the fact that they are metallic/electronic, perhaps).
What do you suggest?
Note: I also thoroughly checked inside my car (luckily the window was halfway down to open it), but no success again.
