It's late at night, the parking lot is deserted, the only car there is yours, you reach into your bag, to find your keys missing, you panic, you start digging in your bag desperately thinking when you saw them last.
as you dig you see a glint in the bag, and it's your keys, your heart is pounding, you unlock your car, and sit there for a few minutes to calm down.
Step 1: The Solution
I have had this happen to me, I know what it's like!
So I went and found at Walmart, a metal pill bottle, ($5.00) that you wear around your neck,
I removed the bottom part of it, and then epoxied a small neodymium magnet, that fit into the top cap, attached it to my keys, and it magnetizes to one of the snaps in the bag.
