Keys Please, Take 2!

Alright, so...after my last excursion with my keys, the next day, I went a bought a magnet key holder for under my car. Since my last wonderful experience, I put the magnet on my refrigerator, in hopes that I might remember it and put it under my car. About 2 weeks ago, I took it out to my car and put it in my car. Last night, I did it again. I locked my keys in my car, again, last night. And where was my magnet?????

...Needless to say, it's under my car now, FINALLY!
