No, we really literally mean a key magnet. As in, you can toss out your by-the-door key hooks and let your light swtich plates tackle the job. This DIY project is stupid easy, and you could probably get it done in less than a minute with supplies from the bottom of your junk drawer. We're filing this multi-tasking organizational hack into the "why didn't I think of that?" file.
Those cheap, builder-supply light switches you probably have (and loathe) in your apartment are the secret to this easy-as-pie home hack: They're lightweight enough that a strong magnet can power through them.
Instructables user instructablesar was sick of his wife taking up both of their family's key hooks. He took matters into his own hands and wedged a small, but powerful, neodymium magnet behind the plastic plate of their light switch.
Now, his key ring hangs automagically from the light switch, and his happy wife gets to keep both key hooks to herself.
If you want to replicate this hack, remove your switch plates and try out the strength of your magnet to see if it can hang on to your car keys through the plate. If it works, you're good to go! Wedge it in underneath the plate like instructablesar did, or just glue or tape it to the back of the plastic plate. Voila!
