Are House Keys Magnetic and What Materials Are They Made Of?

[rockhouse]

What are they made of? Is it brass with a zinc coating? My son dropped our only house key through the slats on the porch and the only way to get it is possibly with a magnet...are keys magnetic?
I'm at work and there's no magnets around to try and see...thanks.

They're not generally magnetic, no.

If they're on one of those rings however, the ring is going to be magnetic.

Good luck fishing for them... :(

A coat hanger won't work?
