Nope although I should make a copy for my sister and boyfriend...

My parents hide their extra key in the garage fridge, in the butter holder. For some reason I think it's hilarious they hide it on the butter shelf.

We don't hide a key on our property, but my In-Laws have keys to our house and they live only 10 minutes away.

I don't really do that but when my sister lived nearby, she had a set of my keys. I think it's really silly when people do things as hiding keys under a rock and stuff. If someone's trying to break in, I'm sure they wouldn't have much trouble finding a key in those spots.

I do have a set hidden; however, even if they found those keys, they don't know the alarm code.

We have a hidden key, but the one time we needed to use it, it was in the house and we had to pay $150 for a locksmith. Thankfully we just picked up lunch, so we sat in the backyard eating waiting the the locksmith to show up.

I have an extra set, I just don't know where they are

I don't. Though, there has been a few times where I wish I did, because I've locked myself out a few times... luckily my friend is a locksmith!

I have an extra set, but I don't hide them. They are IN the house.

I lost my keys once and was surprised how easily I broke in.

no... but some times i wish i did... last time i locked my self out i had to jump though a window! i felt like i was a robber!!!lol
also my dad hides money in the freezer....lol
and says this realy lame joke 'theres noting like cold cash!'
and i only laugh at him coz it was lame!

A couple of my friends & my sister have an extra set of my keys. I did it after I got locked out of my place when I'd lived there only a few weeks, fun times!
