UPDATE: Trailer park landlord has them. Will get them tomorrow.

We'll keep an eye out for ya

Hope you fine them soon. I hate when I lose common items

Isn't this the second time you have lost them? Or last time you posted that you locked them in the car ...

If you think they are outside, find out if any of your friends have a metal detector. Longshot, I know. You can also use a big magnet from a speaker, hang it from some twine and section your yard with it just above the grass. Hopefully it'll grab your keys.

But the odds are that they'll be underneath the big pile of siding you just created.

DON'T do the mowing until they turn up, I'll bet a mower would put a key-ring and keys into orbit. Or through your leg...

The last time I remember having them was going to the mailbox. And they're nowhere around there. I've looked every possible place and dug up the pile of siding I made. NOTHING.

I feel someone might've found them and have them right now.

I don't know what to do now :(

This is the exact reason I always keep a spare set somewhere.

Good luck, I HATE it when I lose something.

did you go inside at all? could they be in there?

This might sound stupid, but I did it once... Did you have a lot of mail? I set my keys on/in the mailbox once to carry it all and completely forgot about them...
