I keep losing my keys

One very reasonable thing you can do is attache your keys
to your belt using a medium weight chain. I find it very
convenient for someone who is always on the go. Try it now.

Hi, you could try attaching a large key fob/ ring to the bunch of keys - something that is large enough so that you cant miss it - but small enough not to be too big to fit in you bag or pocket.
When at home, you could have a special 'key place' to put them - i hand mine on a hook in the kitchen - and thats where they live!
HTH

There are products that you can attach to your key ring and there will be a remote that you can press a button and the keys will beep. I would look into those. Or you could try having a large rasp or a number of attachments on your key ring to make it harder to lose in the first place.

try to make it a habit to hang your keys in one place at home, that is what i usually do with my car keys. everytime i arrive home i just hang it there so it doesn't get misplaced. if you are going somewhere else all the time, buy a keychain with a hook so that you can just hook your keys to your pants or bag or whatever that you always carry with you.
