Lost the house keys. How to find it?

oppps. that's very dangerous...someone might find it and may resort getting inside your house without your knowledge.

i advise you to immediately change your door locks so as to prevent intruders.

maybe you can go to the police for help.try to think about where you went to and back to the place

there is no way for me to find a house key once i lost. ithe only thing i do is to ake another duplicate copy i usually keep the key on the cabinet. i only use the duplicate copy. so i don't really lost the key on my cabinet since i don't or i rarely touch it. it is like a back up key. i have to back up keys. and a lot of duplicate keys. sometimes i have 4 duplicate keys. since it's not really expensive to have a duplicate copy.
