I have an amazing suggestion. Get up.. and...LOOK FOR IT! Took me a long time to come to that answer. Enjoy my great wisdom that led to the answer of this difficult question.
Well, what other way is there? Do আপনি have a tracking chip in-planted in your remote? Nope. Th only option is to stop asking online and actually get up and look for it. If আপনি want the remote that bad, you'll find it..
That depends. When people lose things at my house they always come for me because I'm best finder but really I just remember and memorize where they put their things.
It really depends if I saw where they put their things. If that's not the case I look in the most obvious places first then the places আপনি wouldn't expect it.
