i lost my lumia 640xl and i want to lock it, if possible try to find it! how do i find it,track it or lock it!?
Look in settings for find my phone. The rest guides itself
A little tough to do if your phone is lost.
OP you'll have to log in to your Microsoft account from any desktop if possible and erase it from there under "your devices" if it's listed.
Sorry didn't read it well
