If you wanted to decide where to locate your car wash, you might locate a spot on a map with lots of traffic, a parking lot, and a ready source of water. Locate means to find or place.
If your mother can never locate her keys, it means she loses them all of the time and has to look all around the house before going out. If you move to a new place, usually for a job, you relocate. But if you decide to find a job that is located in your town, you call that staying local, which, like locate, derives from the Latin locus meaning "place."
