Changing the default location (latitude and longitude) of the Store Locator can be done in two ways. Firstly, you can simply go to the “ASL Settings” tab and change the Default Lat/Lng field, as shown in the image.

Another way to do it is by adding the attribute of default_lat and default_lng in your shortcode.
For example:
[ASL_STORELOCATOR default_lat="xxxxx" default_lng="xxxxx"]
