No Electrical Power When Car is Off

[logan1997]

I get acc power, but when the key isn’t inside the ignition and turned, I don’t get any power. If I try to lock the doors or pop the trunk using the electrical buttons without the key in, they do nothing. Any help is appreciated

I give up? What model year Mustang are we dealing with here? Electrically there are major differences from 1996-2004 model year.

I'm confused by your post. Is the base complaint about the door locks don't work with the key out? Or are you saying there is absolutely no power to anything with the key out? For example, do the head lights work?

For some model years the remote keyless entry is an option. For others it is standard.
