Door locks won't work

[Conn SVX]

Help I locked my car went into the store and when I came out I could not un lock it. I climbed thu from the Pass side when I got home the door will not unlock from inside or outside. If I put down the window turn the key to un lock pull up on the inside unlocker and pull up on the out side door handel it will open. Any suggestion seems like something slipped. Auto door lock remote is shot. Had this happen once before but forgot how i cured it.
