Character: “Kei” For “To Go” (去) In Sichuanese 怎么在四川说话居然还会听不懂了


  宜宾话和很多四川其他地方的话有代沟的，比如去字，宜宾读kei成都以南大多读ji以北读qi网上读qie





  广安人表示也都kei





  呵呵，就是，克耍。有些字眼他们真的不懂了


宜宾方言


  出克：外出



克 seems to be the substitute character for kei but is there a REAL character for this word?
As Claw says, 去 is the historical character for it. This could come from 文白异读, that is, literary/colloquial readings. That would make sense, because colloquial readings are often either more innovative, or are a throwback.

Another option would be borrowing it from another variety, e.g. Cantonese keoi.
