Posted a Week ago '19 Silverado Locked.
 I had several good replies but nothing worked.
 Trucked it to Dealer that have ordered a key/ cylinder ignition switch.
  Interesting However they said could start it by lowering tilt wheel and 
 turn key at the bottom.
  Does seem to work but not sure how long.
  GM techs, is this normal? Just Dealers know this or a happen stance?
  Switch should be here early this week.
   Thoughts on this problem.  Thanks.
