If it doesn't correct itself you may have to bring it to a person with a scanner that can reprogram keys for you

Could the ignition switch be bad

have you checked the evic. if you have a overhead consul with the ignition of press and hold the c/t and reset buttons simultaneously and while holding them switch on the ignition. if you get a J1850 message your can bus has a fault causing the skim light to illuminate..
