I concur with Cycle7447. On pre 2014, it’s ignition switch 3 times, left turn 3 times and right turn once, to display/change pin.
Pre 2014, it won’t read “enter pin”. Without fob present, turn on ignition and press both turn signal switches simultaneously. Then immediately you begin to enter your existing pin#.
You probably already knew that. You didn’t mention whether you have the pin# or you wanted to retrieve it so you that you could change it. I’ll back off now, nothing else to offer. Good luck!
