SOURCE: key stuck, now new problem

There is a pin that goes thru the shift cable that is falling out. Above the window buttons pry the little plastic holder out remove the 2 screws take the plastic off of the sides of the console you will see a black plastic frame with holes in it I cut a larger hole between 2 of the small holes with a hack saw on the driver side. Put the car in neutral drivers seat all the way back pull on the shift button and you will see the pin pull it out with a pair of needle nose pliers. I put 598 black loctite sealant on mine and reinstall. Shift back to park if you can get the key out and the doors unlock you have the pin in the right spot and it is making both switches when in park. You can see if it is on the switches by looking thru the hole where the little holder came out. The pin sticks out about a 1/2" on each side. Good luck
