I didn't have to do this cause my switch still works but was intermittent... but if the switch is not responding I'm pretty sure you could just by pass the switch by attaching the orange and blue wires together (by soldering or a wire nut or whatever works) constantly giving the solenoid under the ignition key power whenever the key is in accessories. The down side is that it'll let you pull the key out in any gear.. which it's only supposed to do in park...which is basically what the original poster did with zip ties.
The switch i'm talking about is at the bottom and to the right of the auto shifter (follow the original poster directions with the link below to get there).... It's the square piece with a metal clip at the bottom of it and it's held in place with 2 clips one on the left and one on the right...it's the last pic in the guys post:
How To: Fix locked key due to parking switch - Automatics only
The switch releases the key when the auto shifter is put into park when the right pin comes up and pushes the metal clip on the switch inward toward the switch which pushes a small button underneath the metal clip. But if the switch works like mine did but it's intermittent (you can check if it workds by pushing the metal clip in toward the switch...you might hear a click from the switch and in the steering column and it will let you take the key out in any gear)...this is what I did but if your not careful you could damage it permanently. I CAREFULLY bent the metal clip on the switch BY SUPPORTING THE BOTTOM AND BENDING THE END OF IT away from the switch. This will cause the right metal pin to come in contact with the metal clip sooner and it'll push the button underneath sooner. If you want to remove the switch from the platic clip that holds it there are two clips that hold the switch in place one on the left and one on the right. You have to push both of them out then pull the switch out...the last pic show a good view of it....how to get it out is up to you.
Hope this might help someone...
