I saw a few members were having issues with their Keyless go button on the shifter. My wifes CL55 has this same problem so I decided to fix it. It takes about 15 minutes to repair and doesn't cost a dime. I will include pictures of the repair and show how I fixed the problem. Her car would start sometimes with the button and other times you had to press the button and move it around a little to get it to start or stop. I removed the button and found that the issue is the two prongs going into the switch were not making good contact with the circuit board. I simply took a small punch and very lightly (and I mean oh so very lightly) tapped the solder points where the prongs come through the circuit to close up the holes and then reinstalled the circuit board and button. While I had the micro switch removed I poured a small glass of alcohol and submerged it and continued clicking it till it was clean. Blow it out afterwards and let dry. Now it simply takes a touch and her car starts as new! Hope this is helpful to all out there instead of the crazy prices they ask for these shifter knobs.

When removing chrome button support on both sides and gently pry up. I used a very flat and smooth clay working tool bought at hobby lobby in a small set. Make sure you get a good engagement so you don't hurt your chrome edge on the button. If the circuit board stays in the knob simply gently remove it with a pair of needle nose pliers. One end is under a black plastic tab and the board end needs to be placed under this before pushing over the prongs. Then simply push the chrome button back in place. It seem the prongs work the solder on the board over time and loosen up and don't make contact.

I thought I would update this. The switch started acting up again and I traced it to the contact lugs coming through the circuit board. I ended up just soldering the pins to the board and this took care of any rocking motion the board had and it once again starts instantly when pressing the button.
