If the foil works then as mentioned, the conductive dots is wore out. Since I not sure which FOB you have, I have used both of these. My 06 GP has remote start and this is what worked:New Buick Pontiac Chevy Replacement Keyless Remote Case Button Pad Repair | eBay
My Granddaughter 06 GP did not have the remote start button and this one fit hers: New Buick Pontiac Chevy Replacement Button Pad Keyless Entry Key Remote Fob Fix | eBay
There is also a fix for an insert that has the foil on clear plastic bubbles that works on both. Lot of people just super glue a small piece of foil on the rubber pad. Both of the eBay ones worked, the one with remote start is real easy to push and sometimes while holding it in my hand I accidentally set off the alarm. Good news for the neighbors, I don't do bars anymore, bad news is I go to work at 5:30am in the morning. :-) The model for the grand daughter, she has not said good or bad.
I too had the dim radio controls. I found a source on eBay that has 20 of the clear bulbs for about $8 shipped. They are coming from China, so it will be awhile before I know how they work.
