No answer, but had same problem buick fixed it once. Buick said it was a "grounding problem" ..., now its back

I had the same problem replaced the battery in the remote and still would not work. I ended up scraping the contacts inside the remote with a pocket knife to remove whatever coating had developed and it fixed the problem. surprisingly had the same exact problem with a second remote and the same fix cleaned the contacts and new battery for good measure .
