My 2000 Grand Prix GTP's keyless entry seems to not be working properly. I replaced the battery on the remote and it still did not work. I changed the #29 fuse and then the keyless entry started working again for about 2 days and then it stopped working again. I inspected the fuse and it did not appear to be blown but I replace it again and then it started working again for about a day and now it has stopped working. Anyone have any thoughts as to what the problem could be?

Thanks,
Craig
