I had to have a jump-start the other day and since then neither one of my key fobs works. I put new batteries in both with no change.

I'm guessing I need to have them reprogrammed but wanted to check with y'all before I go down that road. It looks like I can't reprogram them myself.

Thanks for the help.

Definitely try this... my roof stopped working after a jump start a few years ago... was kind of resigned to driving a rattly overweight coupe for a bit, but then figured I had nothing much to lose by trying a “hard reboot”... sure enough it did the trick. Good Luck!
