If they both stopped working at the same time, you likely will need the dealer to reprogram them to the car. If they stopped working one at a time, the problem is likely due to either broken battery bracket contacts, or worn out "carbon" contacts inside, that contact the circuit board.
Here is the link to the solder job to fix the battery bracket - https://www.chevyhhr.net/forums/show...ht=cold+solder
and here is the link to a fix for the "carbon" contact issue:

Hope that helps.

The 2008s have a problem with the Remote receiver loosing programming; it might be bad since both transmitters stopped working at the same time. Is anything else not working? Like the TPMS. If so, it probably is the receiver located above the headliner needs reprogramming.

After reading how apparently fragile these fobs are, when I found mine in the washing machine, after it had been through a complete wash, rinse and spin cycle, I figured it was toast. So far it has been and continues to work just fine, which was quite surprising to me. Today is day three, and still working. It is clean, though!
