The battery in my 2005 300C died completely (don't ask) and now none of my key fobs work. Is there a procedure to program the car / fobs that doesn't require having at least one working fob? Thanks.

You don't need to reprogram after replacing the battery. You might have other problems with it.

Sounds likely. The battery in my '06 C died at 81K and 7 1/2 years. The fobs weren't affected.
