First off, you revived a thread that is over 13 years old. Secondly, there is no transmitter in the door. The transmitter is in the rear hatch area. If you have a 2000 and want to stay with the same set up, your best bet is to find a used one in a salvage yard. You can upgrade to to the 2001-2004 module, but again, you need to find a used one and buy new fobs etc. You can search that and see if you want to upgrade.

2020 C5 of the Year Winner- Unmodified
I just had my key fob stop working with my 2000 C5. Changed the battery in the fob. Still didn't work. Then I followed the reprogram system mentioned in the old posts. The Key Fob works fine now.

FOB training failed
This is exactly what happened to me. I replaced new batteries and tried FOB resynching and retraining on both of my remotes but neither worked. Any suggestion on what I can do next? Thanks
