So I installed a aftermarket remote (CM-DC3) start in my 2008 Honda Odyssey. After the installation I have an issue where the keyfob will only unlock/lock if the car is on. My OEM keyfob also no longer works at all. My suspicion is maybe a fuse blew somewhere, but I can't seem to find any fuse specific to this. Does anyone know what might be wrong?

 

The aftermarket remote may have interfered with the Honda set up.
It seems the fuse tap for aftermarket remote might be on a fuse that is only hot when engine on??
Short of that then would be a fuse.
Best to use test light or multi meter
Each fuse has two test pints. One above each leg of the fuse.
Neg clip to ground or battery neg
The probe to each test point
If both side light up then fuse is good
If only one side then fuse is blown
If no lights then no power to fuse

There is a re-learn for the original key fobs
