08 fxdc red light stays on, tssm issue?

Can anyone help me with my issue before I spend a mint at the stealership...??
My red key light stays on, security of bike is demobilized, alarm won't even chirp engage. Turn bike on, headlight and tail light come on...turn to run and fuel injection engages. Red key light comes on and stays on, can't start bike. Tried to clear codes of tssm, it reads no rsp.
Yes everything else is good, new fuses, new battery fully charged, and new fob battery. I'm at a lose and getting quite frustrated. Anyone else have this issue? Is it fixable without a harley dealership computer diagnostic? Thanks in advance...Derek.

I don't have an audible alarm but don't they use a 9 volt battery for power? Maybe the alarm battery is dead.

Have it at a shop and he hooked to a computer, no codes showing anywhere. Bike is just straight up demobilized.

I'd suspect the TSSM is dead, but I really have no experience with that. You'd think the other modules would set codes for loss of communication with the TSSM, but I definitely could be wrong.
