I left my lights on and the battery died.
When I jumped the car, the radio went dead as well.
I tried to turn on HU, but it is not even asking for "code"
Initially, anti theft light was blinking but now it stopped blinking.
When I turn on lights, all radio control/buttons light up.
I checked the fuse next kick panel and the fuse is good.
I do have the code from the card the dealer gave me when I purchased s2k.

Any suggestions?

 

You need your radio code. The dealer may have wrote it in your manual. If not call a Honda dealer they can look it up.

 

Dealer won't give you the code over the phone. Gotta take the car in and prove ownership.

 

I have radio code.
The problem is that the radio is not even asking for it...

 

i'm not sure if the radio has an inline fuse
you may need to check if any fuses are blown

 

Check the fuse for the auxilliary power outlet (the "lighter" socket). It powers the radio also (2 sources of power to the radio).

 

I disconnected the battery, changed fuse for radio (15 amp) & aux (10 amp), reconnected the battery and turned on HU.
HU asked for code, entered it and it works now...

Thanks.

 

depends on dealership. i have gotten codes for my accord and friends honda over the phone
