i have an 05 civic lx and i recently upgraded the sound system. i later found out that because of this my security doesn't work properly. thing is though i need the old head unit to enter the "radio code". my question is, is there another way to enter the code? i obviously cant do it from my new unit. any ideas? suggestions?

Radio code is only used to prevent theft of your stock head unit
it has nothing to do with your alarm system

My guess is, you, or whoever you let do your sound system messed up the wiring
