I just installed some subwoofers and an amp in the trunk of my '94 GS-R, and now the keyless entry/alarm doesn't work. the funny thing is, when you hold down the lock/unlock button on the remote, it still successfully sets off the alarm like it's supposed to. I didn't do any electrical modifications other than adding a power wire to the battery for the amp, and splicing a wire into the power antenna wire to turn on the amp. Anybody have any suggestions? I would like to be able to use my alarm again.

 

Maybe You should plug in Your battery.

 

My battery was plugged in, you know that. However, for anyone who has this problem, I did figure out what it was -- Valet Mode. (whoops) It seems that i had accidentally engaged the valet mode without knowing it.
