First honda, my sister owned it before me, when she first bought the car alarm worked fine even with an aftermarket radio, it stopped working right before i bought off of her. Remote lights up and all but no locks or sounds what so ever. Door locks work fine, interior light does not turn on when opening doors but it still does work, sister's boyfriend replaced both door switches before it was sold but it did not do anything. I checked fuses and they are all good. Just before she sold the car to me people tried to break in so she had a kill switch installed, whould this affect the alarm at all? any and all help will be appreciated, Thanks!
