I recently installed a subwoofer and component speakers per another members instructions that i found. Shortly after i starting having a problem. The car will lock fine but the vehicle won't unlock if i press the unlock button on the remote. The turn signal lights show that it is registering the informaion but it won't unlock or turn the alarm off.

Need help, local car dealer is trying to screw me by saying he reset the system but only removed the horn and left the horn in the passenger seat.
