I have a Panasonic CQ-DFX403U head unit. I had it installed at car toys, and of course, i didn't get the keys for the deck. From the looks of the manual, the keys are pretty specific to the deck. Anyone know any place where i can get the correct keys online? I want to pull it out so that i can install an amp on my front speakers. I have everything installed but the RCA cables, the remote start wire, and wire from the amp to the speakers.
