I have a 1999 Isuzu Rodeo, 129,000 miles, and I think a 3.2l v6 engine.

Anyway, I installed a brand new radio/dvd player/tv and now I can no longer use my buttons on my keys to lock/unlock the doors. I did not do any cutting of wires, I checked the anti-theft and power locks fuses and they are all good. I bought the correct wire harness, so like I said didn't have to do any cutting of wires at all. All I did was connect the color coded wires, plugged it in, and screwed the mounting stuff on. The radio and everything works, but the keyless don't. Any suggestions?
