just got the prerunner today. its an 05 4 door sport. i really love the truck. anyway, the previous owner put a flowmaster on it. it kinda has a drone to it that i think i will get tired of, but overall i love this thing. i noticed that when i use the remote to lock/unlock, there is no beep. not a big deal, but i like it to beep. does anybody know if it is a fuse issue or can you program it to beep? thanks for any answers.
