Problem I had with my 5701 viper remote was the battery. The connection sucked. Was constantly resetting. Would lose contact all the damn time. You could just set it on the counter and it would sit there and wig out. Try to unlock the door and you have to hit the button 13 times and time it just right when it was having its fits. Finally took the back off and bent the contact and used electrical tape to tape it tight.
Had my compustar for 5 years. Never a problem.
Oh. Had the same problem smiggs did too. Parasitic drain somewhere after install that was unexplained. Brain was replaced under warranty. Same issue
mine had the same draw, something to do with the antenna I believe.
