rs is starting to fail

Howdy...any ideas/opinions would be cool... I've had the same remote starter for a few years, and everything has been working fine. A few months back it was acting up, so I replaced the battery and it didn't do anything. The remote was in bad shape, so I bought a new one from ebay, and it worked fine for a while. What's strange is that now, every button on there (there's 4) works fine except for the remote start. Every once in a while it works perfect when I come out to my car (maybe very early in the morning), but usually it doesn't even respond. AND, sometimes when it does remotely start and then I do another action like remotely roll down the windows, or unlock the car, it shuts off. I tried re-learning the tach, but that didn't seem to do anything. Any other ideas? Thanks!

It's a Viper 550esp. When it was acting up, the remote and the alarm just weren't playing nice anymore. You would hit the remote buttons and the green light would light up, but nothing would happen. I would stand there for a few minutes and just keep hitting buttons, and nothing. All 4 buttons were acting this way. What's strange is that if I left the remote's case open a bit, it would work a little better....so I just figured the circuit board was messed up. It seemed to go away for a while when I replaced the remote....but now everything works fine but the remote start button.

Does the unit give you any fail codes  (thru the LED)

I'm assuming you mean like when someone bumps the car and sets off the alarm, then the next time you unlock the car it will beep and blink differently?.....nope, no fail codes. Isn't there some kind of voltage sense thingie that sets off the alarm if something happens like the headlights turn on, etc? Just trying to think of everything.

I'm leaning more towards the keyfobThe search function is your friend.

Do you have an ON/OFF switch under the dash area for the remote start. It may have been hit into the OFF position.

Can you think of a way to rule out the fob, or to rule out the brain? I can't at the moment.

Thanks for the idea...I do have that switch, but it's in the ON position for the starter. And sometimes it starts and sometimes it doesn't. Maybe I should at least check that ground connection. What's strange is that my radio reception (yes, still use radio sometimes) is getting crapier and crapier....not sure if it's related or if my antenna is just dying.
