interesting viper 791vx problem

now before i start, i'll say that i did do a search and came up with a few threads that were close to this problem, but none that were the same. i have the viper vx791 with the responder remote. about 5 days ago, either my remote or the alarm itself stopped communicating. I already changed the battery. I can still press the AUX button to open my trunk with no problems as well as the remote start. I can not arm and disarm the alarm though. When I press the arm or disarm buttons I get the 3 beep code on the keyfob indicating that communication failed. My thoughts are that the remote is bad. That doesn't explain why I can use the AUX button and the remote responds to me pressing the arm and disarm buttons though. I then thought that it was the receiver, but like I said, I can still open the trunk. any ideas?Cuz I'm Kewl Like That.

well, I disconnected and reconnected the antenna on both ends and still nothing. I traced the wires of the antenna and they're good. I took apart the brain box, looks like the solder points are fine. Same with the antenna box. is there a battery in the brain? I didn't notice while I was looking at it. would the battery in the brain cause this? I also took apart the remote and everything is fine.Cuz I'm Kewl Like That.

Sounds like your remote is bad. Try reprogramming the remote to the brain and see if it doesn't help.Installer, IT support, and FFL. I need less hobbies.

I do not beleive there are any batteries inside anything other than the remote.  Like twelvoltz said, try reprogramming the remote.I'm not a professional installer. But I did stay at a Holiday Inn Express.

I believe that the AUX channel is NOT a code hopping channel.  If the remote is 'off track' with the receiver then you'll experiance what you are experiancing.  Try reprogramming the remote.Kevin Pierson

anybody got a step by step on reprogramming? thanks for all the help btw.Cuz I'm Kewl Like That.
