Remote is working, but not starting my car.

SOURCE: Remote starter stopped working

Will you rate my answer from my clarification as a solution about the antenna thanks Mike humble.

SOURCE: got a new remote for my viper 791XZ and reprogrammed it .

this usually means that the remote did not recieve a signal back from the module or the module did not recieve the remote signal
have you tried repeatively to press the unlock button? does the remote starter work or aux( trunk ) ?
also when putting the battery in the remote , be easy because there is a connector plug soldered on the board real close to where the battery is , and if it is hit by the battery hard enough it will cause those solder connections to disconnect and you will get the beeps and or other malfunctions

My battery ran low and I jump started my car which some how caused the problem. My viper technician made me a buy new remote but the problem continued even with the new remote.
Try disconnecting the battery of your car for ten minutes and then reconnecting it. It worked for me. Now i have a extra remote which i don't need.

sounds like the remots have lost two way communication. try to disconnect the windsheild antenna.try remotes again after pluging antenna back in.
