My remote will not lock or unlock my doors, nor will it remote start, nor will the panic alarm work. I have changed my battery and there is no indication on the dash that it does not work.

Did you install the battery the correct way? If you reversed polarity the remote will not work.

Yes....it worked once on one remote and nothing on second remote with new batteries....both remotes just seem to have issues at the same time....also having to dbl and triple press lock and unlock....panic button will not work at all..???

i had changed new bateries, but still dont lock or unlock my doors
