Check your antenna, should be mounted on the windshield. unplug it for a couple of minutes and then plug it back in, then check the remote. make sure the alarm has power, try putting the alarm in valet mode, if it goes into valet with no problem then the alarm is fine, then you can re-program the remote. if it doesn't go into valet then the problem may be the alarm and not the remote. hope that helps, dave
