Few weeks ago after leaving sit over weekend battery was dead. Replaced battery, worked fine for a few days. After that occasionally the remote start would not work but would start perfect with the key except after starting I noticed the radio station was reset like the battery had died. Once tried starting and would not start just one 2 second click sound. After 3 attempts it started but the anti theft light was on. Shut off, restarted and was fine. Now my remote start does not work at all and most mornings when I start with the key it fires fine but again radio is reset like battery died after trying the remote start. Checked all fuses fine, no lights or switches left on.

Good morning

Yes, it sounds like the battery is being drawn down. There is a specific test for this. I attached a guide to follow for testing for this draw and how to determine the failure.
