Your dealer put an aftermarket alarm system on your car. Have it removed; they're nothing but trouble and add nothing of value.
Many of those "alarms" just plug into the OBD port; five minute job at the most. Check your OBD port to see if there is something added there.what? This is actually a thing? One thing I didn’t mention is that I picked this car up the day it came off the truck. Had about 8 miles on it so I doubt they put an alarm on it knowing I was coming down to pick it up asap. The memory seats were not working at first but I figured out that they need to be calibrated which the dealer or manufacturer does. I’m wondering what else has to be setup or calibrated. So lost. Scoured the internet but can’t find anyone with the same issue. The service rep at Toyota had no clue either.
