I have checked fuses and terminals everything is good. I know it will be a huge amount to repair at the dealer. My cv joint axle just snapped today for the 2nd time in two months. That being said I am looking for the most cost effective way to go about fixing this. My thought was to purchase an aftermarket alarm system w/ remote start and have that installed. My question is, can I disable the factory alarm to stop it from interfering with the aftermarket one? Does this make sense coming from my angle? Delete the malfunctioning stock alarm system and replace with an aftermarket system?
EDIT: BTW HAPPY EASTER!!!!!!!!!

How old is your automotive battery? Run TEST 9 on a cold engine (at least 2 hours after shut down)...with the ignition in position 1, see what the battery's voltage is.
If it is below 11.89 volts...your automotive battery may be giving you signs that it's time to replace it...and the alarm siren's battery is no longer getting recharged because the vehicles battery voltage is too low:
