Hello,
If the alarm sounds when you unlock the car, the alarm system is either not receiving a proper disarm signal or one of the alarm input switches is showing an open/triggered condition. I would start by replacing the key fob battery and making sure the main vehicle battery is fully charged and load-tested. These cars can act strangely when battery voltage is low. Let me know how it goes
Please upload a short video in your response of the problem, so I can see what's going on?
