Alarm sign blinking on 2011 Toyota Corolla

Dear repairpal,

my corolla 2011 s alarm sign blinking all the time. Usually is not like this. I think the alarm is on valey parking mode, even the sound of the alarm when I lock or unlock the door is different.

Do you know how to put back to alarm regular mode instead of on valey parking mode. THank you so much

Factory or dealer installed/aftermarket alarm? If factory do you have owners manual? Under warranty if electrical fault ?
