Hey fellas!

Got a little (or huge) problem. Today my car alarm turned on out of nowhere and it won't turn off. I had to pull the fuze (red 10), which also deactivated the lights within and locking/opening the car with the key fob. I don't know what caused this, but I might nead a hearing aid now, since this chirping sound definitely was not very comfortable to my ears
Can somebody point me in the right direction please?

Thank for your response!

Nick
