I’ve had a 2003 Rav4 for 10 years. Only recently did I discover that there is an alarm system in it. Occasionally, if you try to unlock the door with the key and turn it to the left, the alarm will sound. It goes off once you turn the key to the right to unlock the door. Thus far, it has never beeped when we lock the door.
This morning, for the first time ever the car began sounding 2 beeps when we manually unlocked the door and 1 beep when we lock it. (We don’t have a fob) The alarm sounds if we open an unlocked door without first disabling it with the key. It is basically going off everytime we try to get into the car. It is incredibly annoying.
What happened? Any idea what triggered the system to come out of hibernation? And how do we send it back to sleep?
