My 88 560 sel alarm will not disarm? I have the key with red dot How can I reset alarm

try this. When the alarm is going off, open the door and put the key in then turn in the unlock position. Thank should turn it off. If not then you have something wrong with the system. Under the drivers seat, the alarm module is under there so you can temporarily or permanently disable it

Try disarming it from the passenger side or the trunk.
