I owned my '95 sedan for about 7 years now. The stock alarm worked for maybe three years and then stopped working. When it did work, I would have to leave the key in the keyhole for two seconds and then turn to unlock the doors. The alarm also went off when the doors were locked and then opened from inside. I can now put the key in and immediately turn to open the locks without the alarm going off, and I can open the locks from inside while the doors are locked without the alarm going off. Whenever the doors are locked the security led flashes showing that the alarm is activated, but it still does not work. My question is, why???
