I don't think I ever experienced the alarm on this car since I've owned it. For some reason today it caught my attention so wanted to see how it works. I closed all the windows and roof vent. Exited the car and hit the lock button. Went into the house for a few minutes. I returned with just the key out of the key fob and attempted to open the door manually. The door opened with no alarm? I left the remote in the house just to eliminate the system somehow recognizing it and tried again. Same thing.. nothing. Anything I'm missing? Any ideas? Thanks!
