I have two Lexuses.
Both of their alarms went off randomly this year for different reasons.
Luckily, one of my friends told me there is an internal sensor so you don't fall asleep in the locked car, or leave a child or animal inside to cook.
I figured out one reason was my sun screen I put in the windscreen to block the sun when parked sometimes falls down. The movement sets off the alarm. Okay - no more sun screen!
My other Lexus' alarm went off last night and tonight. Very embarrassing as our neighbors are very close. I went out to examine and found a grasshopper flying around inside the car. Obviously the motion sensor picked that up! So - check for bugs in your car or just spray insecticide if you are desperate.

[QUOTE=ChitChat;5472087]So why do you think my alarm went off for no explainable reason today? My car is parked in front of my house and all of a sudden I hear an alarm going off. Now, I've never heard my own alarm so I wasn't even aware it was mine until it kept going and I realized it might be mine. So I went to look out the window and I couldn't decipher where the sound was coming from because there's a lot of cars around here (I just woke up and I wasn't dressed to go outside). So for the heck of it, I grabbed my fob and kept pressing buttons to see if it would go off. I was so flustered and nothing went off so I thought it wasn't mine. Then I held down the red button and it finally went off. Embarassing because all the neighbors were looking out their windows. LOL
Has this happened to anyone for no reason? Does it mean someone tried to open my door (which I doubt because it's broad daylight in a quiet neighborhood). What warnings should I look for on the dash when I go in there for the first time after shutting off the alarm?[/QUOTE]
