Panic Mode?

[delbois]

I just returned from a shopping trip and locked the car (single press on fob) and about 2 minutes later the alarm went off - flashing lights and horn. I checked the car inside and out but could find no cause. I notice some Toyota key fobs have a Panic Mode button which remotely triggers the alarm. My fob only has the two buttons for open/close but I'm wondering if it's possible to invoke Panic Mode by pressing or holding the buttons, which may have happened as I was bending to put the shopping away with the fob in my pocket?

I had a moth inside the car, and the alarm went off whenever the street lights came on. Took an age before I spotted it and left it out, no problems after that. Just a thought. 

I've also locked and unlocked the car when bending down, I try and keep the key in a seperate pocket now
