Why do all of my windows on my 2005 ES330 open when the car is in my garage?

All lexus models after 2005 have a feature if you hold the unlock button on your key for 5 seconds all passenger windows will open until u release ur finger from holding unlock button. If u let go of the unlock button after windows are half way down they automatically lower all the way down. 99% chance u accidentally held the unlock button long enough to initiate the feature,while u were in the house. Signal on those keys really accurate and strong

Or possibly sat on the keys with enough pressure to initiate the feature newer the key more sensitive it is
