Turning off the beeping tone when sitting in and hanging out

[Christopher Given Mead]

What's the best way to turn off or block the door open sensor on drivers side door. For example if you are just hanging out in your car (like me alot) and don't want to put up with unending annoyance of the chiming tone?

So you like to sit in the car with the door open? Is your ignition key turned off and pulled out, at least halfway?
