Gone in 61 seconds.

The keys were left near the front door.

@it4sec But wait... how can you drive out of range of the key? My car stops when you do this.
@BubblegumYeti @it4sec Depends on the model I think. Some will sound an alarm inside the car, but allow you to drive a (shortish) distance (to avoid potential crashes if say your kid throws the keys out of the window while on the highway).
