Well, since I have a house with no garage, I just have a 6' Kryptonite cable lock that I use to lock the scoot to my back porch.
At work, I cable it to a huge metal light pole. Plus, I use the steering lock all the time.
The rest of the time, if I'm just out at the store or hanging out somewhere, I don't worry about locking it up. I just lock the steering. I only use the cable lock if it's parked for several hours, i.e.-at work or when I'm home sleeping.
