I have to admit that I haven't had the occasion to try because I make my living a different way but I think that I could do it. The real point is that, once you get past the cheesiest of locks, you are engaged in a high tech game of one-ups-man-ship with the thieves. Ultimately, that's a game that you will always lose. If you leave your bike parked in the same place day after day it gives the thief the opportunity to figure out what he needs to bring with him to steal it and when's the best time to do it.
