| Message | Anyone can take a screwdriver/chisel, use the notch as a chisel point, and just break them off.  The notch is there to help with the magnet with torque. A dremel at low speeds can easily take it off as well, less noise. Since the grooves are OUTSIDE instead of INSIDE the housing, I can use a pair of vice grips/needle noses and just grip them off! Without a tilt/shock sensor, while youre at your partners house, I take off the lock with ease and take the wheels again. Its just for bling factor, nothing really differentiates these from McGard security locks/comparable companies.  In fact, they're worse if you think about it... even the website states, the sheer design of the grooves allows for only ~ a hundred possibilities.  If youre at a huge Silvia meet with a bunch of guys who ordered this set, chances are one of you has the same key! LOL
