WiiKey Wired Installation
You can use wires to install the chip if you like this type of installation better. Here you can see the connecting spots better, so re-soldering would be easier if you didn't get it right the first time. With wired installation it would be a lot easier to remove the chip - not that it is needed, but who knows.

Buy WiiKey from a trusted retailer

Wii Key size compared to a 50 dollar bill.
P.S. The latest chip from the WiiKey Team is called DriveKey - and it is a lot easier to install like a passthrough on the data cable.
