Key for T-Bird Power Flash?

[webdeck]

After many months, I've finally gotten around to putting my Power Flash into a cabinet ("amazing pachinko cabinet" from slot-pachinko.com) and hanging it on the wall. The down side is, I have to lift the heavy cabinet off of the french cleat if I ever need to access the back of it, since I don't have a key for the lock. Does anyone have a key for this model? The front of the lock is labeled "N". I searched and saw other posts that described removing the lock and taking it to a locksmith to have a key made, but I couldn't figure out how to do that - do I need to remove the entire latching mechanism to get the lock out?

Obligatory photo - my wife surprised me for fathers day by staining the cabinet to match my office - it looks really nice!

Thanks,
