Last year, when I bought my “MiG”, one of the very first purchases I made was the Givi Monokey V46 topcase to address my storage needs for commuting. The case fits my helmet and jacket, but when touring I found myself wanting some additional room for my stuff. This is why in the beginning of this season I also purchased Givi N21 sidecases. I don’t carry them often, but when I do, I end up carrying two identical-looking keys for my luggage, which sometimes causes confusion.
As it happens, Givi sells a 3-case lock set with 6(!) Keys included. It’s only about $20, so I eventually pulled the trigger and got the keys shipped to me by Twisted Throttle.
The locks look almost identical to the ones installed in sidecases – the only exception is that the weather cover on the key hole is red in color as opposed to the usual chrome of the original locks. I had no problem replacing the locks: open the case, remove the retaining rig from the inside of the lock, replace the lock, and replace the retaining ring (the lock set comes with 3 retaining rings, in case if you lose the one you just removed)
The topcase turned out to be a little more difficult. The topcase lock is about 13.5 mm in diameter, while sidecase lock is about 12.4.
Luckily, a sidecases lock can still be used inside in topcase ( it wouldn’t work the other way), but it introduces some “play” and makes the lock feel less solid.
Additionally the base of the lock cylinder (near the key side) has a different pattern of protrusions ( they serve as stops for the cylinder when it rotates) which makes it so that the sidecase lock cannot be fully set in place which, in turn, translates in the cylinder not coming out enough on the other side of the lock assembly. This means that the face of the rotating latch had to have about 0.5 – 0.8 mm filed off before I could put the retaining ring back in its place.
Overall, I am glad I was able to fix the incompatibility of the new locks with the topcase, bit it would be nicer if the 3-case lock set came with compatible locks.
