Just remove it and store using some other type of lock, such as padlock around the topstrap or better yet - in a vault. The hole is good for that occasional drop of lube - don't overdo the lube. The key lock is not designed to be locked when it is carried or ready for use anyway, so if you use an alternate method of securing it and can explain it, I cannot see the difference. I imagine there are many who will argue with me on this point, but everyone is entitled to an opinion.
