I towed a 2008 Wrangler Sahara thousands of miles. It had a steering lock, and we had to leave the key on one click and lift the white fuse in the under hood fuse box. Never disconnected anything. Late, I disabled the steering lock and from then on removed the key, put in Neutral, and that's it. No problems.
I just bought a 2012 Wrangler Sahara. We just completed a 6 week 6000+ mile trip towing it. No steering lock, never left the key in or pulled a fuse, no problems. Very easy and reliable.
