I love this site. It's good for us dummies. Mine popped open once when I went across an uneven road that flexed the trike in every direction. The button was hard to push and had to have the key inserted to pull it out. The dealer said not to worry, that it would free up over time. After reading here I had a "duh" moment. I found some dry lube and squirted some on and in the latch. No more hard to push. Button pops out all the way. Can just push it closed instead of slamming it and hoping it latched.
Thanks guys for helping this dummy out. I'm sure I will be gleaning more info from you.
