Lol, I've left my keys on this bike twice already once in pannier and once in the seat lock, hopefully I want learn the hard way I'm up to 5 keys now with gas tank, brake,helmet, cover, panniers and bike key.Yeah locking WAS annoying but I don't mind anymore and as you said always secured AND you got your keys! I think it helps you control keys. Not sure how many times my buddy on his beemer would say at our next stop.... Look at this, he left/forgot his key in one of his luggage/panniers lock.😂 But he hasn't lost, lost them, yet.
