Like the previous poster, I also keep it in my watch pocket in my jeans. I keep both the key and fob attached to a small ring. I used to keep them in my front pocket but sometimes they'd be uncomfortable on a ride. With them in my watch pocket I don't feel them at all. FWIW, some people call it a change pocket.

 

Merri1, Gorgeous trike. Love the color.

 

I'm a Moron...in the tour pack. There is a pouch in there fits perfect. Wait I'm a double Moron both fobs are in there!

That's good, the thief can have a spare key.

 

On the key ring with disc lock key and house key and in my pocket while riding.

 

I like that idea.
