Seems like a newbie problem, key won't come out of key fob

I've been a Prius owner for a long time, but this is a ground zero, newbie-sounding problem. Can't get the mechanical key out of my key fob. I press the "Push" button as hard as I can, but the key will not slide out. I'm not a weak person, so I'm wondering if there's some trick to this.

I've tried this on both key fobs, can't get the key out of either. I've replaced the battery on the 2005 Prius key fobs that I had several times over the 14 years that I had that car, no problem. It had a much easier releasing mechanism for the key, though. This one, a 2015 Prius v, just will not allow me to remove the mechanical key.

So are you supposed to press the "Push" button in some particular way, or is there some release for the key that I'm not aware of. I need to replace the battery in one of my key fobs, so this is really frustrating.

Thanks!

 

Never mind, found that if I pressed the button at its lower end, the key finally released. Seems like that might be noted somewhere.

Tough being a newbie after 17 years of Prius ownership *smile*.
