d100 - Where Is The Key For This Locked Door?

Locked Doors or Containers are a time-honored obstacle to exploration and discovery. They present an opportunity for the clever Thief to fiddle with their tools to flex their percentiles, the Fighter to muscle things open with a sturdy d6, or the Magic User to unleash a mighty Knock. If only there were another way?

The presence of a Lock implies the existence of a Key. Here are a Hundred places where that pesky unlocker might live. Much like my previous posts on Secret or Stuck Doors, some imply a puzzle or a skosh of Set Dressing as well. Some of the particularly tricky ones might be worthy of rewarding the Players with a passe-partout.
