The Golden Key spawns on the ground, at random, in any of the Forest stages in Megabonk. It only shows up if you haven't unlocked the character Monke, since the key is part of what you need to free it and make it playable.
This article is not about the item name Key that you get from chests. That item gives you a 10-percent chance to open future Chests for free, and it has nothing to do with unlocking Monke.
To find the Golden Key in the Forest to release the Monke, walk around the map, covering as much ground as possible, while paying attention to items on the floor. The key can show up anywhere, anytime, on any of the Forest stages, and there's a chance it won't appear at all. Unfortunately, the Golden Key has no mini-map icon. If you can't find it, start a new run.

Once you see the Golden Key, approach it and interact with it to pick it up. Walking over it like you do with Powerups will not work. Then, look for a cage on the map and interact with it, and you will free Monke and gain the ability to purchase him with Silver in the Unlock screen after you complete your run. The cage will always spawn, as long as you haven't unlocked Monke yet.
I understand you're probably excited to test some of the best Monke builds in Megabonk and want to speed things up. But since there's no way to manipulate the Golden Key spawn or increase the odds of seeing it, the best method to get it is to naturally play the Forest map as you focus on other quests and progress through other unlocks. In my playthrough, I saw the Golden Key once in around five attempts.
You will eventually run into the Golden Key, and when you do, ignore everything else you were doing and rush to a cage to free Monke. If you feel comfortable playing in Forest tier 2, it's a good idea to do it to look for the Golden Key because this item also spawns on Stage 2, so you have higher chances of finding it on the same run.
