At the Dartmoor level in Hitman 3, you will need to acquire as many keys as possible to bypass Thornbridge Manor and gather the necessary clues. Unfortunately, they are all well-hidden.

In our guide, we will tell you where to find all the room keys in Dartmoor in Hitman 3. We will also tell you about a master key that opens all doors. Let's get started!

Location of the Greenhouse Keys

It's challenging to enter the greenhouse, and on your first attempt, you will try hard to get inside. However, if you genuinely want to open the door to the greenhouse without using a lockpick or crowbar, you can take the key from Emma.

This means you'll have to knock her out first (make sure to do it from a distance). For example, take a baseball and throw it at her head, then wait for her to recover. Now you can approach her and take your key.

Where to Find the Fernsby's Office Key

Fernsby's office is crucial - there are clues necessary if you want to achieve the secret ending of the Dartmoor mission. However, just like with the greenhouse key, you can silently obtain the key to Fernsby's cabinet by subduing him and then picking it up (to avoid being spotted).

Location of the Bedroom Keys

Each bedroom in Thornbridge Manor has its own key. You can obtain it by subduing or killing the occupant. Remember, you need to do it stealthily; otherwise, the mansion's guards will open fire immediately. Here is who carries the keys:

• Emma and Gregory's Room - the keys are with Gregory.
• Rebecca's Room - the keys are with Rebecca.
• Alexa Carlisle's Bedroom is freely accessible as she is in charge of cleaning.

Location of the Master Key

Fortunately for us, there is a master key in Thornbridge Manor that opens all locked doors inside (although it still won't lead you to the greenhouse). To obtain it, you'll have to infiltrate Fernsby's office and take the key from the shelf on the right side of the entrance.
