After searching the cellar during the **Anamnesis** quest in *Kingdom Come: Deliverance 2*, you will come across a locked door that blocks your progress. The next step is to find the cellar key, but there are no obvious clues indicating where it might be.
### Where to Find the Cellar Door Key
To find the key, your first step is to talk to **Zdenyek**, who can be found at the north end of the monastery grounds. During your conversation, bring up **Blazhena**. Zdenyek will reveal that he suspected Blazhena of stealing food, since only the two of them had keys to the pantry where the food was stored. He was even considering getting rid of her before she fell ill. He will ask you to promise not to share his suspicions with anyone.
Next, you need to speak with **Valerie**, the blonde maid nearby, and also examine Blazhena’s room, which she shares with Valerie. If you talk to Valerie first, she will hesitate to speak with Zdenyek nearby, so it’s better to check Blazhena’s room before returning to Valerie.
### Checking Blazhena’s Room
Head to the small building at the top of the courtyard. Enter the door on the back right and go upstairs. Blazhena’s bed is by the window, and if you check the chest at the foot of her bed, you will find a large amount of money — far too much for a maid. Nearby, you’ll find the pantry key resting on a shelf near the head of the bed.
After grabbing the key, return to Valerie. She will confess that she saw Zdenyek taking something from Blazhena’s chest and being harsh with her. Valerie also mentions a nearby cellar that Zdenyek visits. This location will then be marked on your map and is revealed to be the pantry.
### Investigating the Pantry
Head to the pantry and explore all three rooms thoroughly. Examine the wine barrels, tubs of water, crates, and other items in each room. Some areas may require lockpicking to gain entry.
After investigating, Henry will deduce that Zdenyek has been watering down the monastery wine. You can then confront him about this.
### Confronting Zdenyek
When confronted, Zdenyek will ask to speak with you privately in a nearby field. You can choose to accept or decline. It’s worth going with him if you want to obtain a weapon.
In the field, Zdenyek will try to attack you. Defeat him in combat, and once he submits, demand his axe. He will also give you the key to the cellar door — a key he took from Blazhena’s chest.
### Returning to the Cellar
With the key in hand, return to the main cellar where you discovered the secret door earlier. Use the key to unlock the door and continue your investigation.
