Deltarune: How to Find All Keys in Round One (Chapter 3)

Deltarune Chapter 3 features a unique segment where you need to find keys to progress, in Ant Tenna's TV Time Game Show. While you generally only need three keys to open the Pyramid gate and move forward in the story, there are actually four keys available in the main game show segment (five if you’ve completed Chapter 3 at least once). This guide covers the locations of all five keys in Chapter 3 of Deltarune, so that you don’t miss a single one.

Deltarune Chapter 3 - All Key Locations

Here is how you can find all five keys in Chapter 3:

Deltarune Chapter 3 - Key #1 Location

The first key is the easiest one to get. It's available for purchase in the shop near the starting area for 250 points. Buying it is a net positive for your overall score in the game show.

Deltarune Chapter 3 - Key #2 Location

The next key is commonly called the Sphinx Key. To get this key, you need to collect two "Q" items by completing quizzes from Tenna.

Once you have both of the Q items, bring them to the Sphinx in the top-right corner of the map. Then, answer the quiz questions. The answers are "Body," "Pippins," and "Sword Magician". The Sphinx will then open a path to the left, leading to the second key. You'll probably have walked by this key earlier in the minigame.

To get your hands on this key, you must solve a puzzle to unlock the Power Croissant for Susie in Deltarune, which gives her the ability to grab and throw pots.

To find the third key, you need to rescue Lancer. To do this, follow the steps below:

Head to the top-left corner of the map where Lancer is trapped in a cactus.
Step on the red button, and Susie will toss Ralsei to free Lancer.
Then, guide Lancer to the oasis spring located one screen down and left from where you rescued him.
Lancer will then dig up the key for you from the L spot. This will also unlock a boss fight in a different part of the map.

Deltarune Chapter 3 - Key #4 Location

To find the fourth key, head to the cactus field. One of the Pippins will give you a clue: "The cactus that lived upstairs loves you." This refers to a specific cactus that will blush when you approach it. Simply push this blushing cactus aside, and the key will be hiding underneath.

Deltarune Chapter 3 - Key #5 Location

The fifth key is hidden in the bottom-left corner of the first board's map within the game show. To reach it, you enter an area where Susie, from off-screen, starts throwing numerous bombs at your party. You need to carefully move through the explosions without taking too much damage.
