There are a total of 36 lockers in Splatoon 3: Side Order, and each one holds a reward that players can claim. More specifically, fans can find new Palettes, Prlz, and more inside the Side Order lockers, though they cannot open all of those containers straightway. Indeed, players must use keys in order to open the lockers in Splatoon 3: Side Order, and this guide contains details on how to earn those items and elaborates upon exactly what can be found inside the associated containers.
While it is definitely not mandatory that players open all the lockers in the DLC, doing so is a requirement for earning every badge in Splatoon 3: Side Order .

Lockers that contain new Palettes pulsate as a player gets close to unlocking them. Considering how important new weapons are to the process of opening lockers, something that is further detailed in the following section, this visual cue may serve to keep players excited to continue clearing Floors in Splatoon 3: Side Order with the Palettes that they have.
Splatoon 3: Side Order - How to Get Locker Keys
While players will receive their first three locker keys upon completion of the tutorial run, they will need to focus on working through standard runs with a variety of weapons if they want to earn more of them. Indeed, a locker key is awarded at the ends of Floors 10, 20, and 30 when those Floors are completed with a Palette for the first time. This means that fans can earn up to three locker keys per weapon in Splatoon 3: Side Order, and they will receive more Palettes to take into the Spire of Order as they use their keys to open more lockers.
To note, while fans may initially find it quite difficult to earn locker keys, things should become easier as they put more time into the DLC. This is due to the fact that players are able to make permanent upgrades between runs, which will make reaching and clearing Floors 10, 20, and 30 more feasible. For full clarity, those permanent upgrades are made with Prlz in Splatoon 3: Side Order, a currency that is awarded at the end of every run.
