Key Lockers 
(also known as "Key Capsules") are Capsule-like items that can be used to store only Portal Keys 
. Each Key Locker can store up to one hundred (100) Portal Keys each, and any Portal Keys inside do not count toward the Inventory Cap. Just like Capsules 
, they have a unique identifier, and can be renamed for sorting. This means an Agent can hold up to six hundred (600) Portal Keys outside their inventory. The Key Locker is the only item in Ingress where items placed inside do not count toward the Inventory Cap.
There are six purchasable Key Lockers : a white, yellow, red, green, blue and Onyx Key Locker . Each Key Locker is purchasable for 
3 700 CMU each. An Agent can also purchase all six at once in a discounted pack for 18 000 CMU, saving 4 200 CMU.
A special Key Locker which was red with black edges was given out during the fifth anniversary of Ingress and can not be bought[1]. During the #FieldArt Challenge, a new Key Locker called "Onyx Key Locker" was introduced for purchase in the store for 3 700 CMU for all Agents that did not already own six Key Lockers . After feedback from Agents, Niantic added the Onyx Key Locker permanently to the store and raised the Cap from five to six.
Key Lockers cannot be recycled, dropped or shared, since it is a premium item. Agents can purchase the same coloured Key Locker multiple times, as long as the Agent does not already have six Key Lockers in their inventory. This means an Agent could buy six yellow Key Lockers .

Strategy
Even though the Key Locker is only limited to holding Portal Keys , it still can play a huge role in inventory management and storage, proving a high value for Agents.
- Agents who frequently plan Control Fields Δ can store Portal Keys in the Key Lockers until it is time to field.
- Agents can store unused Portal Keys inside Key Lockers , especially ones that serve as a memento.
- Agents can hide Portal Keys away to avoid throwing Links that will mess up a plan. (A Key Locker is not strictly necessary for this since regular Capsules also hide stored Portal Keys from the linking screen)
- Agents can also quickly store away Portal Keys to make space for more items when on a hacking spree.
- Agents can use the different coloured Key Lockers to better organize their Portal Keys .
