How do i access my online garage in story mode?

Grand Theft Auto Online is a separate online multiplayer component of Grand Theft Auto V. It allows players to explore the open world of San Andreas with up to 30 other players and includes features such as personal garages where vehicles can be stored. The story mode of GTA V, which is the single-player campaign, does not include an online garage; it has its own vehicle storage locations that are accessed differently. Therefore, if you want to use the online garage you must be logged into GTA Online, not the story mode. Once in GTA Online, you can visit your personal garage by traveling to its in‑world location and interacting with the garage entrance.
