Yes. Two YouTube scheduled streams can use the same custom stream key at different times: create or choose a reusable key, associate it with each event, then select the intended event when it is time to broadcast.
The distinction is between sequential broadcasts and multiple configured entries that may compete through auto-start. YouTube documents custom-key reuse; a historical support report describes a conflict in a particular overlapping setup, not a universal ban on reuse.
Short answer: reuse at different times
A stream key identifies the feed your encoder sends to YouTube. YouTube describes it as being like a password and address for the stream, so treat it as confidential. The key does not, by itself, decide which scheduled event you mean: in Live Control Room, you also need to associate the key with the intended event and select that event when you start broadcasting.
For broadcasts that happen one after another, reusing a custom key is supported. YouTube Help says, “To reuse the same stream key, create a custom stream key.” Its scheduling workflow also lets you reuse a previous stream's settings, including its key. See YouTube's stream settings and key guidance and the scheduling guide.
That does not mean every arrangement of event records and auto-start settings will behave as you intend. If two configured entries might become active at once, treat that as a separate configuration question. A TeamYouTube community response from 2020 described a conflict in one such situation and advised using different keys for the entries involved. It is useful as a caution, not proof that current YouTube Studio always blocks overlapping entries or that sequential reuse is unsafe.
The practical answer is straightforward: for a morning devotional programme and an evening replay, you can use one reusable custom key if the first broadcast has ended before the second starts. Keep the scheduled event association clear, confirm the correct preview and avoid assuming that a key alone selects the right event.
Create or choose a reusable custom stream key
In YouTube Studio, open Live Control Room and go to the Stream tab. Open the stream-key menu, then either choose an existing custom key you control or create a new custom key. Give it a recognisable label, such as “Evening music encoder”, so that you can distinguish it from any keys you use for other channel workflows.
Choose settings that match the encoder or streaming application you actually use. Do not change a key's configuration simply because a second event is scheduled; the question here is which key is associated with an event, not whether the broadcast content or encoder settings should change. If your setup uses OBS, for example, the OBS setup guide for a 24/7 Krishna bhajan stream can help with the separate task of configuring the encoder.
The key is sensitive. Do not put it in a public document, screenshot, chat, or a stream description. Anyone with access to it may be able to send a feed to the channel. If you suspect it has been exposed, use YouTube's reset workflow in Live Control Room and update the encoder with the replacement key. Resetting a key can interrupt a running workflow until the sender uses the new value, so plan the change rather than making it casually during a live broadcast.
A custom key is useful because it gives you a stable value to enter in the encoder, while the event remains a distinct scheduled item. YouTube's reviewed guidance does not give a numeric maximum for how many scheduled stream records can share one custom key, so do not plan around an assumed limit. If you need to organise several programmes, name the keys and events in a way that makes their relationship visible rather than multiplying keys without a reason.
Associate the key with each scheduled broadcast
To create an event, open Live Control Room and use Manage to schedule a stream. When setting up an additional broadcast, YouTube offers the option to reuse settings from an earlier stream. Those settings include the stream key, but they may also include other event details. Review the title, description, visibility, schedule and other metadata instead of assuming that only the key was copied.
You can also choose the custom key directly for the new event, where the Studio interface offers that selection. The essential point is that each scheduled event needs its own correct event details, and the intended reusable key must be associated with it. A reused key does not turn two event records into one event, nor does scheduling the later item automatically prove that the encoder will send to that event.
A simple working record can prevent a common handover mistake. Note the programme name, scheduled start, event link, key label and who is responsible for starting the encoder. Do not include the actual key in a broadly shared schedule. For a small channel where the same person handles everything, a private checklist beside the daily timetable may be enough. For a team, keep access to the key limited and make the event link easy to verify.
If you are scheduling a repeating channel, decide whether you want each broadcast to have a separate event page or are using a continuing live setup. The stream-key question does not answer that editorial or channel-management decision. For a long-running playlist, compare the event workflow with the distinct always-on playlist approach; the key can be reusable in either case, but the way viewers find the broadcast and the way you manage its event are different.
Select and start the intended event
At broadcast time, check the event list in Live Control Room and open the scheduled event you mean to run. Then send the feed from the encoder using the YouTube stream URL and the key associated with that event. If more than one event is scheduled around the same time, do not rely on the event title shown in a calendar notification alone. Confirm the event in Studio before starting, especially if a previous event was duplicated using Reuse settings.
YouTube's live workflow includes a preview step. Wait for the incoming feed to appear in the intended event's Live Control Room preview and check that it is the right video and audio before you go live. This gives you a chance to spot a wrong event association, stale encoder scene or unexpected source while the broadcast is not yet visible as the event you meant to publish. YouTube's guidance on streaming with an encoder recommends setting up the encoder at least two hours ahead, starting it at least 15 minutes before the event, and checking the preview.
Those are YouTube's preparation recommendations, not a guarantee that a particular network, encoder or scheduled event will be ready on time. Build a little margin into your own routine: confirm the selected event, start the feed, review the preview and only then take the final go-live action. For a local news loop, this also gives you a moment to make sure that the correct bulletin is being sent; for a bhajan or study channel, it is a chance to verify that the right programme and sound are in the feed.
If you are using a computer-based encoder, the same key may remain saved for both events. The operator still needs to select the correct event in Live Control Room. The key is a credential for sending a feed; it is not a reliable substitute for checking what event is currently open. If a stream appears in the wrong event or no preview appears, stop and check the selected event, key association and encoder output before trying random settings changes.
Understand the overlapping-entry auto-start caution
Sequential reuse and overlap are different cases. With sequential use, one scheduled broadcast finishes and a later one uses the same custom key. With an overlapping configuration, more than one stream entry may be set up around the same key with auto-start enabled, and the system may not associate an incoming feed with the entry you expected.
A TeamYouTube response dated 11 August 2020 described a conflict involving multiple entries using the same key with auto-start and advised using different keys for those entries. Because that account is historical and specific, it should not be inflated into a current universal rule. YouTube's current documentation supports custom-key reuse, and the reviewed guidance does not state that every pair of overlapping event records sharing a key will fail.
A sensible precaution is to inspect the entries if Studio indicates that multiple streams are using the same key with auto-start enabled. If the entries could be active concurrently, use distinct keys for the entries that need to operate independently, or adjust the configuration so they are not competing. If the broadcasts are at different times, schedule and run them sequentially, and verify the selected event each time.
The trade-off is operational simplicity versus separation. One custom key is easier to maintain across sequential broadcasts. Separate keys give you a clearer boundary when different events or operators may send feeds independently, but they add another credential to store and update safely. For a channel where one person runs a morning and evening programme, a shared custom key may be the tidier arrangement; for separately managed overlapping shows, separate keys can make mistakes easier to diagnose.
Do not infer more than the evidence supports. The historical report is a reason to investigate an overlap, not a reason to abandon sequential reuse. Nor should you assume that auto-start will resolve every event choice for you. If the Studio interface warns about competing entries, heed the warning and simplify the configuration before relying on it overnight.
Check the active event before sending the feed
Before every broadcast, verify three separate things: the event selected in Live Control Room, the key associated with that event, and the feed shown in its preview. These checks catch different problems. A correct key can still be paired with the wrong event; the correct event can receive an unintended encoder source; and a preview can reveal that a stored encoder profile is not sending what you expected.
If the incoming feed does not appear, check the encoder's selected YouTube URL and key against the intended event. Confirm that the key has not been reset since the encoder was last configured. If it was reset, replace the old value in the sender and test again. If you are changing settings on a machine used for several channels or events, check the active profile as well as the stream key; a previously saved profile can send video to a different destination than the one you are currently viewing.
For a channel that must continue overnight, think about who will notice if the event is wrong or the feed stops. Monitoring from another device can make a quiet failure visible sooner; the guide to monitoring a 24/7 Indian music stream from another device covers that separate operational task. Monitoring does not replace checking the event before starting, but it gives you another way to notice a problem after the broadcast begins.
If your usual sender is a computer at the premises, an always-on workflow can also depend on that computer and its power or network connection. StreamNeo can remove the need to leave your own computer running for an uploaded-video broadcast, which addresses that specific overnight-running burden; it does not change YouTube's event selection or key-handling steps. Whichever workflow you use, retain access to the event in Live Control Room and check that the broadcast is associated with the event you intended.

FAQ
Can two YouTube scheduled streams use the same stream key at different times?
Yes. YouTube documents custom stream keys for reuse and lets you reuse settings from a previous stream when scheduling. Associate the key with each event and select the intended event when you are ready to send the feed.
Does reusing a stream key mean I can skip selecting the event?
No. The key lets YouTube receive the encoder's feed, but you should still open the intended scheduled event in Live Control Room and check its preview. Confirming the event avoids relying on the key to identify which scheduled broadcast you meant.
Should I use separate keys if auto-start is enabled?
Consider separate keys if multiple configured entries could compete or be active at the same time. A TeamYouTube response in 2020 described a conflict in a particular overlapping auto-start setup, but that historical report is not a universal current restriction on sequential reuse.
What should I do if I think someone has seen my key?
Reset the key in YouTube Live Control Room, then update the encoder or other sender with the replacement. Treat the old value as compromised and verify the next event's preview before taking it live.
