-While adding a new repeatable job with same key but different repeat options, you will override your previous record.
-{% endhint %}
+#### Updating repeatable job's options
+
+Using custom keys allows to update existing repeatable jobs by just adding a new repeatable job using the same key, so for instance, if we wanted to change the repetition interval of the previous job that used the key "eagle" we could just a new job like this:
+
+```typescript
+// Repeat job every 25 seconds instead of 10 seconds
+await myQueue.add(
+  'bird',
+  { color: 'turquoise' },
+  {
+    repeat: {
+      every: 25_000,
+      key: 'eagle',
+    },
+  },
+);
+```
+
+The code above will not create a new repeatable meta job, it will just update the existing meta job's interval from 10 seconds to 25 seconds. Note that if there is already a job delayed for running withinthe 10 seconds it will not be affected by this change.
