# Collection Lock

> Password-protect an entire collection, including products added to it later — a paid plan feature.

A **Collection lock** password-protects every product in a collection — including products you add to that collection after the lock is created. This is a **paid plan** feature.

## When to use a Collection lock

* You have a whole collection (like a new seasonal line, or a wholesale-only catalog) that shouldn't be purchasable until a specific date
* You keep adding new products to a collection over time and don't want to remember to lock each one individually
* You need to lock more products than a single [Product lock](/locking-your-store/product-lock) allows (20 max)

## Requirements

The collection you want to lock must already be **published to your Online Store**. Launch Day checks this when you create the lock and will ask you to publish it first if it isn't.

## Creating a Collection lock

Follow the steps in [Creating Your First Lock](/getting-started/creating-your-first-lock) and choose **Collection(s)** as the lock scope, then click **Select collection** to choose which one to lock.

<Warning>
  If a product in the collection is already locked by a different lock, that product stays under its original lock and isn't affected by this one — Launch Day will warn you if it detects an overlap when you pick the collection.
</Warning>

## Staying in sync automatically

Once a Collection lock is active, Launch Day keeps it in sync with your collection automatically:

* A product **added** to the collection later gets locked automatically, with no action needed from you
* A product **removed** from the collection gets unlocked automatically (unless it's still covered by a different lock)

You don't need to re-save the lock for these to take effect — Launch Day picks up collection membership changes on its own.

## What customers see

Every product in the locked collection shows Launch Day's lock screen instead of the normal product page — unless you've turned on [Hide Buy/Shop Buttons](/locking-your-store/customizing-the-lock-screen) instead.
