Clear a Matter lock credential
Use this action to remove a single credential, such as a PIN code or an RFID tag, from a Matter lock. A common use is to revoke one credential while keeping the user and their other credentials in place.
Using this action from the user interface
If you prefer building automations and scripts visually, Home Assistant walks you through this action step by step. You pick what to target, tweak a few options, and save. No YAML knowledge required.
To clear a lock credential from an automation or a script:
- Go to Settings > Automations & scenes.
- Open an existing automation or script, or select Create automation > Create new automation.
- If you’re setting up a new automation, add a trigger in the When section. Scripts don’t need a trigger. They run when something else calls them.
- In the Then do section, select Add action.
- Select what you want to control. Under By target (see Targets), select the lock you want to manage.
- From the actions shown for that target, select Clear a Matter lock credential.

matter.living_room. - Device: every matter entity that belongs to a device.
- Area: every matter entity in a room or area.
- Floor: every matter entity on a floor.
