Key Revocation at Checkout

When checkout occurs (manual or automatic), your entry key is automatically revoked.

How Revocation Works

  • Manual checkout: Your entry key is revoked when you complete the checkout process
  • Auto-checkout: When the plan's usage period ends and auto-checkout occurs, your entry key is revoked simultaneously
  • Quick Mode deactivation: If the facility owner deactivates the URL, your key is also automatically revoked

What Happens with a Revoked Key

A revoked key will not unlock the door. If you need a new key, you must check in again.

Additional FAQ

Q: Will my key stop working after checkout?

A: Yes, your key is automatically revoked at checkout. This applies to both manual checkout and auto-checkout.

Q: Do I get an exit key if I'm auto-checked out?

A: Auto-checkout does not automatically issue an exit key. If you need an exit key, please contact the facility.
