Log into your account, select My Keys. Click + NEW and complete the form. You can give access to all your keys or just a single set. You can set the access as Scheduled where the guest can only pickup the keys during the dates specified or Ongoing where the guest has access until you revoke it. You can also add comments to the reservation which are visible to the guest when they log into their Keycafe account and select the keys.
Your guest will receive an email notification with a secure link to set up their access credentials. If they already have a Keycafe account the access will appear in their account and they can use their existing credentials. Once they set their mobile number and PIN, they can pick up your keys at the Keycafe location.
