If you use RemoteLock for door access, you can drop a guest's door code directly into your automated SMS messages. The code drops in automatically when the automation runs — no manual lookup, no copy-paste.
You'll need:
RemoteLock connected to your Hello Hotel organization. The Door Code variable only shows up in the variable picker for properties with an active RemoteLock integration.
An automation that sends an SMS — typically a check-in automation that fires on a scheduled time or a reservation event.
Open the automation in the workflow builder.
Click into the SMS message body where you want the door code to appear.
Open the variable picker.
Under Reservation, select Door Code.
The variable {{reservation.doorCode}} gets inserted at your cursor. When the automation runs, it's replaced with the actual code for that guest.
Hi {{guest.firstName|there}}, welcome to The Timberline! Your room is {{reservation.spaceNumber}} and your door code is {{reservation.doorCode}}. The code is active from {{reservation.checkInDateTime}} to {{reservation.checkOutDateTime}}.
Sometimes RemoteLock doesn't generate a door code for a reservation — for example, if a webhook is missed or the integration runs into a hiccup. The automation handles this gracefully: the message sends with a blank space where the code would have gone, instead of failing entirely.
Your team will need to follow up manually for those guests. Sending with a blank field is rarely ideal for guest experience, so it's worth a quick scan of any reservations that don't have a code generated by the morning of check-in.
In addition to pushing codes outward, Hello Hotel syncs door access events inward from RemoteLock. When a guest uses their code to unlock the door, that event flows back into Hello Hotel so your team has visibility into when guests actually arrive.
Access events are scoped to the linked reservation — meaning the event surfaces against the guest staying in that room, not as a generic "someone unlocked door X" entry. The room name is resolved from your RemoteLock device list so the event reads naturally (e.g., "King Room unlocked at 3:42 PM" rather than a device ID). If a code is used outside of a guest stay, the event still flows in but isn't tied to a guest reservation.
Use the picker, not direct typing. The Door Code variable only shows up if RemoteLock is connected to your organization. If you don't see it in the picker, that's the first thing to check.
Pair it with check-in date and time. Door codes are typically time-scoped to the guest's stay. Including check-in and check-out times in the same message helps guests understand when their code is active.
Test with Send Test before activating. The Send Test button on any Send SMS action lets you preview the message with sample data, so you can see how the door code lands.
