When the internet drops, your guest still needs to get in

Picture a guest pulling into a vacation rental at 11 p.m., kids asleep in the backseat, punching in a door code that never syncs. The lock's been offline for hours — spotty Wi-Fi, a router reboot, whatever the cause — and the PIN generated by the reservation system never made it to the device. Now they're standing on a dark porch, calling a number nobody's answering yet.

It's one of the more common support calls behind vacation rental access control: the PIN worked on paper, but the lock never got the message. RemoteLock's backup PINs exist for exactly this moment — a quiet safety net that's already in place long before anything goes wrong.

A pool of PINs, waiting in reserve

Every supported smart lock can hold a small pool of backup PINs — two by default, adjustable up to five — synced directly to the device while it's still online. They sit there unused and invisible, even to the property manager, until a normal PIN fails to reach the lock. On locks that communicate over Bluetooth rather than Wi-Fi, that pool matters even more, since those devices are often installed in spots with the least reliable connectivity to begin with.

That's the part worth remembering: backup PINs have to be turned on and synced ahead of time. There's no flipping them on once the connection is already down. A property manager sets this up under account settings, selects the devices or locations, and RemoteLock handles the syncing in the background from there. It's one more reason choosing the right lock for a property up front pays off later.

When a sync fails

If a guest's PIN doesn't make it to an offline lock, RemoteLock flags the failure, and a new option appears on that guest's record: assign backup PIN. Clicking it pulls one of the pre-loaded codes out of reserve and attaches it to the guest.

From there, it works immediately, with none of the usual start and end time restrictions. If the lock's connection comes back before the reservation ends, that PIN is supposed to pick up the guest's original schedule automatically. If the lock never reconnects, the PIN keeps working until someone physically visits it and removes it — not unlike handing a spare key to a dog walker. It's practical, but it's not something to leave unmanaged.

Not the same as a ReadyPIN

For locks that support it, RemoteLock's time-bound ReadyPINs are usually the better first choice — they start and stop exactly on schedule, with no manual cleanup required. Backup PINs step in where that isn't an option, or as the last resort when even that process fails. The tradeoff is worth knowing upfront: backup PINs don't expire on their own, so someone still needs to close the loop once the guest moves on.

Build it in before you need it

Connectivity issues rarely show up at a convenient time — often not during a quiet stretch, but in the middle of a high-turnover weekend. That's especially true for operators running more properties with a smaller team, where there's no one nearby to swing by and check a router. Portfolios built around remote, staff-light operations are exactly where a pre-loaded pool of backup PINs earns its keep.

Setting it up takes a few minutes per device — and those are minutes better spent before a lock goes dark, not after.
