Aelement is Salto's design-forward hotel lock and the standard sibling to Aelement Fusion. It splits the lock into a slim reader escutcheon and a separate battery pack, so the guest-side hardware stays minimal and the styling disappears into the door. It runs the full Salto credential stack (BLE and NFC mobile keys, MIFARE and DESFire RFID, PIN), fits ANSI standard mortise prep, supports brand mobile-key programs, and offers mechanical or electronic push-button privacy. Choose Aelement when you want the design look on a Salto Space property; step up to Aelement Fusion when the single-piece fused escutcheon and top-tier finishes are part of the room design language.

Things to think about

Aelement vs. Aelement Fusion

Both are the design line and share the credential stack, PMS integration, and ANSI mortise prep. Aelement uses a slim reader with a separate battery pack; Fusion fuses the reader and electronics into one premium escutcheon with the top-tier finishes. Pick Aelement for the design look at a lower per-door cost, Fusion when the single-piece escutcheon is part of the room design.

Indoor, ANSI mortise prep

Aelement is an indoor hotel lock built for ANSI mortise prep. Confirm the door prep and that the install is interior before specifying it across a floor.

Aelement: frequently asked

  • Is the Salto XS4 One good for high-traffic hotel doors?

    Yes. XS4 One is a full ANSI mortise lock built for high-cycle guest-room and corridor doors. It runs roughly 60,000 openings per battery set, typically 24 to 36 months of service at hotel traffic. For very high-traffic main entrances it remains the right Salto choice over the compact XS4 Mini.

  • What is the difference between XS4 One and XS4 Mini?

    They share the same credential stack (BLE, NFC, RFID, PIN), the same PMS integrations, and the same brand mobile-key compliance. XS4 One is a full mortise lock suited to high-traffic doors; XS4 Mini is a compact, indoor, lower-cost escutcheon best for value-tier and extended-stay rooms. When brand standards are silent and the door is high-traffic, XS4 One is the safer call.

  • Does XS4 One support Apple Wallet keys?

    Yes. With 2024 firmware, XS4 One supports Apple Wallet room keys alongside BLE and NFC mobile credentials. RevKey confirms the exact firmware and brand mobile-key program your property is certified to before the order ships.

  • Can XS4 One be retrofitted onto existing doors?

    On most doors with ANSI standard mortise prep, XS4 One drops in without millwork changes. If the door prep cannot be modified (occupied units, historic doors, custom millwork), a Neo cylinder swap is usually the better retrofit even though XS4 One is the stronger lock.
