What Sifely actually is
Sifely makes Bluetooth and WiFi smart locks aimed at short-term rental operators who want automated guest access without ongoing subscription fees. The Auto Booking Code feature pulls reservation data from connected platforms and generates time-limited passcodes, removing a common manual step from the check-in workflow. Locks ship with five unlock methods — fingerprint, code, fob, smartphone, and physical key — so guests have fallback options if one method fails. Remote management requires a separate WiFi gateway purchase.
Core features
- Auto Booking Code generates time-limited passcodes from PMS reservations
- Five unlock methods: fingerprint, code, fob, smartphone, and physical key
- Auto-lock engages after a configurable delay to prevent unlocked doors
- Reversible handle fits left- and right-hand door configurations
- WiFi gateway available for remote lock management
Pros
- Auto-generated guest codes eliminate manual access management
- Multiple unlock methods provide redundancy against guest lockouts
- Auto-lock prevents guests from leaving doors unsecured
Cons
- Touchpad responsiveness is inconsistent — works ~90% of the time per user reports
- Remote access requires purchasing a separate WiFi gateway
- Fingerprint scanner failures reported by multiple users
