Running an Airbnb, long-term rental, or serviced apartment means one thing is certain: tenants come and go—but their access credentials shouldn’t stay behind.
Below is the fastest, safest way to wipe every trace of the previous occupant from your smart lock.
Follow the 10-second routine and you’ll never worry about “ghost” keys again.
The 10-Second Delete Routine (Works on 95 % of Our Locks)
- Wake the lock
Touch the keypad or press the *# key once. The voice/menu will say “Hello.” - Enter master mode
Type Master PIN + # + 9 (factory default is 123456#9—change it!).
You’ll hear “Menu mode.” - Choose user batch
Press 3 for “Delete user.”
Press 1 for “Delete by ID” (fastest) or 2 for “Delete all renters.” - Confirm in 1 tap
Press # again. The lock answers “Deleted successfully.”
All fingerprints, PINs, and temporary RFID cards linked to that slot vanish instantly.
Total elapsed time: ≈ 8–10 seconds.
Visual Quick-Guide
| Step | Key Press | Voice Prompt | What Happens |
|---|---|---|---|
| 1 | Touch keypad | “Hello” | Screen wakes |
| 2 | 123456#9 | “Menu mode” | Master verified |
| 3 | 3 → 2 | “Delete all renters?” | Select batch |
| 4 | # | “Deleted successfully” | Memory cleared |
Pro Tips for Landlords
- Always keep the Master PIN in your own password manager—never share it with tenants.
- Create numbered slots (e.g., 01–20) reserved for renters; cleaning them later is one-click.
- Enable “Auto-expire” when you issue a temporary code; the lock erases it at check-out time automatically.
- Once a quarter, export the audit log (Bluetooth or Wi-Fi models) to prove no unauthorized entries.
What If You Forgot the Master PIN?
- Open the back cover.
- Hold the RESET button for 5 s until the LED flashes red.
- Re-configure the lock from scratch (takes 2 min).
Note: This will delete every user, so re-add your own admin fingerprint first.
