Most users ignore the interior DIP switches, but the manual details their power. To access them, remove the interior body cover.
| Switch # | Function (Up = On) | Use Case | | :--- | :--- | :--- | | 1 | Enable Random Number (Security) | Prevents smudge attacks by forcing you to press random numbers before your PIN. | | 2 | Dual Authentication Mode | Requires BOTH a fingerprint AND a PIN to open. | | 3 | Silent Mode | Disables all beeping (key for light sleepers). | | 4 | Vacation Mode | Disables all user codes except Master PIN. |
How to change: Flip the switches with the door OPEN to avoid locking yourself out. You do not need to remove batteries; changes take effect immediately.
When you first power up the V20 (after inserting batteries), the system will force you to create a Master PIN. This is the most important code.
| Action | Key sequence |
|--------|---------------|
| Enter Master mode | # MasterPIN # |
| Add fingerprint | 1 → 1 → slot → scan 4x |
| Add PIN code | 1 → 2 → slot → code → # |
| Delete user | 3 → 1 → slot → # |
| Change Master PIN | 2 → new PIN → # (repeat) |
| Enable auto-lock | 8 → 0 → 1 → # |
| Mute | 9 → 0 → 1 → # |
Final note: If your Gateman V20 has a physical key override slot under a flip cover on the front, always test the mechanical key once a year – some lock cylinders can seize if never used.
For exact programming codes, check the sticker inside the battery cover – many V20 variants have a simplified chart printed there.
