Practical notes on opening mechanical combination safe locks — written for the trade.
Scan 8,000 combinations (odd 5) or 64,000 combinations (odd 2.5). Press START and wait — the machine auto-dials, auto-tries, auto-detects when the lock opens. No intervention needed.
Closed-loop stepper motor with continuous position feedback — no step loss, high torque, smooth operation. Industrial driver with solid aluminum heat dissipation. Runs continuously for 12+ hours stably.
Smart detection mechanism based on mechanical load feedback of the closed-loop motor. When the lock lever releases, the system recognizes it instantly — stops, displays the correct combination. No external sensors needed, no signal drift.
Touchscreen displays the number being tried, realtime progress bar, scan direction and status. One-touch START/STOP. No laptop, phone or any additional connection needed.
Stable 24V DC power supply, no lithium battery. Industrial driver with active heat dissipation, motor operates at 30% of maximum capacity. 24-hour burn-in test before shipping.
No Wi-Fi, Bluetooth, SIM or lithium battery. Not restricted by international air shipping.
Not just opening safes in a lab — AutoDialer V4 was designed from 5 years of real-world field experience, solving exactly the problems locksmiths encounter on site.
Automatically saves the last 3 numbers to memory every minute. Power loss — plug back in, adjust S1 to the saved number, press RUN. The screen always displays chip temperature, run time and combinations scanned.
FAST — new safe, tight mechanism, turn fast at maximum. NORMAL — standard safe, balancing speed and reliability. SLOW Old safe, loose latch, turn slowly so the sensor catches precisely when the latch releases. Select on the screen before running.
Select direction of rotation (left or right) and step (5.0 / 2.5 / 2.0 / 1.5) completely independent on the screen. The safe opens whether it turns right or left. Large steps for speed, small steps for maximum precision. Supports both locks 3 discs and 4 discs.
Auto-rotate t5 corner every 5 seconds: scan direction + chip temperature — runtime + number of combos scanned — combination being tried. Monitor the entire progress without any operation.
Closed-loop motor continuously monitors the mechanical load. When the trigger releases and the lock opens, the system recognizes it instantly — the machine detects it immediately, stops, and displays the 3 combo numbers on the screen. No misses.
Stable 24V DC power supply, motor runs at 30% capacity, driver with solid aluminum heatsink. Operating temperature 40–45°C. Designed to run 12+ hours continuously — hand over the machine, go do other work, come back for the results.
AutoDialer V4 uses selected industrial-grade components — every part is chosen to ensure precision, durability, and reliability during continuous operation for many hours.
AutoDialer V4 scans in 3 phases from fast to high precision. Most safes will open during the initial fast scan phase — only the hardest cases proceed to the comprehensive scan phase.
The machine starts with 47 default combinations from popular manufacturers (~3 minutes), then scans odd 5 (8,000 combinations). Most safes — including safes set incorrectly or not compliant with standards — will open during this phase, in about 1 hour.
| Mode | First hour (75% safe) | Most safes open within | Suitable when |
|---|---|---|---|
| Slow | ~1.0 hour | ~9 hours | Old safe, loose lever, needs highest precision when sensor detects lever release. |
| NormalRECOMMENDED | ~0.9 hour | ~8 hours | Standard safe. Balances speed and reliability. Auto-selected on START. |
| Fast | ~0.8 hour | ~7 hours | New safe, tight mechanism. Demonstration, training, quick results. |
The unlocking times stated above are estimates based on internal testing with a 3-wheel mechanical combination lock under normal operating conditions, using the correct power supply (24 VDC, 5 A) and the recommended installation procedure. Actual times may vary depending on the lock manufacturer, model, internal tolerances, mechanical condition, dial alignment accuracy, and environmental conditions.
AutoDialer V4 can open even safes set with a combination incorrectly — includes numbers within the contact area. Since the machine scans almost the entire possible number range, opening time for these safes may be longer than usual — in return, the success rate remains very high.
Some safes — especially those with non-standard wheel patterns, high-security Group 2 locks, anti-manipulation mechanisms, or heavy internal wear — may require longer scanning time. Locks with electronic components, time-lock, dual-key mechanisms, or relockers are outside the support scope of AutoDialer V4.
The "100% success" commitment applies to standard 3-wheel mechanical locks within the support scope. AutoDialer V4 is sold for lawful use by safe owners, locksmiths, and authorized technicians. The manufacturer is not responsible for misuse or damages arising from operation outside published specifications.

AutoDialer V4 is now operational 5 years in the Vietnamese market, has successfully opened every type of mechanical dial lock — turning left, turning right, including anti-manipulation safes. The operating principle is based on a systematic brute force formula: scanning all possible combinations, including numbers within the contact area — so it always finds the code.
However: The machine was developed and fully tested in Vietnam on the popular safe models here. For safe models in other countries, we do not guarantee works on all lock lines. Customers should research their lock model carefully before ordering.
Machine includes detailed user manual in English with step-by-step illustrations. Simple design: mount it, choose the direction, press the button — if you know how to use a mechanical dial lock, you'll know how to use this machine.
