LaGard 3330: opening it without drilling
What the lock is, whether a safe autodialer covers it, and what the job actually looks like from setup to open.

The lock
A Group 2 mechanical combination lock found on a wide range of commercial safes, particularly across Europe and the Middle East.
- Group 2 mechanical combination lock
- Three wheels
- Mechanical dial, no electronics
- Within the machine's supported range
Does the AutoDialer V4 open it?
The machine is built for Group 2 mechanical combination locks, three-wheel and four-wheel, with the dial turning either direction. A lock of this type falls inside that range.
Mechanically this sits in the same category the AutoDialer V4 is built for. As with any lock we have not seen, send a photo of the dial before you order and we will confirm rather than assume.
We would rather turn away an order than take one we cannot deliver on. Send a photo of the dial and the model number and we will confirm before you buy — and if the lock is outside what the machine handles, we will tell you that instead.

What opening it looks like in practice
- Mount the machine coaxially with the dial on the magnetic base and check by hand that it turns tight, smooth and without slip.
- Select the number of wheels, the dial direction and the coarse step, then start.
- Walk away. The coarse sweep on a three-wheel lock covers the whole range in about 50 minutes.
- If it finishes without opening, step down to the next finer setting and run again.
The safe is undamaged throughout, keeps its original lock, and keeps whatever certification it carried. Full timings are in how long an autodialer takes on a Group 2 lock.
What it will not help with
If the safe has an electronic keypad rather than a dial, or a time lock, or the lock's internal mechanism is already broken, a dialling machine is not the answer. A photo will usually settle which situation you are in.
Not sure whether it covers your lock?
Send a photo of the dial and the lock model. We'll tell you honestly whether the AutoDialer V4 handles it before you spend anything — and if it doesn't, we'll say so.
