How to open a safe with a drill

When hearing about safes, the first thing that comes to mind is “extreme security and valuables”, such as money, jewelry and important documents. Surely the same thing happens to you, except when not we can open our own safe that, then, only “problems” come to mind, right?

Opening a safe is not an impossible mission, if we have a problem with the correct way to open it, it is possible to solve it. Therefore, on this occasion, we have prepared an article to explain you how to open a safe with drill. Although we must emphasize that this application will make the safe unusable, so if you agree with this, continue reading.

How to apply the drill

To open a safe with a drill we have two options:

  1. Drill the lock cylinder.
  2. Drill below where the lock is located.

Each of these methods corresponds to being applied in different mechanisms of safes. A little later we will talk about the difference between them and their respective application.

Another fundamental aspect that must be taken into account when we decide to use a drill to open a safe is the material with which said box is made. Because depending on that, the material of the wick or bit that we must use will be taken into account, otherwise it is possible that we will not scratch the safe.

Ideally, we should use diamond-tipped bits or bits, although carbide-tipped bits can also be used. On the market there are safes made of materials such as manganese alloys or aerated concrete. And the aforementioned drill tips are capable of drilling this type of materials, due to the hardness and resistance they possess.

Drilling the lock cylinder

This method is recommended for safes whose security system is based on a key mechanism and without a combination. Due to the fact that, by disabling the security mechanism, we can access the interior of the safe by forcing the lock, for which it is necessary to work precisely.

If a key has become stuck or broken inside the keyhole or as it commonly happens – the key has been misplaced, this is the ideal method.

It is worth noting that, although the safe will be disabled, since we will pierce its security mechanism, it is possible to recover it. This is why it is necessary to work precisely and carefully so as not to do unnecessary harm. to the box or to ourselves, since, in order to comply with this, we must only damage the lock.


Obviously, we need a drill. Perhaps in this step a special pointed bit is not necessary, although it is worth checking the material with which the safe lock is made, since it is the one that we will drill. Additionally, a flat blade or blade screwdriver is required.

  1. We start by placing the bit in the drill and tightening it well to avoid an accident from happening.
  2. We turn on the drill and without hurrying we will drill the lock, right in the key entry hole.
  3. If the bit gets stuck, we should not force it, we stop, remove the bit and continue drilling.

Now, if our case is that the key is stuck and broke inside the lock, it is possible that the bit is stuck when encountering the key.

If we are within our means, we must help the work of the drill with some tweezers (we can use a tweezer to remove eyebrows). But if we cannot reach the key piece, we can place a thicker bit, open a little space and try to reach the key piece with the pliers.

When we have a large enough opening in the keyhole, we can start turning it. At this point, the flat-head screwdriver comes into operation; we must introduce it and turn it to open the safe.

Drilling under the lock

On this occasion we can say that this method is applicable for safes whose internal mechanism is unknown. That is why it is advisable to drill, not exactly below the lock, but a few centimeters below but transversely; since the purpose of drilling is to know what the internal mechanism is and to be able to choose the best strategy.

You must understand that, although the mechanical system of the safe will not be damaged, its security will be completely lost. This is because we will not be able to safely cover the hole that we have made, so that, from then on, the safe will be a vulnerable element, so there is a chance that it should be discarded.

In addition to the drill and the bit, it will be very useful to have an endoscope during the process, to clearly observe the details of the interior of the lock.


As we have already mentioned, the application leads to drilling transversely under the lock. On this occasion, we must take into account the manufacturing material of the safe, since we will drill not the lock, but the door.

  1. To begin, we will put a bit that can pierce the door of the box.
  2. We will use the endoscope to observe the interior of the lock in detail.

At this point we have several options, depending on the mechanism that we find inside the safe. If it is a combination safe, its internal wheels will engage the mechanism with a sound.

When this happens we must turn the combination wheel in the opposite direction. In case of that we find another type of mechanismIt is very likely that it is also vulnerable, composed of a hook that with a long tool or even a wire, can be forced.

As you have surely been able to appreciate, the use of a drill to open a safe can be a very effective method, although with its use we have a factor against it, and that is the loss of operability of it.
