How Locksmiths Open Locks Without Damaging Them

One of the most common concerns people have when they call a locksmith is: “Are you going to have to drill the lock?”
The good news is, in most cases, no.
Professional locksmiths are trained to use non-destructive entry techniques, which means gaining access without damaging your door, lock, or hardware wherever possible.

In fact, British TV recently had a feature on a dodgy locksmith who was demanding customers pay for him to drill their locks, instead of unlocking it:

Whether you are locked out of your home in Kew or dealing with a commercial lock issue in Melbourne, the goal is always to restore access safely and preserve your existing hardware.

Here’s how it works.

What is Non-Destructive Entry?

Non-destructive entry refers to techniques used to unlock a door without drilling, cutting, or replacing the lock. It relies on skill, specialist tools, and an understanding of how different lock mechanisms function internally.
Most residential and commercial locks in Australia use pin tumbler systems, which can often be manipulated open without damage when handled by a trained professional.

Lock Picking (Yes, It’s Real)

Lock picking is not just something you see in movies. In legitimate locksmithing, it is a precise and controlled process.

Using specialised tools, a locksmith gently manipulates the pins inside the lock cylinder to align them correctly, allowing the plug to turn. When done properly, the lock remains fully functional afterwards.

As in the video above, we don’t need to drill in most cases.

This method works best when:
  • The lock is in good condition
  • There is no internal damage
  • The key has simply been lost or left inside
It requires training and experience, not force.

Lock Bypassing Techniques

Some locks can be opened with bypass tools that exploit mechanical design features. For example, certain latch mechanisms can be slipped open without touching the internal pins.

Modern high-security locks are designed to resist bypassing, but standard residential locks may allow for this method when appropriate.

Decoding and Impressioning

In certain situations, especially where the lock is intact, but the key is missing, locksmiths may use decoding or impressioning techniques to create a working key without removing or destroying the lock.
This involves analysing the lock’s internal configuration to determine the correct key-cut pattern.

That isn’t to say that drilling a lock isn’t sometimes necessary. Let’s dive into when it is…

When is Drilling Necessary?

While non-destructive entry is always preferred, there are cases where drilling becomes unavoidable:
  • The lock is severely damaged
  • The internal mechanism has failed
  • The lock is high-security and cannot be picked
  • Someone has attempted forced entry and compromised the cylinder
In those cases, drilling is controlled and precise. The lock cylinder is replaced, and your door remains intact.

Why Experience Matters

Non-destructive entry is not guesswork. It requires:
  • Understanding of Australian lock standards
  • Knowledge of different brands and models
  • Professional tools
  • Patience and precision
An inexperienced operator may default to drilling immediately. A qualified locksmith will attempt safe entry methods first.
