Why Do Keys Break Inside Locks?

Before understanding how locksmiths extract broken keys, it’s important to know why it happens.

1. Worn or Old Keys

Keys wear down over time. The teeth become smooth, thin, or weak, making them more likely to snap under pressure.

2. Old or Poorly Maintained Locks

Locks accumulate dirt, dust, and internal wear. When resistance increases, keys are forced—leading to breakage.

3. Forcing the Key

Turning too hard, especially when the lock is stuck or frozen, is one of the most common causes.

4. Misaligned Doors

If the door or frame is misaligned, pressure builds inside the lock, stressing the key.

5. Cheap Key Copies

Poor-quality duplicates made at kiosks often break easily.

What NOT to Do When a Key Breaks in a Lock

This is critical.

Do NOT push the broken piece further in
Do NOT use glue
Do NOT insert another key
Do NOT use paper clips or needles
Do NOT force the lock

These mistakes usually make extraction harder and may require full lock replacement.

How Locksmiths Extract Broken Keys (Step-by-Step)

Professional locksmiths use specialized tools and techniques to remove broken keys without damaging the lock.

Here’s how it’s typically done:

1. Inspecting the Lock

First, the locksmith examines:

How deep the key is stuck
Whether part of it is visible
The type of lock (deadbolt, cylinder, car lock, etc.)
The condition of the lock

This determines the safest extraction method.

2. Lubricating the Lock

A professional lubricant (not WD-40) is applied to reduce friction and allow the broken key to slide out smoothly.

This step is crucial and often skipped by DIY attempts.

3. Using a Broken Key Extractor Tool

Locksmiths use specialized tools designed to:

Slide alongside the key fragment
Hook onto the broken teeth
Gently pull the piece out

These tools are thin, precise, and designed not to damage internal pins.

4. Tweezers or Needle-Nose Pliers (When Possible)

If part of the key is sticking out, a locksmith may carefully grip and remove it.

This only works when done correctly — otherwise the key can snap further inside.

5. Lock Disassembly (If Necessary)

If the key is deeply lodged or the lock is damaged, the locksmith may:

Remove the cylinder
Extract the key internally
Reassemble or rekey the lock

This method ensures no permanent damage.

6. Testing and Re-Keying

After extraction, the locksmith:

Tests the lock thoroughly
Checks for internal damage
Re-keys or replaces the lock if necessary
Cuts a new key if needed

Can You Remove a Broken Key Yourself?

Sometimes — but rarely.

You might succeed if:

A large portion of the key is visible
The lock is not damaged
You have proper tools

However, most DIY attempts end in:

Pushing the key deeper
Breaking tools inside the lock
Damaging the cylinder
Needing a full lock replacement

Calling a professional is almost always cheaper in the long run.
