What To Do If a Key Breaks Inside the Lock

A broken key stuck inside a lock is a common problem for homeowners, drivers, and business owners. Keys weaken over time due to wear, pressure, and environmental factors such as Charleston’s humidity and salt air exposure. Knowing how to respond correctly can prevent permanent lock damage and costly repairs. Here at Charleston Locksmith Pro, we offer professional broken key extraction services that can rapidly and safely restore lock functionality and get you back inside as soon as possible. In this blog entry, our expert Charleston lockout service team will describe some useful tips for extracting keys that have broken off inside of your locks.

Why Keys Break Inside Locks

Keys can snap when they become fatigued or too much pressure is applied to them. Old keys can become weakened at certain points from extended use. If your lock cylinder isn’t lined up correctly, it may cause friction as you turn the key. Metal contracts in colder temperatures and can become brittle. Knowing how your key broke will allow you to avoid repeating the same problem.

• Metal Fatigue – Repeated use weakens key structure.
• Worn Key Grooves – Thin edges break under pressure.
• Lock Misalignment – Increases turning resistance.
• Corrosion Buildup – Creates internal friction.
• Excessive Force – Twisting too hard snaps the key.Safe Extraction Techniques

Our locksmiths have extraction tools to take broken pieces out. Key Extractors can be slid into the cylinder with the broken piece. Tweezers can be used if you can see the broken piece. Lubricate the lock to minimize friction as you extract the piece. The lock may need to be inspected for damage once removed.

• Key Extractor Tool – Grips and pulls fragment safely.
• Lubrication Application – Reduces friction inside cylinder.
• Cylinder Inspection – Checks for bent pins.
• Rekey Recommendation – Prevents future issues.
• Key Replacement – Cut from original code if available.

What a Professional Broken Key Extraction Includes

A trained locksmith typically:

1. Examines the lock condition

2. Uses precision extraction tools

3. Removes the broken fragment safely

4. Tests lock operation

5. Cuts a replacement key if needed

Most extractions can be completed without replacing the lock.

Preventing Future Breakage

Routine maintenance will help you keep your keys and locks lasting longer. Replace keys before they break to minimize your risk. Use a graphite lubricant to keep the pins moving freely. Do not force the key when you encounter resistance. Maintain your locks before they start to give you problems. We recommend that you:

• Replace Worn Keys – Avoid thin or bent keys.
• Lubricate Cylinders – Use graphite for smooth operation.
• Address Resistance Early – Do not force turning.
• Schedule Lock Maintenance – Prevent internal wear.
• Use Proper Key Blanks – Ensure correct duplication.

Safety Reminder

If a broken key occurs in:

• A vehicle with a child or pet inside

• A business requiring emergency access

• A situation where you feel unsafe

Seek immediate professional assistance.
