Broken Key Stuck in Lock? We’ll Extract It Without Damage
You turned your key and felt it snap. Or you pulled it out and half stayed inside the lock. Now you have a broken key stuck in your door lock, car ignition, or business entrance.
You can see the broken fragment inside the lock. Maybe a tiny bit is sticking out. Maybe it’s completely inside the cylinder. You can’t unlock the door. You can’t lock the door. You’re stuck with a useless lock and half a key in your hand.
Don’t try to extract it yourself. Don’t spray glue hoping to pull it out. Don’t push it further in.
South Austin Locksmith provides professional 24/7 emergency broken key extraction service throughout Greater Austin. We’ll safely remove the broken key fragment, cut you a new key, and have your lock working again in 30-60 minutes.
Call (512) 354-0025 now for immediate broken key extraction service.
How Keys Break in Locks
Worn Keys (Metal Fatigue)
Most common cause of broken keys:
- Key has been copied multiple times (each copy slightly degrades)
- Original key is 5-10+ years old (metal weakens over time)
- Key has visible wear grooves from years of use
- Brass becomes brittle with age and repeated flexing
Signs your key is about to break:
- Deep grooves worn into key blade
- Key is visibly bent
- Key is rough/jagged from wear
- Key feels “mushy” when turning (worn pins)
Prevention: Replace worn keys before they break ($5-$15 per key vs. $75-$200 for extraction + new key).
Forcing Stuck Locks
Second most common cause:
- Lock is stiff or jammed
- You turn key harder to compensate
- Key twists under stress and snaps
Usually happens when:
- Lock is frozen (winter)
- Lock is dirty (hasn’t been cleaned in years)
- Lock is rusty (exposure to weather)
- Key isn’t fully inserted (catches on first pins)
Prevention: If lock is stiff, spray lock lubricant (graphite or silicone). NEVER force a stuck lock.
Temperature Extremes
Metal becomes brittle in cold:
- Sub-32°F temperatures make brass brittle
- You turn key normally but cold metal snaps
- Common in Austin during rare freezes
- Car locks especially prone (more exposed to weather)
Prevention: In freezing weather, warm key with hands before inserting. Never force a frozen lock.
Cheap Key Copies
Hardware store key copies use soft brass:
- Original manufacturer keys use hardened brass
- Hardware store blanks use cheaper, softer brass
- Soft brass wears faster and breaks easier
- After 2-3 generations of copies, key is significantly weaker
Prevention: Get keys copied by professional locksmith. We use high-quality blanks matching original key hardness.
Lock Problems
Sometimes the lock causes the break:
- Lock cylinder is failing (pins are sticking)
- Lock springs are weak or broken
- Lock cylinder is misaligned
- Foreign object in lock (dirt, graphite buildup)
If key breaks: The lock may need replacement, not just the key.
Why DIY Broken Key Extraction Usually Fails
The Tweezers Disaster
What you try:
- Grab visible key fragment with tweezers
- Pull hard
What happens:
- Tweezers push key deeper into lock (narrower at back)
- Key fragment now completely inside cylinder
- Much harder to extract
- You’ve made problem worse
The Super Glue Catastrophe
What you try:
- Put super glue on broken key shaft
- Press against stuck fragment
- Wait for glue to dry, pull hard
What happens:
- Glue spills into lock cylinder
- Glue bonds to lock pins and springs
- Lock is now permanently damaged ($150-$300 replacement)
- Key fragment still stuck
- You’ve destroyed the lock trying to save $75
NEVER use glue in locks.
The Paperclip Probe Disaster
What you try:
- Straighten paperclip
- Try to hook key fragment from behind
- Wiggle and pull
What happens:
- Paperclip pushes key deeper
- Paperclip damages delicate lock pins
- Lock cylinder scratched
- Key fragment still stuck
- Lock may not work even after professional extraction
The WD-40 Mistake
What you try:
- Spray WD-40 into lock
- Hope key fragment slides out
What happens:
- WD-40 attracts dirt and dust
- Creates sticky residue in lock
- Makes professional extraction harder
- Lock will need cleaning after extraction
- Key fragment still stuck (WD-40 doesn’t help extraction)
Use graphite lubricant, NEVER WD-40 in locks.
Our Professional Broken Key Extraction Process
1. Assessment - Understanding the Problem
When you call (512) 354-0025), we ask:
- Where is key broken? (door lock, car ignition, deadbolt)
- How much is visible? (tip showing vs. completely inside)
- What type of lock? (deadbolt, knob, ignition, padlock)
- Can you lock/unlock with broken piece inside? (assesses lock function)
We provide upfront price quote based on complexity.
2. Mobile Dispatch - We Come to You
Our technician arrives with specialized extraction tools:
- Broken key extractors (hook and blade types)
- Lock picks (to align pins for extraction)
- Tweezers and hemostats (for visible fragments)
- Lock cylinders (in case replacement needed)
- Key cutting machine (for new key)
Response times:
- South Austin: 20-30 minutes
- Greater Austin: 30-45 minutes
- Surrounding cities: 40-60 minutes
3. Lock Assessment
Technician examines:
- How deep is key fragment?
- Is any portion visible?
- What type of lock mechanism?
- Is lock still functional? (can we pick it open first?)
- Is lock damaged or just key broken?
Important: If door is locked AND key is broken inside, we may need to pick lock open first, then extract key.
4. Extraction Process
For keys with visible portion:
- Use extraction tool (thin metal blade with hook)
- Slide tool alongside key fragment
- Hook catches key grooves
- Gently pull fragment out
- Takes 10-20 minutes
For keys completely inside cylinder:
- Use lock pick to align pins
- Create space around key fragment
- Slide extraction tool past key
- Hook and pull fragment out
- Takes 20-40 minutes
For stubborn extractions:
- Partially disassemble lock (remove cylinder)
- Access key fragment from rear
- Push key out from inside
- Takes 30-45 minutes
Last resort (rare):
- Drill lock cylinder
- Remove cylinder entirely
- Extract key from cylinder
- Replace cylinder with new one
- Takes 40-60 minutes, costs $150-$300 total
5. Lock Testing
After extracting key fragment:
- Test lock with new key
- Ensure all pins are functioning
- Verify lock turns smoothly
- Check for internal damage
- Spray graphite lubricant (prevents future sticking)
6. New Key Cutting
We cut new key on-site:
- Use key code (if available) or decode lock
- Cut key to original specifications
- Test key in lock multiple times
- Cut 2-3 spares to prevent future issues (recommended)
You have working lock and key in 45-75 minutes total.
