What to Do When Your Key Breaks in the Lock
Step-by-step instructions for handling a broken key emergency.
If your key breaks in the lock, do not panic. First, do NOT try to use the remaining piece to turn the lock. Gently try to remove the broken piece with needle-nose pliers if it is sticking out. If that fails, call a locksmith for professional broken key extraction.
Step 1: Stay Calm and Assess
Take a moment to look at the situation:
- Is part of the key sticking out of the lock?
- Has the key broken off flush with the lock?
- Is the lock in the locked or unlocked position?
Step 2: What NOT to Do
- Do not use the other half to try to turn the lock - this can push the broken piece deeper
- Do not use glue to try to attach the pieces - this makes professional extraction harder
- Do not force tools into the keyway - you may damage the lock cylinder
- Do not drill the lock unless you are willing to replace it entirely
Step 3: DIY Extraction Methods
If part of the key is visible, you may try these methods:
Needle-Nose Pliers
If enough key is sticking out, grip it firmly with needle-nose pliers and pull straight out. Do not wiggle or twist.
Broken Key Extractor Tool
Available at hardware stores, these thin tools slide along the key to hook the broken piece. Insert alongside the key, turn slightly to engage the teeth, and pull out.
Jigsaw Blade Method
A thin jigsaw blade can work similarly to an extractor. Insert with teeth facing the key, press against the key, and pull out slowly.
Step 4: When to Call a Locksmith
Contact a professional locksmith if:
- The key is broken off flush with or inside the lock
- DIY methods are not working
- You do not have the right tools
- You are worried about damaging the lock
- You need to get inside quickly
What a Locksmith Will Do
A professional locksmith has specialized tools for broken key extraction:
- Professional extractors - Various sizes for different lock types
- Scope tools - To see inside the keyway
- Lock picks - To manipulate pins if needed
In most cases, a locksmith can extract the broken key without damaging the lock, so you can continue using it with a new key.
Preventing Broken Keys
Keys break for several reasons. Here is how to prevent it:
- Replace worn keys - If you see cracks or significant wear, get a duplicate
- Do not force keys - If a key is hard to turn, the lock may need lubrication or repair
- Use the right key - Using the wrong key can stress both key and lock
- Lubricate locks - Use graphite lubricant annually
- Avoid key chains that are too heavy - Excess weight stresses the key
After Extraction: Next Steps
Once the broken key is removed:
- Have a new key made from the broken pieces or by code
- Consider replacing the lock if it is damaged or old
- Keep a spare key to avoid emergency situations
