A broken key stuck inside your lock is frustrating and inconvenient, especially when you need to leave right now. Maybe you turned the key a little too hard, maybe it was already worn thin, or maybe the lock itself is stuck either way, half your key is now trapped inside a lock, and yanking on the visible piece isn’t helping.
Here’s what you need to know about getting that broken key out safely, what it costs, and when to call a professional instead of making things worse with pliers and YouTube tutorials.
What Broken Key Extraction Actually Costs
Most broken key extractions in the Dallas-Fort Worth area run between $75 and $150, depending on where the key broke and how stuck it is.
| Lock Type | Typical Extraction Cost | Time Required |
|---|---|---|
| House door lock | $75–$120 | 15–30 minutes |
| Car door or trunk | $100–$150 | 20–40 minutes |
| Ignition cylinder | $125–$200+ | 30–60 minutes |
| Padlock or mailbox | $60–$100 | 10–20 minutes |
Emergency calls after hours or on weekends usually add $50–$75 to the base price. If the lock is damaged during removal or the key broke because the lock itself is failing, you may also need lock replacement.
At 469 Authorized Locksmith, we give you the full cost upfront before we start no surprises, no “oh, this will cost more” halfway through the job.
Why Keys Break Inside Locks and Ignitions
Keys don’t just snap for no reason. Usually it’s one of these:
- Worn-down key teeth: After years of use, the grooves get shallow and the metal thins out. Eventually it can’t handle the torque.
- Forcing a sticky lock: If the lock is corroded, dirty, or misaligned, forcing the key puts all the pressure on a small section of metal and it snaps.
- Cheap duplicate keys: Keys cut at a hardware store kiosk are often made from softer metal than the original. They bend and break easier.
- Extreme cold: Metal contracts in freezing temperatures, making keys more brittle. This is common in car ignitions during Dallas cold snaps.
If your key was already hard to turn before it broke, the lock likely needs cleaning or repair. Extracting the key won’t fix the underlying problem. If you’ve noticed your spare key sticking in the ignition, get the lock serviced before it snaps too.
What NOT to Do When Your Key Breaks
Here’s where most people make it worse:
- Don’t spray WD-40 or oil into the lock. It gums up the pins and makes extraction harder. If you’ve already done this, tell the locksmith we need to flush it out first.
- Don’t try to glue the broken piece back together. Superglue inside a lock cylinder is a nightmare and usually means replacing the entire lock.
- Don’t keep turning the broken stub. If part of the key is still turning, stop. You’re pushing the broken piece deeper into the cylinder.
- Don’t use needle-nose pliers unless you can grip the key firmly. If you push the broken piece further in, even a professional extraction becomes a lock replacement.
If you can see at least 2–3mm of the broken key sticking out and the lock isn’t engaged, you might be able to pull it out with pliers. If it’s flush with the keyway or wedged in deep, call us.
How Professional Extraction Works
We use specialized extraction tools designed for this exact problem not household items. The process depends on how the key broke and where it’s stuck.
Hook and Saw Extractors
These thin, flexible tools slide alongside the broken key and hook onto the teeth. We wiggle it gently until the broken piece slides out. This works for most standard door locks and padlocks.
Cylinder Removal
For car ignitions or high-security locks, we sometimes remove the entire cylinder, disassemble it, and push the broken piece out from the back. Takes longer but guarantees we won’t damage the lock.
Key Impressioning
Once the broken piece is out, we can often make a new key on-site using the broken halves or by impressioning the lock. You’re back in business without needing to go to a dealership or hardware store.
Frequently Asked Questions
Can I drive my car with a broken key stuck in the ignition?
No. If the key broke while in the “on” position, you might be able to start the car, but you won’t be able to remove the key or lock the steering wheel. If it broke in the “off” position, the car won’t start at all.
Will extracting the key damage my lock?
Not if done correctly. Professional extraction tools are designed to slide into the keyway without scratching the pins or springs. DIY methods can wreck the lock and turn a $100 extraction into a $250 lock replacement.
How long does broken key extraction take?
Most extractions take 15–30 minutes for a standard lock. Car ignitions or high-security locks can take up to an hour if the cylinder needs to be removed.
Can you make a new key from the broken pieces?
Yes, as long as we have both halves and the cuts are still visible. We can use them as a template to cut a new key on-site. If the key is too worn or a piece is missing, we’ll impression the lock or decode the cylinder to cut a fresh key.
