A key snapped inside a lock or ignition barrel is one of those situations that gets worse the more you interfere with it. Most people's instinct is to try to pull the broken piece out with pliers, a pin, or another key — usually pushing the fragment deeper and making professional extraction harder. Mobile Auto Locksmith Hamilton carries the right specialist tools to remove broken keys from car locks, ignition barrels, and door cylinders without causing any damage to the lock itself.
“Needed a new transponder key for my Honda CRV after the original was stolen. Done in the driveway within two hours of calling. He also deleted the old key from the system. Thorough and trustworthy.”
Car keys snap in locks for predictable reasons. The blade wears thin with use — especially along the grooves that engage the lock pins. Repeated twisting under load (a stiff lock, a steering lock that has engaged at an angle, or forced entry after a lockout) creates metal fatigue. Eventually the blade cracks and fails mid-use.
Ignition barrels are a common failure point because drivers apply significant torque — especially if the steering lock has engaged. The blade snaps and one piece remains with the driver while the other is embedded in the barrel.
Door locks are another common location, particularly on the driver's door which sees the most use.
Extraction tools work by threading alongside the broken blade fragment and catching on the notches or grooves in the key. A gentle rotating motion draws the fragment towards the opening of the lock cylinder. This process requires patience and the right tools — rushing or using improvised tools causes damage to the lock pins and cylinder, turning a simple extraction into a full cylinder replacement.
We use a range of extraction tools suited to different lock types and cylinder designs. The approach we take depends on how far the fragment has gone in, whether it is rotated from the correct position, and the design of the specific lock.
Once the broken fragment is out, we assess the lock. In most cases, a properly extracted key leaves the lock in fully functional condition — no damage whatsoever. We then look at options for a new key.
If the original key is still in one piece (it broke at the bow, for example), we can often cut a new blade and reuse it. If the entire blade is gone, we cut and program a replacement key. We will always advise you on the most cost-effective approach for your specific vehicle.
Do not try to extract the broken piece yourself unless you have extraction tools. Here is what makes the job harder:
If the fragment is visible and close to the surface, leave it exactly where it is and call us. The less you interfere, the faster and cleaner the extraction will be.
A customer in Huntly called us after his 2016 Nissan Navara key blade snapped while starting the engine. He had tried to pull it out with pliers and had pushed it slightly further in. He was worried he would need a new ignition barrel.
We arrived at his rural property, assessed the situation, and used our specialist extraction tools to remove the fragment in about 25 minutes. The ignition barrel was in perfect condition. We then cut a new key blade to replace the one he had broken and had him running within the hour — no ignition replacement needed, saving him around $500.

Common questions
In most cases, yes. Using proper extraction tools, we can retrieve the fragment without touching the lock pins or cylinder walls. The lock is fully functional afterwards in the majority of jobs.
Extraction typically costs $120–$220 depending on how deep the fragment is and the lock type. This does not include a replacement key if needed — we quote that separately. Call for an exact price.
Deeper fragments take longer but are still extractable in most cases. If the fragment cannot be recovered without cylinder damage, we will discuss ignition replacement as an alternative and quote accordingly before proceeding.
The bow piece with the chip is separate from the blade. If the blade broke and remained in the lock, we extract it, then we can potentially cut a new blade to the remaining bow piece if the chip is undamaged. We assess on site.
Yes. We extract from door locks, boot locks, ignition barrels, and glovebox locks. The tools and method vary slightly but the principle is the same.
Simple extractions — fragment near the surface — take 15–25 minutes. Deeper or more complex cases can take up to 45 minutes. We are honest about timing upfront.
