A broken key in an ignition or door lock is one of the more common automotive emergencies we respond to. Keys break for several reasons: years of wear weaken the blade, cold weather makes metal brittle, forcing a wrong key can snap the blade, and sometimes keys simply fail at the thinnest cross-section near the shoulder.
When a key breaks, the broken blade is still inside the cylinder, which means the cylinder is occupied and can't be operated with a replacement key until the broken piece is removed. Trying to force a new key in on top of the broken piece damages the cylinder or jams the pins. The correct fix is specialty extraction tools that grip the broken blade and pull it out intact.
Treasure Coast Locksmith handles broken key extractions from car ignitions, car door locks, car trunk cylinders, home residential locks, and commercial cylinder hardware. Most extractions take 5-15 minutes onsite with minimal disruption to the cylinder or surrounding hardware.

How keys break
Common reasons keys break and what to do about it.
Typical broken key scenarios

How broken key extraction works
Broken key extraction uses specialty tools designed to grip the broken blade without damaging the cylinder pins. The most common extractor is a thin hooked probe that slides alongside the broken blade, catches the cut pattern, and pulls the blade straight back out. Other extractors use a tapered design that wedges between the broken blade and the pins, pushing the pins out of the way while gripping the blade.
The technique varies slightly by cylinder type. For car ignitions, we first rotate the cylinder to the 'off' position (where the broken key would have been removed normally) before inserting the extractor. For home deadbolts, we use the cylinder in its normal position and extract directly.
For mortise cylinders in commercial hardware, sometimes we have to partially disassemble the lock to access the broken piece.
Rare cases require drilling. If the broken piece is so far recessed or so damaged that extractor tools cannot grip it, we carefully drill a small access hole to push the broken piece out from the other side. Drilling always damages the cylinder, so we do it only as a last resort and always with customer approval first.
After extraction, we cut a replacement key from the extracted pieces or from the cylinder itself (by impressioning or reading the pin stack). For transponder keys, we also program the chip to match the vehicle's immobilizer. The whole process from extraction to a working replacement key typically takes 30-60 minutes onsite for automotive applications.

Broken key prevention tips
- Never force a key that feels wrong - you're about to snap the blade.
- Replace worn keys before they break - cut a fresh copy when the original gets weak.
- Don't use a car key as a screwdriver, bottle opener, or package opener - metal fatigue builds up.
- Lubricate ignition cylinders annually with dry graphite to prevent binding and key wear.
- If your key is turning harder over time, rekey the cylinder before it seizes and breaks the next key.
- Keep spare keys separate from daily-use keys so you're never reliant on a single key.

Broken key extraction FAQs
Common questions about broken key removal.
How much does broken key extraction cost?
Typical extraction plus new key runs $95 to $185 for standard cylinders. Transponder key extraction and programming runs $165 to $295 including replacement chip programming. Smart key replacement after extraction runs $245 to $395.
Cylinder replacement if damaged adds $125-$245.
Can you remove a broken key without damaging the lock?
Yes in 95% of cases. Specialty extractor tools are designed to grip the broken blade without touching the pins or pin springs. Non-destructive extraction works on car ignitions, door locks, trunk cylinders, and home deadbolts.
Drilling is a last resort and only with your permission.
How long does broken key extraction take?
Typical extraction is 5-15 minutes. Complicated cases (deeply broken blade, rusted cylinder, damaged pins) can take 20-45 minutes. Follow-up key cutting and programming adds 15-45 minutes depending on whether the key is transponder or smart.
Total job time 30-90 minutes.
Can you cut a new key from the broken pieces?
Usually yes. If the broken pieces are complete and not heavily worn, we reassemble them to read the cut pattern and cut a new key from that. If pieces are missing or too worn, we cut from the cylinder itself by impressioning or from the VIN code if we have access to the database.
What if my key broke in the ignition and won't turn?
Extraction first, then diagnosis. Usually the cylinder is fine after extraction and we can cut a fresh key that works normally. If the cylinder is damaged (bent pins, worn springs), we recommend rekey or replacement.
We assess onsite and tell you the options.
Can you extract a broken transponder key?
Yes. The extraction process is identical for transponder keys and non-transponder keys - we're extracting the mechanical blade, not the plastic head with the chip. After extraction, we program a replacement chip into the new key.
Common on Ford, Honda, Toyota, and GM vehicles.
What if part of the key is missing?
We can often cut a replacement even with missing pieces. If we have the shoulder (the part with the bow where you grip the key), we can measure the cut pattern from the cylinder pins via impressioning. If only a tip fragment broke off, we can sometimes match the pattern by examining the remaining key blade.
Is extraction covered by your workmanship warranty?
Yes. The extraction procedure is covered by our standard workmanship warranty. If the cylinder operates improperly after our extraction (which is very rare), we return to diagnose and repair at no additional charge.
Replacement parts are subject to manufacturer warranty separately.
Can I extract the key myself?
Sometimes, for simple cases - if enough of the key is sticking out, pliers might grip it. For keys broken flush or recessed, DIY attempts often push the broken piece deeper or damage the cylinder. The $95-$185 professional service is almost always cheaper than DIY mistakes.
Do you extract house keys too?
Yes. Residential cylinder extraction (deadbolts, handle sets, knob cylinders) uses similar techniques as automotive. Typical residential extraction runs $85-$155 including a fresh replacement key.
Commercial cylinder extraction runs slightly higher due to harder cylinder access on some mortise hardware.
Can you extract a broken mailbox or padlock key?
Yes. Mailbox cylinders (residential wall-mount, curbside, USPS CBU) use small cam lock cylinders that accept the same extractor techniques. Padlocks (shed, gate, commercial) have varied cylinder designs but extraction is usually possible.
Typical extraction $65-$125 per lock.
What if my key breaks late at night?
Emergency broken key extraction is available 24/7 via our emergency dispatch. Call (772) 758-1322 any time. After-hours surcharge applies but the typical total cost including after-hours fee is $195-$295 for standard automotive extraction.
