How Broken Key Extraction Works
When a key breaks inside a lock, the remaining fragment is lodged in the cylinder, preventing any key from entering. Our extraction process: Step 1: We spray a lubricant into the keyway to reduce friction. Step 2: Using specialized extraction tools — spiral extractors, hook picks, or broken key extractors — we grip the broken fragment and carefully work it out of the cylinder. Step 3: Once extracted, we test the lock to ensure the pins and springs weren't damaged. Step 4: If the lock functions properly, we cut a new key from the extracted fragment or decode the lock. If the cylinder was damaged, we replace it on the spot. The entire process typically takes 10-20 minutes. We successfully extract keys without damage in 95%+ of cases.
Why Keys Break in Locks
Keys don't break randomly — there's always a cause: Worn keys — metal fatigue from years of use creates stress fractures. Using force — jamming or wiggling a key in a stiff lock instead of addressing the underlying alignment issue. Cheap key copies — low-quality brass blanks from hardware stores are softer and more prone to breaking. Frozen locks — forcing a key in a frost-locked cylinder. Worn cylinder — when internal pins wear down, keys bind and stress increases. Prevention: replace keys showing visible wear, use graphite lubricant regularly, address stiff locks before they cause key breakage, and always get quality key copies from a professional locksmith.
Should You Try to Extract a Broken Key Yourself?
DIY key extraction attempts cause more damage than the original break in most cases. Here's what goes wrong: Needle-nose pliers — the most common DIY attempt — grip the broken fragment and often push it deeper into the keyway rather than out, especially if the fragment broke flush with the cylinder face. Superglue or hot glue on a match — this occasionally works on shallow breaks but more often bonds to the keyway itself, creating a $200+ cylinder replacement situation. Bobby pins and paperclips lack the specific geometry of extraction tools and cause pin tumblers to jam, turning a $65 extraction into a full cylinder replacement. If the fragment is visible and protrudes even slightly from the keyway, you can try needle-nose pliers with gentle outward pressure — but stop immediately if the fragment moves deeper. In all other cases, call a locksmith. MyKey's extraction tools cost $200+ and are designed specifically for this task. We extract broken keys in 20-30 minutes without damage in the vast majority of cases.
Broken Key Extraction Pricing in Dallas-Fort Worth
Broken key extraction from a door lock runs $65-85 in Dallas-Fort Worth, which includes the extraction and a test of the lock to confirm full function. If you need a new key cut from the existing lock (necessary when the original key was the only copy), add $15-25. If the extraction reveals that the cylinder pins were damaged in the break (uncommon but possible if the key broke under torque), cylinder replacement runs an additional $65-150. Car ignition extraction is priced separately at $85-125, because ignition cylinders are more complex to access and the extraction process is more involved. We provide a firm quote before starting — you know the maximum cost before any work begins. Compare this to the alternative: a new cylinder installed runs $95-200 for door locks, $150-300 for ignitions. Extraction is almost always the more economical option when the cylinder itself is undamaged. Call (214) 888-8755 for same-day broken key extraction anywhere in DFW.
Frequently Asked Questions — Broken Key Extraction Dallas
Can a broken key be extracted from a car ignition?
Yes, though ignition extraction is more complex than door lock extraction. The ignition cylinder is recessed and surrounded by the steering column, requiring different tools and techniques. MyKey handles ignition extractions for all vehicle makes and models across DFW. Cost is $85-125, and most extractions are completed on-site in 30-45 minutes.
Will the lock be damaged after key extraction?
In the vast majority of extractions, the cylinder is undamaged and the lock functions normally with a new key after extraction. Damage occurs only if the key broke under significant torque or if a previous DIY extraction attempt forced debris further in. We test the lock after every extraction and inform you of any pin damage before billing.
How do keys break inside locks, and how can I prevent it?
Keys break for three reasons: worn key metal (especially brass keys used daily for 5+ years), a stiff lock that requires excessive torque, or using the wrong key in a lock. Prevent breakage by replacing keys that show visible wear, lubricating stiff locks with graphite powder rather than forcing them, and never using key extensions or pliers to turn a stiff lock.
