Broken Key in Lock? What to Do and How Much It Costs in Farmington NM

You feel the key bind, apply a little more force — and you’re holding half a key with the other half stuck inside the lock. Worn keys, frozen Farmington cylinders, and old lock hardware create exactly this situation. Here’s what to do immediately, what not to do, and what professional extraction costs.

Why Keys Break in Farmington Locks

Key metal fatigues with every use — a key copied 2–3 times has lost precision. Add Farmington’s temperature extremes (frame expansion in summer causes key binding, frozen cylinders in winter add torque resistance), and forcing a binding key breaks it. Most breaks happen at the blade’s first shoulder, leaving the fragment deep in the cylinder.

What NOT to Do

• Do not try to grab it with your fingernail — pushes it deeper, makes extraction harder
• Do not use superglue — fills the cylinder with adhesive, turns a $75 extraction into a $200 cylinder replacement
• Do not continue turning the lock — torque wedges the fragment deeper into the shear line
• Do not drill the lock yourself — incorrect drilling destroys the cylinder and requires full replacement

How Professional Key Extraction Works

A locksmith uses thin hooked extraction picks to catch the broken fragment and pull it straight out. Process: lubricate with graphite, insert hook above the key blade’s edge, rotate to catch the fragment, pull steadily outward. Most residential extractions take 5–15 minutes and leave the cylinder fully functional and undamaged.

After Extraction: Get a Fresh Key Cut from Lock Code

After the broken piece is out, have the locksmith cut a new key directly from your lock code — more accurate than copying a worn key. They’ll also inspect the cylinder for wear while it’s disassembled and tell you if binding is likely to repeat. A fresh key on a serviced cylinder lasts years without issues in Farmington’s climate.
