It is a frustrating experience being at your door with a key in hand and nothing. You shake, contort, push more, but the lock is not moving. And maybe you have found that your key is not working. The causes of this general problem may be varied, including wear and tear, internal lock damage, and more. Knoxmith Lock & Key is a company that specializes in diagnosing and solving key and lock problems in both residential and business settings within Knoxville, TN.
Here are the most popular causes of key failure and how to repair them.
Is Your Key Simply Worn Out?
Keys are used on a daily basis, and with time, the teeth on the keys may wear. A damaged key might not fit with the pins inside the lock correctly anymore, making it hard or even impossible to turn.
Checklist:
- Significant teeth are flattened or smooth
- The key slips in the lock and does not turn
- The lock is not responsive or loosely fitting
- Spare key fails while the original works
- The key has not been replaced in years
If your key is worn, Knoxmith Lock & Key can give you an accurate copy using precision key-cutting machines services in Knoxvile, TN. We suggest that keys be changed every couple of years to prevent unpredictable failures.
Is the Key Bent or Warped?
Keys can be used not only to open doors but also to open packages, scrape surfaces, or pry something open. Such habits can bend or warp the key, resulting in misalignment within the lock.
Checklist:
- Key appears curved or twisted
- The key gets in the lock and gets stuck or jammed
- The lock is stiff or inflexible
- The key needs too much force to rotate
- The key has been dropped or carelessly handled
Bent keys may damage the lock cylinder. Knoxmith Lock & Key offers broken key repair to restore your lock without causing further harm.
Is the Lock Cylinder the Real Problem?
There are occasions when the issue is the lock and not the key. The lock cylinder may fail due to dirt, corrosion, or internal wear, which prevents the key from fitting properly.
Checklist:
- The key won’t turn even with a new copy
- Lock feels gritty or stiff
- The lock has not been cleaned or lubricated in years
- Lock has been exposed to weather (humidity, rain)
- Key insertion causes clicks or grinding sounds
Knoxmith Lock & Key offers lock cylinder diagnostics and maintenance. The problem can often be lock fixed with a simple cleaning or rekeying, without needing full replacement.
Did Something Break Inside the Lock?
Locks contain springs, pins, and other small components that may fail or shift over time. A broken spring or misaligned pin can prevent the key from turning even if the key itself is fine.
Checklist:
- The key is frozen or cannot be removed
- The lock turns halfway but does not engage
- The lock feels loose or rattles
- The lock was recently pounded or forced
- The key worked fine until a specific incident
If internal damage is suspected, Knoxmith Lock & Key can disassemble and inspect the lock. We offer fast lock repair or replacement to restore access immediately.
Is There Debris Blocking the Lock?
Dust, lint, or fragments of a broken key can jam the lock mechanism. This is especially common in older locks or those exposed to outdoor elements.
Checklist:
- The key won’t insert fully
- The lock feels clogged or sticky
- The key broke off inside the lock
- The lock has not been cleaned in years
- The lock is located in a dusty or high-traffic area
Our technicians use specialized tools to clear debris and restore smooth operation. If the lock cannot be cleaned, we offer cost-effective replacement options.
Have You Tried a Spare Key?
Test a backup key before making assumptions. If the spare works, the original key is likely the problem. If both fail, the lock may be the issue.
Checklist:
- Spare key turns smoothly
- The original key shows visible wear
- Lock responds differently to each key
- The spare key was cut recently
- The key has been duplicated multiple times
Knoxmith Lock & Key can cut a new key from the original code, ensuring precision and durability. We also offer worn key replacement to prevent future failures.
Should It Be Rekeyed or Replaced?
If both your key and lock are old, rekeying or replacing the lock may be the best solution. Rekeying involves adjusting the lock’s internal pins to match a new key, while replacement installs a brand-new lock.
Checklist:
- The lock is more than 10 years old
- Multiple keys have failed
- The lock has been forced or broken
- You want to upgrade security
- You’ve lost track of who has copies of your key
Knoxmith Lock & Key provides lock replacement and rekeying services for homes and businesses. We help you choose the right solution based on budget, urgency, and security needs.
