Lock Won't Work? Common Issues & Fixes | NWI Locksmiths LLC

1. Key Won't Turn in the Lock

Problem

One of the most common issues is a key that won't turn in the lock. This can be caused by various factors such as dirt or debris inside the lock, a worn-out key, or a misaligned lock mechanism.

Solution

• Lubricate the Lock: Apply a small amount of graphite or Teflon-based lubricant to the keyhole. Avoid using oil-based lubricants, as they can attract dirt and make the problem worse.

• Check the Key: Inspect the key for signs of wear and tear. If the key is damaged, have a new one cut from a master key.

• Realign the Lock Mechanism: If the lock is misaligned, try to gently wiggle the key while turning it. In some cases, the lock might need to be realigned professionally.

2. Key Stuck in the Lock

Problem

A key stuck in the lock can be a frustrating experience. This issue can occur due to a misaligned lock cylinder, a bent key, or debris inside the lock.

Solution

• Lubricate the Lock: Similar to the first problem, applying a graphite or Teflon-based lubricant can help. Insert the lubricant into the keyhole and gently wiggle the key until it comes loose.

• Check the Key: If the key is bent, straighten it carefully or use a spare key.

• Remove Debris: If you suspect debris inside the lock, use a compressed air canister to blow out any dirt or particles.

3. Broken Key in the Lock

Problem

A key breaking off inside the lock can render the lock unusable and pose a significant security risk.

Solution

• Extract the Key: Use a pair of needle-nose pliers to carefully extract the broken key piece. If the key is deeply lodged, a broken key extractor tool can be used.

• Call a Locksmith: If you cannot remove the broken key, it’s best to call a professional locksmith to avoid damaging the lock further.

4. Lock is Hard to Turn

Problem

A lock that is hard to turn can be due to internal corrosion, dirt buildup, or a misaligned door and frame.

Solution

• Clean and Lubricate: Clean the lock with a non-residue cleaner and lubricate it with a graphite or Teflon-based lubricant.

• Check Door Alignment: Ensure that the door and frame are properly aligned. If necessary, adjust the hinges or strike plate.

• Replace the Lock: If the lock is old and corroded, it might be time to replace it with a new one.

5. Lock Cylinder Turns But Doesn't Lock/Unlock

Problem

When the lock cylinder turns but doesn't engage the locking mechanism, it can be due to a detached or broken set screw or tailpiece.

Solution

• Inspect the Lock: Remove the lock from the door and inspect the internal components. Check if the set screw or tailpiece is broken or detached.

• Tighten or Replace Components: Tighten any loose screws or replace broken parts. If you're not comfortable doing this yourself, consult a locksmith.

6. Misaligned Door Latch

Problem

A misaligned door latch can prevent the lock from engaging properly, making it difficult to lock or unlock the door.

Solution

• Adjust the Strike Plate: Loosen the screws on the strike plate and adjust its position until the latch aligns correctly. Tighten the screws once the latch fits snugly.

• File the Strike Plate: If minor adjustments don’t solve the problem, use a metal file to enlarge the hole in the strike plate slightly.

7. Frozen Lock

Problem

In cold weather, locks can freeze, making it impossible to insert or turn the key.

Solution

• De-icer Spray: Use a lock de-icer spray to melt the ice inside the lock.

• Warm the Key: Heat the key with a lighter or warm water and insert it into the lock. Be cautious not to burn yourself.

• Preventive Measures: Apply a silicone-based lubricant before the cold season to prevent the lock from freezing.

Lock problems can be inconvenient, but with a bit of knowledge and the right tools, many issues can be resolved quickly and easily. Regular maintenance and prompt attention to minor issues can also help prevent more serious lock problems in the future. However, if you encounter a complex lock issue or are unsure how to fix it, don’t hesitate to contact a professional locksmith. Ensuring your locks are in good working condition is essential for your security and peace of mind.
