If someone has put crazy glue (super glue) inside a lock, it’s a serious problem — especially if it’s dried. Here’s what you need to know and how to handle it:

🔐 Why Crazy Glue in a Lock Is Bad

  • Super glue bonds metal and plastic instantly.

  • Once it dries inside a lock cylinder, it can destroy the internal pins or completely seize the mechanism.

  • Most lubricants, solvents, or cleaners will not dissolve it effectively once cured.

✅ What You Can Do (Realistically)

1. If the Glue is Still Wet:

  • Act quickly.

  • Use acetone (like in nail polish remover) to try dissolving it.

    • Soak a cotton swab or syringe and apply inside the keyhole.

    • Be cautious—acetone can damage plastic parts and finishes.

2. If the Glue Has Dried:

You now have two realistic options:

Option A: Replace the Cylinder

  • Remove the lock cylinder (if possible) and replace it.

  • If it’s a deadbolt or doorknob, the cylinder can often be swapped without replacing the whole lock.

  • This is faster and more cost-effective than trying to fix it.

Option B: Drill and Replace the Lock

  • If it’s beyond saving, a locksmith will likely drill out the lock and install a new one.

  • Caution: If you’re not experienced, don’t attempt this yourself—you can damage the door.

🧰 Tools a Locksmith Might Use

  • Plug spinner (if partially working)

  • Locksmith-grade lock lubricant

  • Extractor kits

  • Drill + rekeying tools

  • Replacement cylinders or full locks

💡 Tip:

If this was done maliciously, consider:

  • Filing a police report (especially if it’s part of ongoing harassment).

  • Installing a camera for security.

  • Using high-security locks that are tamper-resistant.
