Assess the Situation

  • Determine how much of the key is stuck in the lock and whether you can see or grip it.
  • Do not attempt to force the lock open or insert the remaining part of the key.

Use Tools to Extract the Broken Key

  • Tweezers or Pliers: If part of the key is visible, gently grip and pull it out. Be careful not to push it further into the lock.
  • Broken Key Extractor Tool: Available at hardware stores, this tool is specifically designed to remove broken keys. Insert it into the lock and pull out the key.
  • Super Glue Method: If the key is deep inside and visible, you can try attaching the broken piece of the key to the part inside using a small amount of super glue. Be extremely careful to avoid gluing the lock mechanism.

Lubricate the Lock (Optional)

  • Spray a small amount of graphite or lock lubricant into the keyhole to make it easier to extract the key. Avoid using oil-based lubricants, as they can gum up the mechanism.

Contact the Storage Facility

  • Inform the facility management of the situation. They might have procedures in place for handling broken locks or might recommend a trusted locksmith.

Prevent Future Issues

  • Check your keys regularly for signs of wear and tear.
  • Use a high-quality lock designed for storage units to reduce the chance of key breakage.
