Super Glue is famous for creating strong bonds fast. Surfaces that come in contact with Super Glue, whether intentional or not, quickly become adhered. If Super Glue has accidentally -- or purposefully -- found its way into or onto your lock -- it'll need to be removed. The ability of your lock to function properly is dependent upon complete removal of the Super Glue.

Skill level:

  1. 1

  2. 2

    Wipe softening Super Glue with clean cotton swabs.

  3. 3

    Sand or file remaining Super Glue residue with a nail file or sandpaper. Rub back and forth to wear off the glue.

    Chip off any last traces of Super Glue residue from the outside or inside of a lock using a Flathead screwdriver. Be careful to chip only at the glue and not damage the lock.

Tips and warnings

  • You may substitute straight acetone from a hardware store, but wear gloves and open windows for ventilation.
  • Wear protective gloves and goggles when working with Super Glue and cover surfaces you don't want glued with aluminium foil.
  • When a large amount of Super Glue has been squirted into the inner workings of your lock you may have to call a locksmith.
