    With the lock now exposed, remove the small metal rod with your pliers, being careful not to damage the lock core in the process.

  3. 3

    Cover the cloth in the cleaning fluid and wipe clean any dirt in the lock core, making sure to also wipe clean the hole which you took the small rod from.

    Insert the new rod into the lock core, and use the wrench to press down on the rod and lock to click into place. You can buy a small metal rod to use for this project from most hardware stores and DIY outlets.
