Make A Key Mold Without A Key

Materials Needed

Before you begin creating a key mold without a key, it is crucial to gather the necessary materials. You will need silicone rubber, an old key blank, clay or epoxy putty, and a few tools like scissors and pliers. It is also helpful to have access to a heat gun or torch if available. 

Creating the Mold

Once you have all of the necessary materials and tools, it is time to begin creating your key mold. Begin by cutting the old key blank into small pieces that fit in the area where your new key will go. Press a piece of clay or epoxy putty firmly over each piece of the old key blank. This will create the profile of the new key and provide a surface for the silicone rubber to adhere to. 

Applying the Silicone Rubber

After creating a mold out of clay or epoxy putty, it is time to apply silicone rubber to make your key mold. You can use either a liquid or paste-type silicone rubber. Before applying the rubber, make sure to preheat the mold with a heat gun or torch so that it is warm when you apply the rubber. This will ensure that the silicone adheres appropriately, creating a solid bond between the key blank pieces and the mold surface.

Finishing Touches

Once you have applied the silicone rubber and allowed it to set, it is time to finish off your key mold. Carefully remove the clay or epoxy putty from the mold and use a sharp knife or scissors to trim any excess rubber. Once this is done, you can attach your new key blank pieces to the finished key mold and test it to ensure everything works correctly. 

Creating a key mold without a key is easier than you may think. With the right supplies, knowledge, and a bit of time, you can make your own key mold without purchasing an expensive key duplicator. So what are you waiting for? Try it and see how easy it is to make a key mold without a key.
