Je Suis Un Espion: Key Mold




Be a super secret, covert spy with simple homemade tools such as this Key Mold. This is a tool for making molds of people's keys while they are still on the ring. "Why would I want a mold of a person's keys?" you’re asking yourself. Well with a mold of a key a copy could be made to allow you to access all sorts of locked... well, locks.

5. Keys (from unsuspecting mark)

Step 2: Construction...

Mark the tin lid while closed to make a sufficient cut for a key to be placed into the tin.

Cut a notch in the tin to allow the key to be placed into the tin.

Work the clay into the tin bottom and lid.

Step 3: Use the Key Mold...

To use the key mold open lid and press key into clay. Close the lid. Squeeze tin shut. Open lid. Gently lift key out. Close lid and save mold.

    I used a wet set clay as it stays mailable longer when not wrapped in airtight packaging

    For card keys one should use a plastic box as the key might be demagnetized by the metal of the box you used. ;D

    just fill with wax, let harden, place resulting wax key gently into plaster, after plaster sets heat and pour our wax, fill plaster mold with molten metal, high strength epoxy etc, gently break away plaster
    you now have a key

    After this, how do you make another copy of the key ? Do you go to a store or can you do it yourself ?

    if u melt down metal use bismuth low melting point can be melted on stove.

    Hey SWV, I like your instructable, but think it could be improved upon by moving the notch to the side a bit more, then making another notch on the other side of the tin diagonal to the first notch. Then both sides of the key could be duplicated, and lined up for filling. It could be possible to have both parts line up well enough that they could be pressed lightly together to ease the filling/cooling process for the duplicate with some thinking.
    Then again, one could just fill the impression with whatever metal they've got around, then remember the style/shape of the key they're copying and request their semi-key to be cut using a store's proper blank.

    Nice one!

    or you could use the lost wax method. it was used by Indians in the indus valley. they would make a wax model of the desired shape (like a statue) then cover it with earthen clay. when the clay dried and set they would melt the wax and pour it out. then they had a perfect mould. they would then pour molten metal into the mould and leave it to harden. after hardening break the clay mould and you have a statue left.
