Picture of 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.

As with all potential unlawful behavior associated with the use of these tools I accept no legal responsibility for your actions or the digestion or use of this information.

This is my first Instructable PLEASE COMMENT and tell me what you think.

Step 1: Gather Your Supplies...

For this project you will need the following:

1. Small hinged tin (Altoids work well)
2. Tin snips (Scissors may work)
3. Clay
4. File (Optional)
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.

Pour hot solder straight into the mould? Would this work?

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!

melt metal and pour it in and you can copy your own key
nerd127 years ago
you can put wax or clay in the clay to make it a key
that won't work to open the lock, wax breaks, clay disfigures
not plasticine potters clay or m-seal

or jb weld?

if it stays hard and does not break then ok.
it should also be heat ristance
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.
Perhaps solder?
solder wont be able to mole perfectly to it it beads, not sets

to make the key, somebody could pack the mold with baking soda, the put some superglue on it. It quickly hardens to a stone-like material.
have you done this before
Not to make a key, but for anything else that needs a strong filler, it works great
ok ty for info

what would you use to make the copy to be used
You could buy or obtain a blank key close to the molded one and carve out the teeth yourself.
Try using solder!
solder will just stick to the gun
you could use a putty, or something different from the clay

i used cheese once in Vietnam they fed me milk that was unprocessed and stale bread! they locked me up so i had the milk sit there and i stired it with my finger until it turned in cheese. then i made a mold out of the clay under the dirt floor. I just had to keep digging

what about filling it iwth fimo, taking the mould baking it put more fimo in imprint take it out then bake that?
if you want to add a bit of realism add cardboard and put small washers over it so that when its rattled it sounds like there are mints

If you make the mould as in above you could make a copy by melting some lead to get the keyshape but the lead copy would be too soft to be functional unless you could spray something like super glue onto it I was thinking epoxy resin or milliput might wotk too you could make the key out of plastic or fibreglass possibly
you might could electroplate something onto the lead to make it stronger?
electroplating only leaves a layer a couple of microns (100th of a mm) thick, so I don't think plating world make it any stronger

Why not use homemade salt dough, then you can harden it yourself at home?
no salt dough crumbles. i've made it before for school, and if you tried to put pressure or anything on it it would probly just snap. if you ask me, i would melt some colored wax into the mold, then take a high resolution picture of it, print it out, and try to carve that out of something like a soda can.
There are many types. I've used some that are pretty strong.
isnt salt dough just homemade playdough
