    First useful instructable on Sugru I have seen. Thanks for sharing.

    Pay the $2 for a double-sided key at your Home Center. Much cheaper to make a few spares. Safer,too. I imagine that epoxy dust(from the grinding action) would get into the cylinder.I agree that this was a 'secret ad'.

    This is a Sugru ad. Every instructible KoenA1 has done is a quicky Sugru "project".

    This isn't a very good or clever instructable. I would've liked to see the finished product instead of a stock photo. Also, how did you attach the epoxy key to a handle? Does it last for more than a few uses? I imagine the teeth would be worn down by the cylinders, filling the lock with epoxy filings.

    Do you have a photo of the finished key made of epoxy? The one here looks like a stock photo and I'm interested in know how well the copy works compared to the original. My car key cost $135 a piece and it would be nice to have an emergency copy in my wallet.

    This probably wouldn't work for your car keys. Expensive car keys are expenses because of a special transponder microchip in the base of the key, not because of the physical metal key. So while you could make a key that could open the doors and such, that key would be unable to actually turn the car on.

    Some keys are more expensive. While typical house keys (such as C or KW1 types) are cheap, there are some types of keys, such as those for dimple locks, that are much more expensive. Also, some keys have special control measures against copying them: if you took one of those to a locksmith, you would also need to present a legal document authorizing copies before he could legally duplicate the key.

    This is interesting, but to me, one of the most puzzling things is how you get a top on the new key.

    Good idea but not something you want to try with epoxy. Also this can easily be used for criminal activity, ie grab someone's safety deposit key, safe key, etc and make a copy and then when they ain't around the criminal can break into the locked enclosure and steal whatever is there. I'd rather goto a locksmith or key copy place and have my key copied rather and experimenting with epoxy which can easily break off into the lock and then you are going to have an expensive repair bill to get it out.

    use the epoxy copy as the "original" in a key copying machine?

    Whats the point in doing that if you still have the original? Making the epoxy key serves no purpose in my opinion.

    Not a troublemaker, just someone who sees this as if its easy for you to make then its even easier for a criminal to do. This way of making a key costs about $20 roughly whereas taking your key to a locksmith to have a copy made using a real key blank so that you have a spare will only run you about $5.

    This seems an incredibly complicated way to make a non-metal key. When I retired 2 years ago after owning a hardware store for 30 years, I was charging $1.99 (US) to make a simple single cut key, as shown in step 4. This would be a nickle plated brass key and I guaranteed it to work! We cut 16,000 to 18,000 keys a year in our little store and 99 point something-something % of them worked! We could almost always make good working copies from broken keys, too. Why not just have your locally owned hardware guy make your keys?

    I can't figure out why people use the very expensive Sugru for mold-making when there are so many excellent cheaper alternatives.
