Key Impressioner

thingiverse

I purchased some locks along with a set of keys. Since I have access to rekeying tools, I decided I would rekey them, just in case. However, I have always been curious about making key impressions, but I couldn't find any cheap kits or models online for a mold. This model was made just to have some fun and I used only keys to locks I own, after which the locks were rekeyed. Only make keys to locks you own and don't make a mold of keys to locks that would be bad if they got disabled. The keys made with this process work, but they are considerably weaker than regular keys. As a sort of jack of all trades, I wanted to try doing a key impression to copy a house key. I was able to make it open a door, with some persuasion. It is a double-sided mold but both sides are the same so just make sure you print off 2 copies of the file. The pegs are fairly tight from my printer, they are also fairly weak so I worked them into the hole a little at a time. - I found the coarser layers actually helped it fit a little better. - When making a mold of a key, use plenty of pressure. - After you have made an impression, carve out a small airway to let the air escape.
