Making Keys for locks
One of my hobbies is picking locks. As part of that hobby, I have attended workshops that have taught me various skills for gutting and repinning locks. One of the workshops was at SteelCon and presented by Mad Bob's Lockpicks. MadBob produce some really nice lock picks, so if you haven't heard of them before, check them out. The picks are so much better than the my crappy GOSO lock picks that I bought form Amazon.
For Steelcon this year, Scott Helme ran a "Stickers for Charity" stall. Madbob dropped off a bag of locks for the stall, and I purchased a couple. The couple in question didn't have any keys. I thought that would be ok, I could just repin them. Then it dawned on me, I would need a key for that. At that point, I had already purchased the locks.

The lock I am going to walk through on how I made a key for is a six pin lock, branded ERA. Since I didn't have any blank keys, I ordered 10 off ebay, and waiting the few days for them to arrive. This is far more than I need for this one lock, so I plan to make a bump key, as well as try to make a key from just imprinting the key.
Tools Required:
- Blank Keys
- Files
- Follower (A tube the same size as the barrel of the lock)
- Shims (or a thin piece of metal which goes between the barrel and the lock)
- Lock Pick (For Single Pin Picking)
- Sand paper
- A vise
In order to make the key, the first thing I needed to do was disassemble the lock. Normally, this is straight forward, as you just insert the key, remove the circlip and pop out the barrel using a follower. So, how do I get the lock out with out the key? I initially tried picking the lock. This was indeed my first reason for actually buying the lock in the first place. After a lot of attempts, I gave up. When I got the lock disassembled, I discovered I had 4 spool pins in it, which had defeated me.
My next thought about disassembling the lock was to pick the lock, but use a shim at the same time. In this case, you only "pick" 1 pin at a time, and push the shim in to hold the pin in place. Once complete, you can either turn the cylinder, or just remove the cylinder with the shim in place, using a follower.
Once I had the lock disassembled, I placed the blank key in to the barrel, to confirm that the blank fitted, and to mark on the key where all the pins are going to sit. I used a cd marker for marking the key. Once done, I put the blank key in to my vise and started to mark the key using a circular file to start each of the cuts. Each one was started with 3 runs of the file over the hole.


Once you have one pin done, repeat for the rest. The entire process took me around 3 hours to cut my key. Once I had completed the key, it is a bit rough and ready.
