Ok I have been thinking about making a repinable euro cylinder that doesnâ€™t need disassembling every time I want to add more pins,change the pins or want a new challenge.
At first I was thinking about drilling the caps and tapping them and using grub screws as caps. I got the idea after seeing pictures of a medico biaxial. But then one day I got bored and took my trusty Birmingham screwdriver to a lock to see how it would work without tapping the holes.
-Euro Cylinder Lock
-Thin Piece of Metal (See image in step<>)
-5 Extra driver pins.
First off you will need a standard Euro Cylinder. I used a single sided 5 pin as I had one on my desk when I got bored. I see no Reason why you couldnâ€™t use a double sided lock with as many pins as you like. In fact a lock with more pins is probably a better idea but a 5 pin was the unfortunate lock that was sitting on my desk at the time.
You will need to Disassemble the lock by inserting the key or picking it, removing the C-clips and first turning the plug then pulling it out. A more detailed guide can be found here http://www.lockpicking101.com/viewtopic.php?t=12441
locate the â€œCapsâ€ that hold in the springs and pins at the bottom of the lock.
Now you will need to secure the lock in a vice with the caps facing up, make sure the lock is VERY secure so you donâ€™t hurt yourself.
OK decision time, this step basically renders the lock useless as a functioning lock that could be used in a door. So make sure the lock is not needed. I also pretty much destroyed the screwdriver as well. You will need to use a hammer and the screwdriver to drive the caps through the body of the lock where they will fall in to the space that is usually taken up by the plug. It takes a bit of effort as you are reshaping the caps to fit through the holes.
Ok the hard parts over, now simply reinsert the plug and replace the C-clips.
Now you have reassembled the lock but it contains no pins or springs you are nearly ready to repin it as you wish. But first you need a small piece of metal to stop the springs pushing the pins up. I used a small piece I removed from a Yale lock. Take 3 short pieces of electrical tape about 2â€ or 5cm long and over lap them with the piece of metal in the center.
(I'm sorry I tried and tried but could NOT get a good picture of this but u get the idea)
Now you can repin the lock as you wish from above. Now you will need to add 5 additional driver pins at the opposite end of the springs to the other driver pins to compensate to the lack of caps.
(Note additional pins over the springs to compensate for the missing caps)
And then tape them down making sure the small piece of metal you are using sits over the pins and springs. Then trim the pate to make it look neat and you have a working practice lock you can repin in seconds by simply pealing back the electrical tape and replacing/adding/removing pin sets. You can also add and remove security pins in the same way to make the lock more of a challenge.
