Magnetic locks on Vintage Nishijin
There is a master locksmith where I work so I had him look at the lock off one of my Vintage Nishijin in hope to have a key made. He looked at the lock and told me that it was a magnetic lock and you can only get keys made if the lock is licensed to you. The lock works with magnetic places along the key with the north and south poles in a set order so the same poles push the sping loaded magnetic pins back to release the locking mechanism so the key can turn. The number stamped on the lock gives the pin configuration. Unfortunately the pins on my locks fell out before I got the polarity of the pins, but the placement of the pins are in a plastic tapered sleeve along the top of the lock. There are 5 pin locations along the top on the lock for pins but only three are used. You can acess it by unscrewing the 2 screws in the back and you should be able to slide it out. The spring-loaded pin configuration front to back on locks stamped 5 are 1, 2, and 5 and locks stamped 4 are 1, 3, and 5. When I get more info I will post. Until then I am just going to remove the spings and magnetic pins and use a blank key.
