Miwa lock

[CycloneJack]

I ran across a book that describes Miwa magnetic locks. The concept behind the security of this lock is the cylinder has magnetized pins, the polarity of which lines up with similarly spaced tiny magnets embedded into the key. The key magnets push the pins "up" out of the plug so the lock can be opened. My question is- Could I take a small metal wire or rod of plastic that is similar in length and width of a miwa key, and attach small magnets that very randomly in their polarity, and "scrub" open a miwa like a normal pin tumbler? I have read elsewhere on this forum that there are certain bypass tools made for these locks, do these work in a similar manner?

Use the wire as a pulsed electro magnet.

The downside to this is that you can permanently mess the lock, and the real key may not work.

Your scrubbing idea sounds kinda neat, but I am not sure how you would go about doing that.

You could, but it would probably be far easier to have just one small magnet of known polarity, then you could decode the lock. The hardest part will probably be finding a way to attach your small small magnet to a piece of wire, at least in a way you are satisfied with. Remember heat is a no go, as you may accidentally reach the curie point of your magnet. Epoxy may work, try it.

On the H2K 2 video, Mike Glasser states that a "magnet on a stick" would work perfectly fine on a Miwa lock.

To be perfectly honest i dont think Mike Glasser would now much about Miwa locks or picking in general judging from his behaviour in that video.

I have a Miwa lock I found on a bike path when I was about 8. I havent been able to open it since then using non destructive methods. If you are willing to possibly destroy the lock, you could make a tesla coil on a stick but theese are VERY dangerous since they deal with high voltage electricity. If the coil is not mounted properly or the coil is not insulated
You could electrocute and possibly kill yourself.

I doubt this scrubbing technique would work but I've seen decoders for Miwa. One of the japanese suppliers sells an electronic decoder but there are also two mechanical decoders available. But these are alphabet soup agencies only, AFAIK.
