Magnetic Lock

Shaking open

I might buy a padlock from the website above, just to try to shake it to death!

... Alas, there is a far more boring way to defeat this particular lock: use the butt of a screwdriver to tap on the lock while pulling gently on the shackle, if memory serves. It opens almost instantly since the tolerances are more fitting for bumper car races than for NASCAR races.

Thanks for the reminder. You are correct to observe that nobody suggested this technique in this thread.

However, the technique (known as 'rapping') has been several times in the past as a method of using inertia to set the pins to the shear line or otherwise open locks with spring loaded relocking dogs.. I believe it was even suggested on a magnetic lock in a thread about a year ago... (but I am too lazy to search for it).

I am sitting at the shop reading this post waiting for the next old lady who needs a key copied.
Anyway as I sit here gazing at the the security system components that we sell it occured to me that it would be possible to read the polarity of the magnets inside the lock with somthing similar to a magnetic alarm breaker on a door, only a bit smaller. Starting from the back you could read which spots trigger whatever u have rigged up to the breaker and then assemble a key(speaking in terms of miwa) with the proper magnets in place. only problem is that ther breakers are very sensitive so it would have to be extrmly small. but anyway just a thought

TOWCH and I are currently working on a decoder for the Miwa EC. It is a double sided deadbolt that I loaned to TOWCH, but he has both sides.
More info in the advanced forums.

This thread reminds me of those rf locks...you know the ones with the little garage door opener-esque remote. they always looked pretty cheap, and prone to smashing into a million bits to me.

anyone ever see one of these?

What the heck's a magnetic alarm breaker?

What the heck's a magnetic alarm breaker?

I'm thinking it's a magnetic contact switch.

It's those little white blocks you see wired to alarmed windows and doors. Basic ones are just a reed switch and a magnet. More advanced ones measure the magnetic flux, and so trip if you test them with a magnet or compass.

I believe that those magnetic switches only tell that there is a magnet present, but do not tell polarity. Besides, getting those down to a micro size would be hard. Also, how could you not avoid the other magnets?

If you want to beat those locks, you need a small Hall Effect device. Pop it in, and read the magnetic field strength directly for each magnet. Of course, the fancy ones, like a nice magnetic EVVA (?) cutaway I saw, have the magnets mounted on wheels so they spin, rather than raise and lower, as well as a rather neat line of pins of the regular kind, meaning the mag lock part is a nice secondary security device, more like a sidebar!
