Hi Secuer

So, I'm looking at the lock on the door to my new place wondering how the heck it works. The back ground I can give you is this. This is the lock, I'm looking at:

The lock, is a flatish cylinder with a narrow slot in the side of it. The key looks like a dog tag. A flat metal oval with a hole in one end for a ball chain. I think they're meant to have a piece of plastic glued to one side, but most have fallen off. The lock itself doesn't appear to be wired,eletricity wise. They're made by a Korean company which you'll see if you go to the index page of that website.

So how does it work? Magnetic is my guess, but specifics I'm afraid I don't see.

Ye gods, their website must be on dial-up or something.

From the description, I think you have a mechanical card lock. Here is a link to a picture.
If that is the one, then yes it is a magnetic lock.

If you google for inurl:hisecuer.com, the first link is their documentation download page. They have manuals and a code changing instructions on the site, but you'll have to be rreeeeeeeaaaaaaaally patient. I'm downloading one at a massive 1kbps. eek.

I have read that mechanical magnetic locks can be "raked" using random magnetic fields from a coil being fed essentially random signals. Based on the designs I saw in the file and my limited electronics experience, I felt it was much more likely to cause electrocution or a small fire than open the lock.

HTH,

A magnetic lock is essentially a binary system then right? What a I mean is two positions per pin, not five. But I can't see how that helps you unless theres a limited number of pins and you can have a card made for each combination. Still that's a lot of trouble. There must be a simpler bypass then frying the thing with an alternating magnet.

Not all magnetic locks are binary-based. Look up the EVVA MCS.
