Medeco Biaxial Cutaway

Basically the biaxial system offsets the chisel point to the front or rear of the center of the pin. Hence the name of a fore or aft cut. That is the simplest way I can think of to explain how the system works.

DD,

The original medeco rotating pin tumbler was released around 1969 I believe. The biaxial version of the lock was patented in 1985.

What you just described is the rotating pin pricinipal. The biaxial system uses a fore and aft cut system to increase key differs if I am not mistaken. That is what is represented in the pictures. All medeco locks utilize the rotating pin principal, biaxial or not.

I stand corrected. :oops:

Fascinating, there's always something new to learn around here.

Seems you were right Zeke.

You might not see them, but there are false gates on the lock.

Heres my key then, it seems to have a half spaced cut in the middle of the key so does that make mine a biaxial or not?
It also has the nik out at the shoulder which i thought was a common feature of the biaxial key.

Shrub,

It appears to be a standard medeco. I think it is the rotations that are giving the illusions of a biaxial spacing as you have opposing rotations next to each other in spaces 2 and 3 next to a 0 rotation in space 4. I could be wrong though. Easiest way to tell is to look for the biaxial symbol on the face of your lock which appears similar to this o0 .

Nope just got a UL in a circle, guess its not biaxial then.

Time to throw this wannabe piece of crap away then lol

I'll have it!

Just kidding. :wink:

AAAACCCCCCCCKKKKKKK!!!!!!! Dont throw it away!!! They are just as hard to pick as biaxial I think!! Just less key differs.

In simplified terms (I think): the non-biaxial system only allows the pins to rotate to the FRONT (facing the rear of the lock) left, right, or center, whereas the biaxial system allows pins to rotate to the FRONT OR BACK left, right, or center; therefore, the standard system only has 3 possible positions that each pin can rotate to, whereas the biaxial system has 6 possible positions that each pin can rotate to.

Right?

I feel like such a poseur with my non-biaxial lock. :cry:

by **zeke79** » 16 Jun 2006 11:26

No, in a biaxial lock an aft cut an only rotate L C or R in the aft position. It cannot rotatate to the fore poition due to the tab pressed out on the top of the pin. Same goes for a fore cut only it cannot pass into aft positions.

If you don't have a REEEEEAL medeco (biaxial), then you're an emo/skater/poser!!! :lol:

(yes, all three!)

ugh. More confused, thanks zeke.

Hehehehehe, look at it only in terms of increasing key differs devildog. Do you have a biaxial lock you can take apart?
