Postby skold » 8 Mar 2004 3:03



Ok i have a question about side bars....what the hell are they, i understand that they are on medeco locks and bi locks but i have never understood what they are :?: :!: :?:

ok and another question while i still have the word bi-lock in me head..
i have a padlock a lockwood with a bilock cylinder, it has a round metal disk beside it and i wanted to remove it to have a closer look at the bi locks structure etc. how would i remove it as a locksmith has obviously changed the cylinders at some stage :?:

How to remove the cylinder from the lock. Hopefully there is a screw (hex or phillips) inside where the locking mechanics, when unlocked.

In regards to the sidebar question.

It appears medeco locks the lock needs to be raised to the correct height then the lock is rotated so the hole and the sidebar matches. When all the sidebar notches are set (notches go in the holes on the pins) the sidebar moves towards the pins allowing the lock to rotate. The sidebar I think is what stops the lock (when in the locked position) from rotating.

Bilocks have holes on the side of the pins (and groves to prevent rotation). Basically the sidebar goes into these holes stopping the pins and hopefully they are all stoped correctly so that the sidebars go all the way in allowing the lock to rotate. On bilocks the sidebar is what stops the lock (when locked) from rotating. Bilocks seem to have multiple holes on each pin giving it false sets and the ability to master key.

Like most things I am only guessing with how the sidebar works on these locks and I would appriciate anyone who knows for sure and can set me straight. Also I understand there are a few more locks that have sidebars, how do these ones work? I understand that some wafer locks have sidebars as well. Anyone care to find pictures and explain.
Consider me inactive or lurker.

A sidebar is just another way of restricting the turning motion of a lock. When the pins/wafers in the lock are raised to the right height, there is a groove presented to the sidebar. Putting turning pressure on the sidbar retracts it into the groove formed by the pins, and the lock opens. There are some variations on this theme as well, but thats the basic idea.
